Send and Receive Text Messages via Email (SMS/MMS)

SIPSTACK supports SMS/MMS text messaging through your email client. When enabled on your account, incoming text messages are delivered to your email inbox, and you can reply directly from email to respond.

Note

SMS-to-email must be enabled on your phone number by your administrator or SIPSTACK Support before you can use this feature.

Receiving Text Messages by Email

Once your phone number is enabled for SMS-to-email, incoming text messages are automatically delivered to the email address linked to your voicemail and direct phone number (DID). No additional setup is required.

• Reply to the email to send a text message back to the sender.
• Group messages may arrive with multiple phone numbers in the subject line. You can reply to all (up to 10 recipients) or reply to a single number.

Sending a Text Message by Email

To send a new SMS or MMS from your email client:

1. Open your email application and compose a new message.

2. In the To: field, enter:

   msg+<your-phone-number>@<system-domain>.sipstack.net

   Replace <your-phone-number> with your SIPSTACK number including country code (e.g., 18005554444), and <system-domain> with the domain provided by SIPSTACK Support.

3. In the Subject: field, enter the destination phone number including country code (e.g., 14165554444).

4. Write your message in the email body.

5. Send the email.

Caution

Remove any email signatures containing images before sending. Images in your email body or signature are treated as MMS attachments and will be included in the text message sent to the recipient.

Setting Up Permissions

To activate SMS-to-email, you need:

• A valid email address linked to your voicemail
• An assigned direct phone number (DID) with SMS capability

If you send a test message to your number and receive no email (check your junk folder too), contact SIPSTACK Support or your PBX administrator to enable the feature.

SMS Methods Available

SIPSTACK supports multiple methods for sending and receiving SMS/MMS:

Method	Description
Email	Reply-based SMS via your email client
Switchboard	Web-based messaging within the SIPSTACK portal

Note

Only one SMS method can be active per extension at a time. Email is the default when SMS-to-email is enabled. To switch methods, contact SIPSTACK Support.
