10 Factors to Verify Before Choosing a SMTP Server

10 Factors to Verify Before Choosing a SMTP Server

Emailing continues to be a fundamental piece in the marketing strategy of any business or company, not only to promote brands, but also to send customers transactional messages with content such as purchase receipts, invoices, account statements and everything related to transactional processes.

When you have a growing business and need to deliver a bulk of interactive emails to your users, you will often run into limitations when trying to send them with commercial email providers. Ultimately, these providers will prevent your messages from reaching their destination. In this case, a SMTP Relay server provider can help you deliver large volumes of emails without them being labeled as Spam and will put an end to your emails not reaching their destination.

The big difference between a “normal” SMTP Server (such as those used by Gmail, Outlook or Yahoo) and an SMTP Relay server, is its ability to guarantee the unlimited sending of your emails quickly, and directly from the application without having to worry about blockages or limitations.

There are some details that you should take into consideration before choosing the ideal SMTP Server for your business. At Mailpro, we have selected the most important points that you should consider before choosing an SMTP server.

Factors to consider to select a SMTP Relay Server

When it comes to features shared between SMTP servers, you will find that some are very similar. In this list however, you will find the 10 most important features that will indicate if you are choosing the right SMTP server for your business.

Scalability: The scalability of a server is essential for a growing business, it is important that it can be adjusted to the needs of your company as the number of customers or users increases. Whether you are sending emails to a small group of contacts or sending transactional emails to a large volume of clients, the SMTP server must be suitable to grow alongside the volume of your company.

Message Metrics: Having the statistical data of all your deliveries through an SMTP server gives you complete certainty that your messages have reached their recipient. In Mailpro we make sure that the statistics for SMTP server show you the number of messages delivered, opening percentages, click percentages and you can also verify the bounce rate of your messages delivered.

Access to SMTP server statistics is a solution that is not present in all providers, so you should verify very well before choosing the one indicated. Using a solution that does not give you SMTP sending statistics, you would have no way of measuring and analyzing whether your messages are really engaging your customers, which could be harmful to your brand, as you would be making an investment without testing its capacity for success. 

Complete data security: The security of your servers and the data you receive in is one of the most important aspects. Data is one the most valuable assets that your company can count on, so it must be fully protected from the abuse of Spammers and unauthorized people.

Mailpro offers you a robust server infrastructure hosted in Switzerland, where all stored data is protected by federal laws and nobody can request your data, whether physical or digital. What differs from countries such as the United States, where data protection laws allow any government entity or agency responsible for complying with the law, to request your data and gives them access to all your data, if necessary, before any investigation.

IPs Reputation Management: Additional value comes from having a team of deliverable experts in charge of ensuring that the reputations of all the IP’s used to make their deliveries are of quality and thus ensure that no blacklisted IP’s slip through the cracks and lead your messages straight to spam folders.

Simple Integration: An SMTP Relay server simplifies the process by supporting all the main email clients, software or applications and making it easier to configure and connect to them. A few simple steps in which you can integrate user and password authentication, are enough for you to send all the messages you need.

Support when you need it: Having a support team you can depend on is a benefit that cannot be ignored, as having a team that is always present to help you with all your doubts about installation, routing processes, etc. is a factor that should be decisive when hiring the services of an SMTP Server. In Mailpro, you can find a multilingual support team that is willing to answer all your questions and assist you with technical details.

Authentication and protection: Exclusive security passwords for the installation of your server in each software or application you use. SMTP authentication is configured to increase security levels and prevent your account from being used without authorization to send SPAM emails. The SMTP Mailpro server gives you the ability to generate a new password when making a new system integration.

High deliverability: A robust server infrastructure and proven delivery rate will allow you to be sure that all your transactional and commercial messages reach each recipient. SMTP Mailpro servers are fully suited to support large sending volumes, and you can also enjoy a high delivery capacity when installing SPF or DKIM.

Return management: In case any of the emails failing to reach their destination, the system must include a message explaining why the delivery of the email has failed and allow you to make the necessary changes.

