Yes, however MMS is only available through Twilio and only on US and Canada phone numbers. See here for more info: Twilio MMS
Please be aware as well that the mobile carriers are much more restrictive in letting someone send many MMS messages from 1 long code number in rapid succession since there is much more bandwidth to factor in when sending actual images versus just sending regular text. It is much more imperative to assign multiple numbers to a user account and then rotate through those numbers when sending bulk MMS. It’s best to distribute the load of your MMS traffic, so that MMS messages are sent from as many different outgoing phone numbers as possible.
In many cases, clients will use the platform to send new subscribers a MMS auto-reply after they join the list by texting in a keyword, and then send these subscribers regular SMS messages going forward. For example, we have realtors using MMS, but they are using the MMS feature when people text in a keyword to find out more about a property and the MMS images are returned in the auto-reply. They then use normal SMS when notifying their list about updates to the properties, etc…
Due to the nature of long codes and MMS, it’s best to use MMS only in the auto-reply when user’s text in a keyword or in the scheduled autoresponders or birthday wishes. Sending bulk MMS using long codes is restrictive.
