How to bring up a snowballing open rate

Excellent post @paxton. Thanks for that.

Would you guys have any info on the impact of sending to those same unengaged contacts using the same email domain, but from another platform?

We’ve heard tale (from a Vertical Response user) that they beat HubSpot open rates by sending from another platform (using the same email domain). However, this flies in the face of everything we’ve ever read (or heard) about how email domain reputation follows from platform to platform.

Any news would be greatly appreciated. Thanks again.