ISP Compatibility: The SMTP server you select must give you access to any Email Service Provider from where you are, thus giving you the freedom to access the service without restrictions.

What is the Best Port Number for SMTP?

What is the Best Port Number for SMTP?

When configuring the SMTP Relay server to your email or application, it is common for doubts to arise about which email ports to use. So, what kind of ports should you use? Which are safe and secure? In this article we will briefly summarize which ports you can use to send emails through the SMTP Mailpro servers.

The Simple Email Transfer Protocol (SMTP) is the basic standard used by email servers and some applications or services that support SMTP relay. With regards to "storing and forwarding", the SMTP Protocol is responsible for the transfer of emails by working directly with an email transfer agent to send the communication from the computer to the recipient's inbox.

The connection ports are the communication points through which the transfer of all data and communications takes place, each of these has a particular purpose as well as being associated with a specific protocol. An SMTP port is the specific part of the internet address that is used to transfer emails.

The common standard SMTP ports are 25, 465, 587 or 2525. Mailpro offers you the standard SMTP ports 25 and 587 to perform the mail transfer.

 SMTP server providers such as Mailpro have been concerned with investing in the creation of infrastructures for the relay of emails to large volumes and strictly monitoring the security of the relay process in order not to allow junk traffic that affects the SMTP exchange process.

Ports 25 or 587, which of the two to use?

Port 25, the original standard

Many of the emails sent are routed through port 25, which becomes the communication channel between the email client and the email server. The IANA (Internet Assigned Numbers Authority) recognizes port 25 as the default standard port for mail transfer between servers through a point-to-point connection. Its connection to the SMTP server is produced by text commands sent from the SMTP server. This is the default port, but, when used extensively, it is also more susceptible to large amounts of spam and unwanted traffic.

Port 25 is still used primarily for SMTP relay, but more and more Internet providers (ISPs) are restricting the use of port 25 due to its widespread use for spam. Many ISPs and service providers restrict connections to port 25 to reduce the number of spam emails.

Port 587, safe harbor

Port 587 is another port for SMTP sending compatible with most servers and recognized for the safe sending of your emails through the SMTP port. It is recommended that when configuring your SMTP connection, to use this port as default to send your emails securely and thus ensure that all messages reach their destination.

With Mailpro, you can work from ports 25 and 587, which are the standard ports and subsequently, you will not having to perform an encryption and decryption task, making everything much easier. Through the authentication of the SMTP Mailpro Server, you ensure the unique access to your SMTP Server Mailpro, once you have done the configuration of our SMTP server you will not have to perform a reconfiguration on each connection.

What is the Pre Header and Why is it the Ideal Complement in your Campaigns?

What is the Pre Header and Why is it the Ideal Complement in your Campaigns?

The Email PreHeader can be defined as the text summary that lies next to the subject line when you view the mail from the inbox. It is that line that gives an idea of ​​what the message contains, this line of text that for many may go unnoticed but makes a big difference when convincing the reader to open the message or not.

For some, Preheader text will have been completely unbeknownst until now but email clients actually extract this information directly from the email content, specifically from the first lines of content they can find.

Sure you will ask... but if it is generated automatically why you should pay so much attention to it? A big reason is that this text is one of the first three elements that are displayed in the inbox next to the subject line and the recipient or potential subscriber will see this before making the important decision to open the message or not.

The importance of a good PreHeader

When used consciously, the PreHeader text has the power to be that ideal complement to the subject line that will make all the difference and help you increase the opening rates of your emails. A well-written Pre-header will show an accurate and attractive summary of the message that will be displayed to your readers.

Some of the usual errors that may appear in the Pre-Header are shown automatically and it will show messages such as: "If this message is not displayed correctly, click here". It wouldn’t look so good for the reader to see this text accompanying your well thought out subject line.

The self-generated Pre-Header text may seem sufficient, but you’d be missing the opportunity to generate curiosity and capture your reader’s attention.

How can you control the text that appears in the Pre-Header?

To avoid seeing unattractive text and maintain the relationship between Issuer-Subject-PreHeader between texts, you can take some of these solutions into account.

