Setting up PostMark

First, create an account. Once that’s done, you’ll be guided to set up your email server. You can have multiple servers for different apps, and all you need to do is give each one a name and color for easy identification.

Setting Up Server in PostMark

Before you can send emails, you’ll need to create a ‘Sender Signature,’ which is the ‘From’ address people will see. This needs to be verified to ensure you own it and to prevent spam. After that, you’re all set to integrate PostMark’s API into your web app.
