The whole loop, in six steps

From your own mailbox to a booked meeting.

Nothing here is rented from us. You connect inboxes you already own, warmup starts the same day, and every reply comes back to one place with a status already on it.

unlimited mailboxes on every plan
warmup included, never a separate bill
01

Connect your inbox

Gmail and Outlook go in over OAuth in two clicks. Google Workspace and Microsoft 365 the same way, or with an app password. Anything else goes in over IMAP and SMTP.

Bring your leads

Bring the list you already have, or describe your ideal customer and let the Lead Generator build one. You see a sample and what it costs in credits before it runs.

Write the sequence

Steps with A, B and Z variants, spintax for the lines you repeat, and conditions so a step only goes out when it should.

Set the sending rules

Pick the days, the hours and the timezone, or take a preset. Your mailboxes take turns inside that window, so no single inbox carries the whole campaign.

Running underneath all six steps

Warmup never stops, and it is never a separate bill.

Auto-inbox starts the day you connect a mailbox and keeps going while your campaigns run. Real conversations with real inboxes, with a placement score you can check before you launch.

Launch

The campaign starts at the next open window and works through the list at the pace you set. From here you are not sending mail, you are reading answers.

Work the replies

Every answer lands in the Unibox, sorted into Lead, Interested, Meeting booked, Meeting completed, Won or Not interested, with sentiment and how urgent the Insight Agent thinks it is.
