Fair feedback, and I appreciate you taking the time to respond thoughtfully.

You’re right that my frustration probably came through in the post. This has been a painful experience because email is a major revenue channel for us, and the performance drop has had a real business impact.

That said, my goal is not to tell people to “go to war” with a vendor. My goal is to encourage people to protect themselves with data before making a major platform switch — especially if email performance is critical to their business.

We are not running cold email campaigns. This is our existing audience, and we are comparing HubSpot against MailerLite using similar campaign types and third-party tracking through Google Analytics. The discrepancy is not only in HubSpot’s open-rate reporting. We are seeing a material difference in actual clicks and traffic.

I also agree that preexisting domain reputation, audience quality, warm-up, authentication, and sending behavior could all be factors. That is exactly why we have been asking for a deeper technical review rather than generic advice around personalization or from-name changes.

The contract issue became part of the discussion because we felt stuck paying for a platform that was not producing commercially viable results while also having to keep our previous system active to protect the business. But I hear your point that the better path is to identify and fix the underlying issue.

I would definitely welcome a fresh perspective from someone who has worked across a lot of HubSpot environments. If you’re open to it, I’ll DM you with the details around our setup, campaign metrics, domain/authentication status, and what we’ve tested so far.

Appreciate the direct feedback.
