When you first log in, you’ll need to head over to the Configuration tab, located at the top of the page. This is where we’ll spend our time setting up the Sparkpost account.
We’ll need to set up a domain for sending emails. Make sure you have the “Sending Domains” tab selected (shown in the picture below). Click the “Add a Domain” button, found in the top right of the page.
NOTE: For testing, I used sparkpost.aperturescience.dev, however you should not be required to use sparkpost as a subdomain.
