Deliverability

Real warmup, built in. Not a separate bill.

  • Every inbox warms up on its own schedule so your real campaigns land in the primary tab.
  • An honest health score tracks placement and trend, and flags a dying inbox before it tanks your domain.
  • No shared warmup pool gimmicks. You build a real sender reputation on inboxes you own.

Reply management

One inbox for every reply, sorted by AI.

  • Replies from all your mailboxes land in one place, not scattered across tabs.
  • Each reply is read and labelled: interested, meeting, out of office, not now.
  • The hot leads sit at the top, so you spend your time only where it counts.
