The SMS by MESA app is a great way to quickly send SMS messages. However, if you need to send international messages or send a high volume of messages, we recommend using the Twilio app to send messages from a dedicated phone number you control. Twilio charges a monthly fee to purchase the phone number (typically $1 per month) and a per-SMS fee (typically around a cent per message).
Connect Twilio with MESA
Before you get started, you will need to create a Twilio account, add your billing information, and purchase a phone number in the Twilio console.
When you're setting up your first workflow with Twilio, you'll need to add your Key and Secret so that Twilio is a connected app within MESA.
You can click here to locate your Account SID and Auth Token. Within the Twilio Settings, click on the Keys & Credentials: API keys & tokens section.
In the Live Credentials section:
- Copy the Account SID and paste that as the Key within MESA.
- Copy the Auth Token and paste that as the Secret within MESA.
Then, click on Add Credential and then you are all set!
In order to send a SMS, you will need to add a phone number into the From phone number field. Make sure that the phone number that you enter does not contain dashes or parenthesis but do contain a country code. An example: +15017122661
In the To phone number field, you can utilize variables to make the SMS action specific to your needs. The screenshot below is from the Send an SMS via Twilio to your customers when their order arrives template.