Hide the PreHeader text: Lead readers directly to the design of your newsletter by adding a hidden div style code in the HTML code of your newsletter’s design which will allow you to insert a hidden text that will be displayed by email clients. The drawback is that these email clients modify the rules frequently, which forces you to adapt the code so that it works for everyone.

An example of the code to solve it manually would be:

<div style = ”display: none! important; mso-hide: all; ”> Pre-Header Text </div>


Use a Professional Email software: When you use a professional email tool like Mailpro you will simply need to insert the text you want to show as Pre-Header from the advanced options that our platform offers you to design messages.

Using the Message Builder, simply go to the advanced options, in the “Pre-Header” line, and add the text you want to display.

If you have designed your Newsletter in HTML code, when importing it to Mailpro you can go directly to advanced options in the WYSIWYG editor and insert the text, so you will save time and you can be sure that the Pre-Header will be viewed correctly.

This is where you should take the opportunity to place that message that complements your powerful subject line and serves as a hook for capturing the attention of your subscriber. If you create your message from Mailpro, it will only take you a few minutes to place the appropriate message in these boxes. It’s simple.

Keep in mind that the most important information should be present in the first characters that you include in the content of your message. To get the best results and get the most out of using Pre-Header text in your email marketing campaigns, keep the following tips in mind:

  • Include a call to action that helps you increase the opening percentages of your campaigns. Think of including a line like “Discounts for End of Season” in the Pre-Header.
  • Provide relevant information that complements the subject line. This text will help to reaffirm or expand the message of the email title so that it is consistent with the subject line. This space allows you to expand what you consider important to show the reader.
  • Must be attractive. Create expectations and contain few but concise words. Complement it with resources of exclusivity and customization to make it even more attractive. Always keep in mind that personalization in the email helps increase opening rates. Adapt the message as much as possible to make it a direct conversation with the client from the very first look at the inbox.
  • Be creative and fun. Use the PreHeader text to give you freedom for ideas and creativity. Write something different to help capture the reader's attention, a bit of sparkle and humor always comes in handy. Without forgetting that everything depends on the content of the message, never lose the relationship with the content. You don't want to confuse the reader and have it send you directly to the SPAM folder.
  • Do not repeat the subject line. Take advantage of the space and additional characters to gather the reader's attention.
  • Think mobile. The pre-headers may not be quiet as valuable when you open emails from a computer but on mobile devices they can be as important as the subject line.


Using all possible resources to make your message stand out from the amount of emails received daily is one of the challenges of email marketing. In your next campaign, do not forget to create a suitable text for your Pre-Header. Including the correct message as a complement to an attractive subject line will capture the attention of your readers and will be a reason that leads them to open the message.

In order to achieve all the objectives you propose in your email campaign, it is important that you use a professional email marketing platform such as Mailpro, the platform that integrates everything you need to manage the design, delivery and statistical analysis of your email marketing campaigns.

SMTP Relay vs Email API, Advantages and Disadvantages of Each

With Mailpro you can integrate your application, ecommerce or website through SMTP or API.  Which one you decide to use depends on your needs, which is more convenient for you, and on the amount of money you would like to invest in coding. We will try to guide you through the advantages and disadvantages of each in this article.

SMTP stands for Simple Mail Transfer Protocol and is a set of rules used to send emails. With Mailpro's SMTP Relay Server, first, your will connect your software to our SMTP Server and we will then send your emails from our own infrastructure (with its outstanding IP reputation), a Tracking system if required, and much more.

Basically the SMTP will allow you to create and send emails from your application and send them to the server, while an API gives access to the applications through code.

First, let’s begin with the advantages of SMTP

Some of the advantages of SMTP compared to API are:

  1. No Coding required: It is extremely easy to start using Mailpro for your transactional emails. All you have to do is exchange credentials and you are set to go.  Unlike with API, where Coding is required.
  2. Connect to all Systems: all you have to do is use your credentials and it will work.
  3. In case of failure, the message will include an explanation about why the email failed to be delivered.

Disadvantages of SMTP

  • Usually requires more back and forth conversation between servers in order to deliver your message, which can delay sending and also increase the chances of the message not being delivered.
  • Some firewalls can block ports commonly used with SMTP.

