One-Way vs Two-Way Messaging

EnrolNow supports either one way or two way SMS.

One-Way SMS: sends messages to your contacts without capturing or actioning replies. This works with both sender ID types.
Two-Way SMS captures replies back into the system so your team can see and respond to them. This requires a numeric sender ID — it cannot be enabled on alphanumeric sender IDs.

Which option is available as well as the end customer experience will depend on your Sender ID type — the name or number that appears as the sender on your recipients' phones.

Sender ID Types

Sender ID Type	1-way SMS (no replies)	2-way SMS (replies)
Alphanumeric (e.g. "SunshineELC")	✅ Supported (replies technically impossible) Displays your organisation's name. No real phone number is attached and therefore responses will not be possible.	❌ Not supported There is no destination for a reply to route to. This is an SMS infrastructure limitation, not something that can be changed with a tech fix.
Numeric (virtual or dedicated mobile number eg. "0400 000 000")	✅ Supported (replies possible but not surfaced) EnrolNow platform allows for settings to be locked to 1-way SMS Recommendation that NO REPLY be included at the end of messages for clarity to recipients Replies may still arrive at the platform but will not be surfaced to your team unless two-way is enabled (this is an SMS infrastructure limitation	✅ Supported EnrolNow platform allows for settings to be permit to 2-way SMS Replies will be captured in the SMS Histories module and recorded against child records. Workflows can be configured to bring replies to the attention of team members
