The Messaging tab defines how your Organization sends email and SMS communications in Activity Messenger. These settings control default send methods, reply handling, SMS behavior, and internal notifications when clients respond.
Open Messaging Defaults
From the top navigation bar:
1. Click the cogwheel beside your Organization name.
2. Select Modify Organization Settings.
3. Open the Messaging tab.
Access may depend on your user permissions.

Messaging settings apply globally and serve as the default behavior for all communications sent from the platform, including messages triggered by forms, invoices, automations, and manual sends. Most options can be overridden at the time a message is sent.
Proper configuration of the Messaging tab ensures clear replies, compliant messaging, and efficient internal follow-up across all communication channels.

1. Default Message Settings
Default type of message
Select the default channel used when sending messages.
Available options:
- SMS (text message)
- Both email and SMS
This setting determines the preselected channel when creating new messages or automations.
You can still override the channel at send time.
⚠️ Important — SMS Usage Recommendation
By default, we strongly recommend using Email only as your default message type.
SMS messages are billed per message and can become very costly if used unintentionally for large-scale communications—such as marketing campaigns or bulk announcements.
Best practice:
-
Use Email as the default channel
-
Enable SMS selectively for time-sensitive, high-value messages (reminders, last-minute updates, or critical notifications)
-
Always double-check the message channel before sending large distributions
This approach helps control costs while ensuring SMS is reserved for communications where it provides the most value.
Default type of communication
The default communication type controls whether new messages are categorized as Marketing or Non-marketing.
Understanding communication types
Activity Messenger classifies messages into two categories:
- Marketing
- Example: Marketing – Program information
- Non-marketing
- Examples: Reminders, cancellations, waivers
This distinction is critical for compliance. For example, contacts who have unsubscribed from marketing messages can still receive non-marketing communications such as class reminders or cancellations.
Communication types are used for:
- Compliance with messaging regulations
- Managing unsubscribe behavior
- Reporting and audit purposes
⚠️ Important
Always verify the communication type before sending to ensure regulatory compliance.
2. Reply Handling
Reply-to email
The default email address that receives replies when a client responds to an email.
- By default, this will be the email address configured in your Organization's Information tab
- Used unless overridden at send time
- Should point to a monitored inbox to ensure timely follow-up
Reply-to mobile (optional)
An optional phone number used for SMS replies.
- Incoming SMS replies can be forwarded to this number
- Commonly used when replies should reach a shared or monitored mobile device
3. SMS Configuration
SMS reply preference
Defines what happens when a client replies to an SMS message. This setting applies Organization-wide.
Available options:
-
Forward the message to the Organization’s “reply-to mobile” phone
SMS replies are forwarded to the number defined in Reply-to mobile. -
Forward the message to the sender’s mobile phone
Replies are forwarded to the mobile number of the staff member who sent the message. -
Respond with an auto-reply message
Activity Messenger sends the predefined SMS auto-reply and does not forward the reply. -
Do nothing
No action is taken when a client replies.
SMS auto-reply message
A short automatic response sent to clients when they reply by SMS.
- Maximum length: 135 characters
- Used to acknowledge receipt of a message
Example:
“Thanks for your message, we will be right with you.”
Note
To activate this message, select Respond with an auto-reply message in SMS reply preference.
SMS cost control

When enabled:
