Choose MMS (with pictures) as the channel on the Send page and a media field appears under the message. MMS delivers to US and Canada numbers; the sending number must be MMS-capable, which the Twilio page’s channel card confirms for you.
What goes in the media field #
- Up to 10 links, separated by
; - Each must be a public http(s) link that opens the file directly: paste it into a private browser window and the image itself must appear, no login, no viewer page
- JPEG, PNG and GIF are the safe formats; keep files under 5 MB (well under 1 MB delivers fastest)
Google Drive and Dropbox share links open a viewer page, not the file, so carriers reject them. TextBay converts them for you: click Convert Drive or Dropbox share links under the media field, paste the share link, and use the direct link it produces. The file itself must still be shared publicly (“anyone with the link”).
A different picture per person #
Give a contact a detail named media_url (on the Contacts page or in your import file) and that link overrides the campaign’s media for that person: personalized coupons, per-customer QR codes, and so on. People without the detail get the campaign’s media.
Cost and WhatsApp #
Twilio bills MMS at its own per-message rate for the destination, separate from SMS segment pricing; the confirmation dialog shows your live balance before the run. On the WhatsApp channel the same field takes a single attachment link instead of ten: WhatsApp allows one per message.