Advantages of the Email API

API, on the other hand, stands for Application Programing Interface, and is a way in which applications, and softwares communicate or share information between each other.

  1. API’s in general have a way quicker delivery speed as there is less back and forth required between servers.
  2. Less Chances for the Potential Failure of your message.
  3. Extra level of security with API Key, that only your website, application or platform can access.
  4. API’s are accepted by most firewalls when using HTTP.

Email API disadvantages

  1. You need programming knowledge to configure and execute the shipments.
  2. API requires constant modifications and updates stay up to date.

The SMTP Relay Service can be used to connect applications, such as Outlook or your current CRM Software, while APIs are usually used by people developing their own application.

Which is better SMTP or API?

This question varies according to the needs of your brand and your technological experience. If you consider yourself as having enough knowledge in programming, the use of API will be the most attractive option, since it offers you the possibility to customize and modify the configuration so that it fits your needs.

If you are looking to integrate the sending of emails to your platforms without the need to apply any code, SMTP is your solution. In addition to the simplicity of its execution, the Mailpro SMTP Relay service gives you access to the metrics of every messages delivered.

The objective of both functions is the same; linking your applications to send your transactional messages. SMTP is a universally used standard mail protocol that can be connected to applications such as CRM. The API is used mainly by developers who create their own applications.

You’re using either SMTP or API depends completely on your needs, and also on the capacity of your application, website or e-commerce.

As you can see, there are two advantages and disadvantages between both functionalities; the SMTP protocol allows you to integrate in a simple way by following a few steps, but if you are looking to safely process highly confidential information through email, the key provided by the API may be your solution.

Reasons Why you Should Avoid using "No-Reply" Email Addresses

Reasons why you should avoid using Noreply Email Addresses

A common practice for companies when deciding to create their email marketing campaigns is to use email addresses that do not support a return response, that is, No-Reply Email addresses. These are accounts created for the sole purpose of sending emails, a means of unidirectional communication, that as indicated by the username, does not support users sending emails back.

Email marketing is a tool that seeks to generate communication, build loyalty and effectively maintain close contact with those interested in your brand or services. Having a No-Reply Email address would be completely preventing communication between your brand and the customer.

A No Reply address is an unsupervised email address that prevents customers from making inquiries. For some, the main reason why a no-reply address is usually used, is the lack of resources to respond to customer inquiries via email. It is common for companies that send information such as invoices, purchase receipts, and account statements to use these types of addresses to discourage users from answering emails that only contain this general information.

When creating a strategy for sending emails, it is important that you consider the possibility of offering your subscribers the opportunity to respond to the email you have sent.  Maintaining a channel where communication between the brand and the client can occur in a bidirectional manner, will help users keep in touch with your brand and show that your brand cares about  being close to its users.

Why you should not use a “No-Reply” address

Using an address that does not support answers, is telling the recipient of your emails that you are not interested in their opinion.

In addition to damaging the relationship with your subscribers, the No-Reply would affect the engagement of your brand, as it is a factor that would reduce communication.  The user who seeks to request extra information would not be able to find who to send their query to.

These details would affect your deliverability, because the ISP and anti-spam filters can be configured in such a way that when receiving emails from a non-reply sender, they are automatically sent to spam emails.

Personalizing your brand and creating a proximity with your subscribers are currently some of the most important things to keep in mind when establishing your marketing strategies. If you were one of your subscribers, would you trust a no-reply email address? Most likely, the first thing that would come to your mind is that it is an inaccessible company with little interest in its customers.

Create a two-way conversation with your client

If your messages are commercially oriented, such as promotions, discount announcements or an informative newsletter with information about your product, it is important to give the user a space to answer their questions. Rather than being simply informative, these types of messages should help your brand generate interaction and build a closer relationship with the user. Try making the response address to which the client is directed as descriptive, personal, and friendly as possible, revealing a desire for your brand to  grow closer to its users. Keep in mind addresses such as hello@mydomain.com, peter@mycompany.com or you could even modify the reply address based on your campaign objective, example: conference@mycompany.com

Using personalized addresses shows the user that there is a human and not a machine behind your emails. Maintaining a personalized sending address will avoid giving your customers that image of a cold and distant company. Most importantly make sure to use an email address with a Real username and which is under your own domain (.com, .fr, .es)  as this would be more likely to pass spam filters.

