The US telephone carriers use different networks for delivering SMS messages (text messages) and MMS messages (multimedia messages with photos or GIFs). While we have never seen the carriers have a major problem delivering SMS messages, on at least one occasion we have witnessed multiple carriers are having issues delivering MMS messages (via degraded quality or large amounts of duplicate MMS messages to end users).
Here is the red banner at the top of the app that you will see when our system has detected that the carriers are having problems delivering MMS:
And here is the orange banner at the top of the app that you will see when we have recently seen carrier MMS problems and suspect that it may occur again in the near future:
There are two important things to remember when the carriers are having problems delivering MMS messages:
- SMS message delivery is unaffected
- SMS messages typically perform just as well as MMS messages for a lower cost
As soon as our system recognizes that the carriers are having problems delivering MMS messages, it stops allowing MMS messages to be sent. When this happens, the following things happen in Postscript:
- You are prevented from sending or scheduling new MMS campaigns (please use SMS campaigns instead)
- Keyword replies and replies to responses that are MMS messages are automatically converted to SMS messages, meaning that the media and any emojis are removed from the message. You will be charged the normal amount of credits for the SMS message, but we will not charge you more than 3 credits per message. This is to ensure that your message cost is always less than or equal to the MMS message equivalent.
- By default, automations and scheduled campaigns that are MMS messages will also be converted to SMS messages (per the explanation above). However, you have the choice to set your account to pause all MMS automations and scheduled campaigns instead of converting to SMS (see explanation below).
You have the ability in your Account settings to choose whether you would like to pause scheduled campaigns with MMS messages instead of sending them as SMS messages. We HIGHLY recommend that you DO NOT select this option if you use time-sensitive campaigns, as SMS messages perform just as well as MMS messages in most cases.
Here is where you can change this setting in the Account view:
