I use MailerMailer myself and it just seemed however to me that many of my emails were not getting to the people. I dont know if there was something on my end so I just stoped and have not sent out email in over a year.
I do love their setup though and its so damn easy. Thats why I still paid them for the year even though I have not used them.
I still am not sure what to do about my email issues but in the next few weeks I hope to find out.
Ahh but yeh my whole point of the post was jsut to say mailermailer is solid!
