ACYMailing for WordPress

i have used pretty much all the built in WordPress plugins for various clients – Mailpoet, plugins for Constant Contact or Mailchimp etc. but ACYMailing is the best of them all. Direct integration with WordPress features, so it’s a cinch to create relevant newsletters with current post information and much more. The integration with third party (free) bulk mail like Sendgrid and Elastic Mail (and the rest) is also first class. I recommend it highly,
