If you're like me (or Mark), you like to test each campaign you send fairly comprehensively before you send to your complete subscriber list. In my workflow, this usually involves firing the email off to a number of test accounts I've set up at various ISP's like Hotmail, Yahoo! and Gmail.
I always found it a little annoying come testing time when I'd have to remember each of these test addresses. Sometimes it wouldn't arrive and I'd have to double check the address and re-send. Not a deal breaker, but it was definitely annoying. Turns out this was an annoyance a number of customers also had. Today, we did something about it.
From now on we'll remember the last 5 test email addresses you used for that particular client. Often this might be a contact at the client, and a few of your favourite test addresses. Simply tick the checkbox next to the addresses you'd like to send a test to and we'll do the rest.
