Active Campaign VS Oempro

Hi there.

I would like to find out if there are users out there that use either Active Campaign or Oempro on a large scale basis, meaning as an ESP?

We currently use our own in-house developed software. Its fast and simple. However, it cant be compared against ACEM or Oempro due to lack of some features.

Getting our in-house app re-developed will cost 10x more than just buying AECM or Oempro so I decided to opt in for one of them.

I tested oempro as they offer a trial and have found that it integrates nicely with our MTA software (PowerMTA). AECM does not offer any trial. Yes, I can sign up for a free account but I am not after that. I want to test the stand alone onsite version to see how it can be integrated with PowerMTA. They dont offer that at all.

I am aware of IEM being the best out there. Problem is, we have over 2000 active users, Interspire will charge me an arm and a leg to get a license for that. Oempro seems the most reasonable.

Anybody here that uses ACEM with PowerMTA?

For the replies, I thank you guys in advance
