Connect Mailgun with MESA

When you're setting up your first workflow with Mailgun, you'll need to add your API key so that Mailgun is a connected app within MESA.

From your Mailgun account dashboard, click on your profile from the top right hand corner and then click on API Keys.

Next, click on the eye icon next to Private API key. Copy and paste it in the API Key field.

Once the API Key is entered, click on Add Credential to connect MESA with Mailgun! Lastly, click on the Done button and hit the Save button at the top of or below the workflow to save your changes.


Select your Domain

All Mailgun Triggers require you to select a Mailgun Domain that MESA should work with. Click on the Domain drop-down menu and select your domain. 

🗒️ Note: After saving the workflow for the first time, the domain selected in the Trigger cannot be changed. If you need to change the domain, please create a new workflow.

Once selected and after ensuring that you have selected the correct domain, hit the Save button at the top of or below the workflow to save your changes.
