With all the talk about email mailers that reminds me of a useful tool that came in handy called MailChimp.
When I was building out some email campaigns and needed to run some test deployments I normally send it through a simple and basic mailer I wrote in PHP that sat on my server. The only problem was one day it stopped working or should I say there was a huge delay of 1 - 2 hrs before I received a test deployment of the email.
I jumped on MailChimp and test deployed without any problems. The only issue was the extra footer bar they added with MailChimp branding to the bottom of your code. I'll take that over 1-2 hr delay any day.