In our article “How to avoid the  Anti-Spam folder and deliver your emails better” you can find information that will help you avoid falling into the Spam folder.

An email address that you can respond to is essential in any email marketing strategy, whether you send commercial or transactional emails. If for any reason you decide to use a no-reply address to send your messages, consider providing an additional address so that whoever receives your email can make inquiries.

If the business model is of the B2B (Business to Business) type, usually a response address is used from some sales staff that can quickly and directly respond to the customer. If you use the B2C (Business to Consumer) model, you could maintain a general response address that is constantly reviewed by yourself or some trained team personnel to respond to customer inquiries.

What is SMTP Relay and How it will help your Business

What is an SMTP server-Mailpro SMTP Server

If you use transactional emails in your business every day, you may have heard the term SMTP. 

The SMTP protocol is very important because it makes a big difference in the emails you send to your customers and in your delivery capacity. It may sound super technical, but we'll give you all the details so you can understand how it works and why it can impact your email marketing campaigns.

What is SMTP?

SMTP stands for "Simple Mail Transfer Protocol." This is a communication protocol used between email servers to send and receive emails.

SMTP is responsible for processing and forwarding emails from a sender to a recipient. That is, it acts as an intermediary between both. For personal use and traditional mailings, free email applications such as Gmail, Yahoo, Outlook, can offer basic functionalities to achieve simple tasks. But, if you manage an ecommerce and need to perform professional actions, you can use the services of an SMTP server to directly connect your systems and send transactional emails without the need to make complex integrations.

It is currently the most used sending protocol and used exclusively for the delivery of large volumes of messages.

How do I send with an SMTP Server?

The process of transferring emails using the SMTP protocol and SMTP servers is known as SMTP Relay. This means that if your company needs to send large volumes of messages, you can use the services of a third party (SMTP Relay) to manage the sending of these emails without the need to use your own Email Servers.

Imagine that you run a small company with few employees and a minimum client volume and that all communications are done through email. In the case of a need to send a reduced number of personal emails, you can manage communication through a common email provider. But, the moment your company starts to grow and the volume of emails and customers increases, the majority of classic email providers (Gmail, Outlook, and Yahoo) limit the amount of emails that can be sent daily and it becomes evident that they are not adapted for sending mass emails.

Then it is necessary that the transactional messages you send, such as purchase confirmations, order vouchers, invoices, etc. are made from a trusted SMTP server that can respond to the demands of your business.

To send an SMTP email, you just need to create the messages in your email client (Outlook, Gmail, Yahoo, etc.) CRM or web application, authenticate your connection to the Mailpro SMTP server with the user and password generated by the platform and send it. If you have placed the data correctly, this email will be sent to the Email Server SMTP Mailpro  and delivered to the recipient's server.

Once you have configured your access to the SMTP server of Mailpro, you can send all the necessary emails without leaving your traditional email software or the external service you use.

What is a SMTP Relay server?

An SMTP server is a server on which  SMTP Relay services are performed. It receives the emails sent by a sender and in the majority of cases, transfers them to another server before reaching its recipient. Compare it with the work of a physical post office, where they receive correspondence from the sender and are responsible for delivering it to the post office of the recipient's city where it will be distributed.

The SMTP servers used by Gmail, Yahoo or Outlook are shared among users, so if you want to send massive messages, this can be a big problem, as you could be using an IP address that is also shared by a Spammer which would immediately ruin the sending you try do.

For this reason,  a good option is to use the services of professional email providers such as Mailpro, who specialize in handling large volumes of emails and that have their own servers and constant monitoring of the IP reputations.

The sender creates the email from his personal account and the server of his email client (Example, Gmail, Yahoo) sends it to the SMTP server, where it is managed and sent to its recipients.
