The honest take

Where it breaks

Warmup builds reputation but cannot rescue spammy content, purchased lists, or broken authentication. It is one piece of a deliverability stack, not a standalone fix.

The verdict

Mailwarm is a focused, well-rated email warmup utility for cold senders and agencies protecting deliverability. Its G2 base is small but positive; treat it as a complement to a sending stack with sound list and authentication practices.
