Access you scope, mailbox by mailbox

Your agent sees only the mailboxes you choose.

  • Connect Claude, Grok or any MCP agent with one sign-in.
  • Pick what it can do in each mailbox.
  • Its replies can wait as drafts until a person approves them.
  • Every action is logged, and unverified email stays hidden from it.

Every company in one inbox

No more one Gmail tab per company.

  • Every address in one sidebar, with its own unread count.
  • Replies go out from the address that got the email.
  • Instamp shows the DNS records for each domain and checks them.
  • Folders like Gmail labels, plus Snooze and Sent.

Your team and your agents, in the same mailboxes

Hand work to a person or to an agent.

  • Each person sees only the mailboxes they need.
  • Assign a conversation to a teammate or an agent.
  • Internal notes never reach the customer.
  • Replies, assignments and drafts update live.
