To send an email as an SMS with Mailpro, write an email to +[country code][mobile number]@sms.mailpro.com from an address you have authorized in your account. Mailpro's Email-to-SMS gateway converts the email into a properly formatted SMS and delivers it to the recipient's mobile in seconds. That lets your CRM, helpdesk, monitoring system or any tool that can send email but not SMS send text messages too.
How does the Email-to-SMS gateway work?
- You send an email to a special address:
[email protected](the local part is the recipient's mobile in international format). - The gateway authenticates the sending address against your account.
- The email body is converted to an SMS, billed against your SMS credit and delivered.
What format must the email follow?
| Field | Rule |
|---|---|
| Recipient | +<country code><mobile>@sms.mailpro.com — example [email protected] |
| Sender | Must be an authorized sender of your account |
| Subject | Optional. If empty, only the body is used |
| Body | First 160 GSM-7 characters (or 70 Unicode) become the SMS — see country codes |
| HTML | Stripped automatically — only the plain-text part is converted |
Write the mobile number in international format: plus sign, country code, then the number without its leading zero. A French mobile 06 12 34 56 78 becomes +33612345678. No spaces, dashes or parentheses.
Keep the text short and plain. Email signatures, legal footers and quoted replies count as body text too, so turn them off for messages sent to the gateway. A single emoji or special character switches the SMS to Unicode, which lowers the limit to 70 characters; see the SMS character limit for details.
Example
To: [email protected] From: [email protected] Subject: (empty) Body: Server web-01 is down since 14:02. Check the status page.
How do I set it up in my Mailpro dashboard?
Open SMS → Email-to-SMS gateway, add the email addresses (or domains) allowed to trigger SMS, and copy the generated gateway address. Test the gateway by sending an email from one of those addresses to your own mobile number.
The name or number shown as the SMS sender is set in your SMS settings: see how to configure the SMS sender name.
Is this different from carrier email-to-text addresses?
Yes. Some mobile carriers offer their own free addresses (number@carrier-domain) that turn an email into a text, but you must know each recipient's carrier, the domains change, delivery is not guaranteed and there is no report. A business gateway like Mailpro's works with any carrier: you only need the number in international format, and you send from addresses you control.

Common integrations
Almost any system that fires email notifications can be turned into an SMS trigger: Zabbix/Nagios alerts, Jira ticket events, Stripe payment receipts, Calendly appointments, Google Calendar reminders. Most need only a copy/paste of the gateway address into the “notify by email” field.
Why didn't my SMS arrive?
- Sender not authorized: the “From” address must be on your allow list, exactly as written.
- Number format: a missing plus sign, a leading zero kept after the country code or spaces in the address.
- No SMS credit left: each SMS is billed against your balance.
- Text cut off: only the first 160 GSM-7 (or 70 Unicode) characters are sent, so put the key information first.
Pricing
Each delivered SMS uses one credit from your Mailpro SMS balance. There is no extra fee for the gateway itself. See SMS pricing for current per-country rates.
Frequently asked questions
Can I send one email to several mobile numbers?
The local part of the gateway address is a single mobile number, so each address reaches one phone. To text a whole list, use an SMS campaign instead.
Can I use it for marketing messages?
The gateway is designed for alerts and notifications. For promotional SMS, use an SMS campaign and only text people who gave consent; rules differ by country, see SMS laws and restrictions.
Are attachments sent?
No. Only the plain text of the email becomes the SMS; HTML and images are stripped.
