Email Tag Selector - Previously Used Emails

Problem: Users regularly used the same email or emails for testing purposes and they have to type those email every time they’re testing their email campaigns.

Solution: This proposal allows our users to select previously used emails in a simple way.

The previously used email or emails will be saved as string values allowing a maximum number of 3 strings, users will be able to select between these strings.

Among other features we have if there are no previously used emails then there would be no need to show these UI elements and that when selecting one of the strings, whatever is in the textarea would be replaced.
