HotHawk
from $97/moOur pickThe best master inbox in cold email, with white-label included rather than charged per client.
Where it wins. Unlimited client workspaces and full white-label with ClientBox, included rather than billed per client. Plus the best master inbox in cold email, round robin and mailbox group routing, warmup on real Google and Microsoft inboxes, and replies that surface in real time, all in one reliable tool.
The trade-off. You bring your own leads and mailboxes, so there is no built-in lead database, and HotHawk does email outreach only, not multichannel. We focus on the sending and the replies, not prospecting data.
