HotHawk
from $97/moOur pickThe best master inbox in cold email, with warmup built into the platform, not outsourced.
Where it wins. Warmup runs natively on a pool of real Google and Microsoft inboxes, with nothing extra to log into. Add the best master inbox in cold email, round robin and mailbox group routing, a white-label ClientBox portal, and a 7-day free trial.
The trade-off. HotHawk costs more than the budget tools, it does email outreach only, and there is no built-in lead database, so you bring your own leads. We focus on the sending and the replies.
