Why IP reputation matters

IP stands for Internet Protocol — a unique number given to each device to track its online activity. To deliver your campaigns fast, Mailpro sends from hundreds of IP addresses. Every email originates from one of them, and IP reputation is how inbox providers judge whether that address is trustworthy or a source of spam.

This is one of the most important factors to weigh when choosing an email marketing provider: you want one that sends from reputable IPs. If the IP your provider gives you has a bad reputation, chances are all of your emails land in the SPAM folder — no matter how good your content is — and you pass unnoticed by your customers.

With Mailpro you can rest assured. Our team of specialists closely monitors the reputation of our IPs to make sure they aren't blacklisted and that your mail is delivered in a timely manner without falling into Spam. Combined with strict legal terms and conditions and a zero-spam policy, that keeps other customers' sending from ever affecting your own.

Best of all, we manage this for you at no extra cost. When you send from our managed IP pools — a top-quality group of IPs selected for you — you never have to worry about IP reputation, unlike a single dedicated IP where the reputation is entirely your responsibility. Delivering emails is our specialty, and our experts are on hand to guide you every step of the way.

QUESTIONS

Frequently asked questions

What is IP reputation?
IP reputation is the sending history attached to a mail server's IP address. Inbox providers use it to decide whether to trust your email — a poor reputation, or a blacklisted IP, sends your messages straight to Spam.
Do I need a dedicated IP for a good reputation?
No. Mailpro actively manages the reputation of its shared IPs for you, at no extra cost. A dedicated IP is optional and mainly useful for high, consistent sending volumes. Learn more in our deliverability guide.
