Hosted outbound · your domain

Turn every first email into a reply — without buying a spam folder.

One app, many workspaces. DNS has to pass before launch. A reply halts the sequence. Bounce above 3% pauses the inbox. You send from your SMTP — never a shared warmup pool.

Product

The workspace is a table, a timeline, an inbox, and a board.

Inbox

The first reply cancels the rest.

Stop-on-reply is not a preference. The worker cancels remaining sends the moment a thread comes back. Interested becomes a deal. Unsubscribe stays suppressed on the next import.

This is useful — can we do 20 minutes Thursday? I will bring our head of security.

Halted. 3 remaining sends cancelled.

Launch

Launch is a lock, not a button.

The campaign stays locked until DNS passes, the list is under 3% bounce risk, and every email step carries the unsubscribe token. The lock always says why, and where to fix it.

List

A dirty list spends the domain.

Apollo, Clay, Instantly, or a CSV. Suppression survives re-import. The clean gate is 3%. Above that the list is not launchable — orange if you are close, red if you already bought spam.

Sequence

If the token is missing, it is not ready.

Every email step must include {{unsubscribe_url}}. Wait steps hold the queue. The timeline is the editor — one sequence, one status chip, no second canvas.

Interested becomes a deal. Lost is a stage.

A positive reply opens a card. Meeting needs a URL. Won and Lost are terminal. The board is the record — not a feeling in a spreadsheet tab.

Timing

Method

Deploy the loop. Then keep it honest.

Six steps, in order. Skip one and the lock stays shut. That is how a cold inbox stays out of the spam folder.

01

ICP

Who you sell to, written down before the list exists.

02

Inbox

Your SMTP and IMAP. DNS must pass before the first live send.

03

List

Apollo, Clay, or a CSV. Suppression survives re-import. Clean gate is 3%.

04

Sequence

Every email carries {{unsubscribe_url}} or it is not ready.

05

Launch

Blocked until the list, sequence, and inbox are all green.

06

Replies

Stop-on-reply cancels the rest. Interested becomes a deal.

ICP, inbox, list, sequence, and launch return to replies.

The box

Shared workers. Isolated data. Your SMTP only.

Workspaces share the app and the queue, tagged by workspace id. There is no shared IP and no sending from ours. When DNS on your domain passes, you send from the address you already own.

Invite one teammate. Import a list. Launch stays locked until DNS, the list, the sequence, and a postal address are honest.
