I am helping a client design and implement MobileConnect - and have come across some functionality issues and questions. Can someone with MobileConnect expertise help with addressing all or some of these items?

  • Client would like to be able to monitor ‘crisis messages’ from contacts – so either be able to monitor specific inbound texts, or extract these contacts and communicate with them somehow. I know there is no 2-way messaging feature on MobileConnect, but are there other ways around this? Some way to monitor and extract by specific Keywords maybe? Client has Service Cloud so would like to route these messages over. I found these 2 potential solutions, looking for the most effective/simple solution though:

Capture long customer reply to SMS sent with Mobile Connect


  • If 2 people (2 subscriber keys) share the same mobile number and we are able to link them to our SFMC data model, then we use personalization in a SMS (e.g. referencing a ‘FirstName’ field in a linked DE), how will the personalization render? Which contact would win?
  • Do we need the compliant message in every SMS (e.g. ‘4 msgs/mo. Reply STOP to quit, HELP for info. Msg & data rates may apply.’)?
  • The compliant # of messages per month (e.g. 6msgs/mo) – does this include response or Next messages?
  • Is it possible to set multiple blackout periods?
  • Will sends slow down with large volumes? And around how long would it be, would throttling be required? (Client estimating sends may average between 100,000 to over a million contacts at once)
  • Overall – client would like to understand capabilities, use cases, and limitations with keywords, so any other resources or documentation you have outside the Help documentation would be great to provide as well

Thank you very much!

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.


1) There are actually several 2-way messaging options available in MobileConnect. Check the availability of the SMS templates on that Account.

2) MobileConnect allows only one Contact to have one specific number as the Priority1 number. Meaning if this number also exists on some other Contact as Priority2 number, it is still/always sent to the Contact that has it as Priority1 and any personalization is also taken from that Contact attributes.

3) You do need to be compliant in all messages that are Marketing related, but Transactional messages can be treated in similar fashion as Transactional Emails. Though it really comes down to the specific country it is sent to.

4) Unclear what do you mean by compliant number of messages..

5) No, in MobileConnect you can have only one blackout window setting per BU.

6) Long Codes send 1 message per 1 second, Short Codes send 100 messages per 1 second. You do the math.
