Where MMS works
Three things must be true to send a picture.
ConnectSMS checks all three before the message is sent, and tells you which one is missing instead of sending something that can't arrive.
Your business number
An MMS-capable number
The number you send from must support MMS in Twilio, which ConnectSMS reads when numbers are synced. If it doesn't, choose a number that does, or send text only.
Your admin
Attachments turned on
MMS is off until an admin turns on Allow attachments through temporary public links in ConnectSMS Setup, under Policies.
Files and limits
What you can attach, and how much.
Pictures are fully supported. A small set of other file types is allowed at a smaller size, in line with Twilio's guidance for carrier compatibility.
- Up to 10 files and 5 MB in total per message
- JPG, PNG and GIF pictures, within the 5 MB total
- PDF, vCard, TXT, MP3, M4A, MP4, 3GP, WebP and BMP files up to 600 KB each
- The composer shows each file's size and your running total as you attach
| What you attach | Formats | Limit |
|---|---|---|
| Pictures | JPG, PNG, GIF | Fully supported, within the 5 MB total |
| Other files | PDF, vCard, TXT, MP3, M4A, MP4, 3GP, WebP, BMP | Up to 600 KB each |
| Per message | Any mix of the above | Up to 10 files and 5 MB in total |
| Message text | Optional, alongside the files | Up to 1,600 characters |
Temporary public links
How your files reach Twilio, and when the link is gone.
To send a picture or file by MMS, Twilio has to download it from a public link. ConnectSMS keeps that link as narrow and as short-lived as it can.
Turning attachments on asks the admin to confirm, so it's a deliberate decision that matches your policies.
- The link is created when the message is sent, not when it is written
- It points to the exact file version attached to the message; the record and other files aren't shared
- Anyone who has the link can open that one file until the link is deleted
- ConnectSMS deletes it after the hours set in Delete each link after sending (hours): 24 by default, from 1 to 168
- Twilio and the recipient's carrier receive a copy of the file to deliver it

The life of an attachment link
- File attached in Salesforce
- Message sent: link to that file version
- Twilio downloads the file
- Carrier delivers the MMS
- Link deleted after 24 hours
Sending
Attach files wherever your team texts.
On a record page, choose Attach file from the composer's ⋮ menu; in the shared inbox, use the paperclip. Automation can attach files too.
-
Upload or choose a file
Upload a file, or pick one you already have in Salesforce Files. A file uploaded on a record is also saved to that record.
-
Checked as you attach
Each file shows its size, with a running total against the 5 MB limit. The composer lists the allowed file types.
-
Told before you send
If the number can't send MMS, the recipient is outside the US, Canada or Australia, or attachments are off, the composer says so.
-
Checked again at sending
When the message is handed to Twilio, ConnectSMS checks the MMS rules and the sender's access to each file again.
-
From Flow and Apex
The Send Text Message action takes File Version IDs, and
ConnectSMSApitakes the same, with the same limits and admin setting. -
Billed by Twilio
Twilio charges MMS rates to your own Twilio account. ConnectSMS adds no message-plan limits.
Received media
Pictures customers send you open in Salesforce.
When a customer texts a picture or file, it arrives in the same conversation as their message, on the record and in the inbox.
- Pictures (JPEG, PNG, GIF, WebP, HEIC and BMP) open from the conversation with View Picture
- Audio, video and PDF files can't be previewed, but can be downloaded
- Other file types are never opened, to protect you from harmful content
- The dialog shows the file's real type and size before you download anything

Twilio and the carriers decide final delivery
ConnectSMS checks the message, creates the links and hands it to Twilio. From there, Twilio and the recipient's carrier download, deliver and sometimes resize or reject the media under their own rules. The message status shows what they report back, so a picture is only marked Delivered when the carrier confirms it.
Outside the US, Canada and Australia
Send the message as text only: text messages go to any country. ConnectSMS won't send attachments to numbers in other countries, and it tells you why rather than letting the message fail later.
FAQ
MMS from Salesforce: common questions
Can I send MMS from Salesforce?
Yes, once an admin turns on attachments. Pictures and files are sent as MMS to US, Canadian and Australian numbers from MMS-capable business numbers, up to 10 files and 5 MB per message. ConnectSMS shares each file through a temporary link that expires after a set number of hours.
Which countries can receive MMS from ConnectSMS?
Pictures and files can be sent to US, Canadian and Australian numbers, the countries where Twilio documents MMS delivery. Text messages have no country limit, so for a number in another country, remove the attachments and send the message as text.
Which file types can I send by MMS from Salesforce?
JPG, PNG and GIF pictures are fully supported. PDF, vCard, TXT, MP3, M4A, MP4, 3GP, WebP and BMP files can be sent up to 600 KB each. A message can carry up to 10 files and 5 MB in total.
How long do the file links stay available?
ConnectSMS creates a public link to each file when the message is sent and deletes it after the number of hours your admin sets: 24 by default, anywhere from 1 to 168 hours (7 days). Until then, anyone with the link can open that one file. The record and your other files are not shared.
Can customers send pictures to Salesforce?
Yes. A picture a customer sends appears in the conversation with a View Picture link that opens it in Salesforce. Audio, video and PDF files can be downloaded, and other file types aren't opened, to protect you from harmful content.
Is MMS delivery guaranteed?
No. ConnectSMS hands the message to Twilio, and Twilio and the recipient's carrier decide whether and how the pictures and files are delivered. The message status shows what they report, and Twilio charges MMS rates to your Twilio account.
