I have legit lists but open rates keep dipping with my current ESP. This is puzzling because bounces are low and complaints are next to none. The only thing I can think is my own poor segmentation and rotation of sending. I also have ses and send grid. But it's such a pain to set it all up on something reliable. I'd like to segment better so that I can mail break up my lists and mail from my esp, sendgrid, and ses. Can you setup a system for me that's as turnkey as possible? Or help me get to the bottom of this? Hit me up with a proposal.
