What are the best enterprise ESPs? (Our list size is 600K)
We are currently using Maropost and honestly, I'm not very font of it. Our contract is up at the end of the month and I was curious what other people in the industry are using to send Broadcast emails to large lists.
I've been considering Mailchimp Pro, but I've heard mailchimp isn't the best Enterprise solution.
We've also used Listrak in the past and it wasn't the right option for us.
I appreciate any help or insight.
