How to send verification emails using other mailing services instead of using Bubble's inbuilt SendGrid

I need help on how to implement sending of verification emails using a different mailing service instead of using SendGrid which is required by Bubble. Any advice will be appreciated.

Which is your preferred provider?

I would love to use Postmark instead. From the images attached, it seems Bubble is limiting sending of verification emails to SendGrid. If you have any idea on how I can add a Postmark API key instead, don’t hesitate to tell me.


We use postmark on almost all of our apps. It’s the best!

Also, it’s really simple to integrate, when you’re done creating a template with all variables and other things on postmark, just click on “Get Code” then copy the code they give for cURL and paste that in API connector through “Import another call via API” and set the “use as” as action.

You should be able to take it from there!

Thank you so much for your help!!
