What is your feature/integration request?
When using SendGrid as your final destination, give the user the ability to either 1. Preview the html with merge tags or 2. Send a single test email to a email address given by the user.
What problem would this feature/integration solve?
This would allow the user to test/view the email (with real data from parabolas merge tags) before sending to potential thousands of recipients.
How do you solve/workaround this problem today?
Right now I add myself to the list, create a temporary row filter to make me the only recipient, then burn multiple credits to see the final result.
