You’ve been invited to test an app for the Amazon Appstore, but the developer has informed you that your Amazon Account is opted out of Amazon marketing communications so your invitation email never arrived.

Here’s how to opt back in to just the one category Amazon requires so you can proceed with the test.

Click on this link.

Expand the dropdown next to “Promotional Emails” in “Email Preferences”

Make sure “Amazon Appstore” is checked and click “update”.

Let your developer know and they’ll send you a new testing invite.
