Question : How to Use Mailpro to Send SMS?

Sending SMS through Mailpro takes the same shape as sending email: import a list of phone numbers, draft your message, set the sender, and schedule or send. The difference is in the constraints: 160 characters per segment, country-by-country regulations, and a paid credit per message.

Step-by-step: send your first SMS campaign

1. Top up your account with SMS credits (or activate the SMS option on your subscription).
2. Open SMS in the main menu and create a new campaign.
3. Import your phone list in international format (+country code first, no spaces).
4. Draft the message body. Mailpro shows the segment count and remaining characters as you type.
5. Set the sender name (default mailpro.com, or your validated SenderName).
6. Send a test to your own number to check formatting.
7. Send immediately or schedule the send for later.

SenderName: brand the sender field

By default, recipients see mailpro.com as the sender. The optional SenderName service lets you replace this with your brand name (max 10 alphanumeric characters, no spaces) or a phone number. SenderName must be validated — you send your company registration certificate and an ID copy to [email protected]. Carrier compatibility varies by country: some operators may override your SenderName at delivery, and Mailpro prioritizes delivery over preserving the sender ID.

Personalization, segments, and scheduling

• Personalize messages with merge fields (first name, custom data) for higher engagement
• Use the same segment logic as email to target only the relevant subset of your contacts
• Schedule for the optimal local time per country — or split sends across time zones
• Set up automatic birthday SMS for personalized one-to-ones

Costs and credits

SMS credits are independent from email credits and are non-refundable once paid (except where applicable consumer law requires otherwise). One message segment is 160 characters in GSM-7 or 70 characters in Unicode (emoji, accented letters). Long messages auto-split into multiple segments and consume a credit per segment.

Legal compliance

Before sending, confirm you have explicit prior consent from each recipient. Read SMS laws and restrictions for the country-by-country rules — opt-out keyword (STOP), sender identification, and quiet hours apply almost everywhere.
