Incredible solution for email deliverability problems - transformed our spam issues into perfect inbox placement across multiple domains
We found Warmy to be incredibly helpful in addressing our email deliverability issues. It helped us tackle the problem of emails landing in spam and being blacklisted. We initially used it for one domain, and now we're warming up several more. It's been a great tool for improving our email reputation and ensuring better inbox placement
Fast and easy to use
No downsides identified so far

Gradual warmup approach removed delivery uncertainty and stabilized our campaigns, though could use better beginner guidance
The gradual improvement approach stood out to us. Nothing felt rushed or risky. Warmy fit into our existing process without requiring changes to how we plan or send emails.
Warmy helped stabilize our email activity over time. Campaign results became easier to interpret because delivery was no longer a variable.
Some explanations assume basic email knowledge, which may slow down first time users. A short beginner guide inside the platform would help.
