Which email service to use for mass email?

Hi Guys,

This is my first time posting but I have been reading alot of the threads here and so much good information to take down!

I have a question maybe you guys can help me with, I been trying to use mailchimp for mass emails. I never had an issue with them before untill recently when they flagged my account. So I'm looking for another email service to use to send out 5000 emails, do you guy know of a good one to use?


Thank you!

Tony
