Setting Up the Twilio Plugin to Send SMS

Support Team
  • Updated
Webmecanik Automation allows you to send SMS messages during your campaigns through the Twilio router. 💬
You must have an active Twilio account to send SMS messages. Start by creating a Twilio account by clicking here.
 

Step 1: Account Authentication

Log in to your Webmecanik Automation account, then navigate to the Plugins section by clicking the gear icon in the top right corner. Click on the Twilio plugin.
Under the Enabled/Authenticated tab, paste the Account SID and Auth Token retrieved from your Twilio console at: https://www.twilio.com/console.
 

Step 2: Messaging Service Configuration

Go back to your Twilio dashboard to retrieve your messaging information:
  • Navigate to your Messaging Services section.
  • Copy the Messaging Service SID.
  • Back in Webmecanik Automation, paste this SID into the Features tab.

💡 Sender Name Character Limit (Sender ID)

If you decide to configure a custom Sender Name (Alphanumeric Sender ID) in Twilio so contacts see your brand name instead of a phone number, keep in mind that the strict limit is 11 characters.
To be accepted by Twilio:
  • The name must contain at least one letter (it cannot be numbers only).
  • Allowed characters include letters (a-z, A-Z), digits (0-9), and spaces.
    To learn more or verify which countries support sender name display, please refer to the official Twilio documentation on Alphanumeric Sender ID.

Step 3: Publishing and Additional Settings

  • Set the Published toggle to Yes.
  • Click Save & Close. ✅
In the "Features" tab, you can also set maximum sending frequency rules (e.g., limiting the number of messages per day) and/or disable URL tracking.
⚠️ Important: To send SMS messages, your contacts' phone numbers must include their country's international prefix (e.g., +1 for US/Canada or +33 for France).

 

Setting Up SMS Opt-Outs

We strongly recommend implementing an opt-out method for marketing SMS messages, such as allowing contacts to send a STOP keyword to 36086. 🛑
However, the SMS industry cannot guarantee 100% processing of opt-outs. Note that regulatory authorities (such as the CNIL) are aware of these technical limitations across SMS aggregators.
