Just when you have the website designed and the content ready to go live, your client wants to add a monthly or weekly newsletter.
What platform do you use to generate yours?
I have used Editize, Constant Contact, and Mail Chimp.
MsWord and Open Office (or Libre Office) each also have mail merge capabilities and some web hosts have a default you can use in your hosting account.
What features do you like best about the one you use and what improvements would you like to see in it?
