Enter the volume you need to send. This works out the sending domains, the mailboxes on each one, and the daily cap every mailbox holds to — so the whole reachout is visible before a single email goes out.
Why not just send from your own domain
A domain that gets flagged is difficult to recover, and everything your team sends — quotes, invoices, replies — travels on it. acme.com never sends a cold email. It only receives the redirect from each sending domain, so a prospect who types the address in a browser lands on your real site.
A hard ceiling, not an average. Volume grows by adding mailboxes, never by pushing an existing one harder.
Enough to make a domain worth the setup, few enough that losing one domain removes only 45 sends a day.
Authentication is set at purchase, before the first send. An unauthenticated domain is a burnt domain.
Every mailbox signs as the same person, so a prospect who replies twice from different sequences meets the same name.
Sends are spread across the fleet and across the day. No prospect is ever contacted by two mailboxes on the same domain.
All mailboxes forward to a single monitored inbox. The client answers from one screen, not thirty-nine.
