Excellent email deliverability tool that quickly boosted our inbox placement and seamlessly integrates with HubSpot

Warmy is a stable and intelligent addition to any HubSpot workflow. It protects your sending reputation, keeps deliverability predictable, and removes a ton of maintenance from your email stack. Highly recommended.

What do you like?

Warmy increased our inbox placement very quickly. Connecting our HubSpot senders took only a few minutes and the warm up activity began right away. I like how the tool shows clear percentages for inbox, promotions and spam placement. It feels simple for anyone on the team to understand.

What do you dislike?

The platform could offer more visual comparison graphs for multiple inboxes. It still works well but a cleaner overview would help.

Dramatically improved email deliverability and client communication reliability, though analytics could use simpler explanations for non-technical users

Our communications are far more reliable now, and clients no longer complain about “missing emails.” It boosted both response time and efficiency.

What do you like?

Warmy is easy to understand, even for non-technical teams. It fixed our deliverability issues with client updates, follow-up emails, and intake reminders

What do you dislike?

I’d like more simple explanations in the analytics section for users who aren’t experienced with deliverability
