One Time messaging campaigns in the SMS channel

SMS One-time campaigns allow you to send bulk messages to a specific audience in a single delivery. They are ideal for one-off communications such as promotions, announcements, reminders, or urgent notifications.

✅ Before setting up your first One Time campaign, make sure you:
  1. Have the SMS channel active in Engage, requested through a service request in the Support Center.
  2. Have message templates previously created for this channel.
✅ Once these requirements are met, the process consists of three main actions:
  1. Create the campaign.
  2. Upload the audience.
  3. Send the campaign.
▶ Enable the inbound messages feature:

You can activate the "Enable inbound messages" option for cases where you need users to reply, such as appointment confirmations or payment reminders.

To use this feature, you must have a service that receives and processes user responses. You can use our Studio platform or your own service.

⚠ Important note: In the LATAM region, the availability of operators and countries that allow interaction (meaning users can reply to SMS) is limited. To confirm if it is enabled in your country, check with your CSM or contact our Support team through the Support Center.

If you decide to use this feature, the steps are:
  1. Set up your service (you will need one for each campaign created), ensuring it can handle all expected user responses.
  2. Create the campaign:
    a. Activate the "Enable inbound messages" option.
    b. Insert your endpoint.
    c. Select the preferred authentication method and enter the required credentials/data.
  3. Upload the audience.
  4. Start the campaign.
