Catch the mailbox that started landing in spam on Tuesday

Read fourteen mailboxes every Monday

The companion lists the fourteen mailboxes and pulls metrics for each across the last fortnight. The tool takes an explicit from and to as ISO timestamps, so the window is stated rather than inherited. Back comes the one whose landed-in-inbox rate fell away on Tuesday, with the spam count that replaced it.

On a Monday routine that is three lines, plus the remaining quota read from the account tool so nobody discovers the plan ran dry mid-campaign. That is the operations check nobody keeps up by hand, and a routine runs it whether or not anyone remembers.

What can a companion change on an inbox?

Warmup behaviour, and nothing structural.

The update tool covers frequency, language, tags, email topics, extended reply, sender first and last name, schedule and timezone. Every write among them, start, pause, update and delete, requires an explicit confirmation on top of the approval.

Everything credential-shaped is excluded deliberately. SMTP and IMAP settings, Google and Office connections, passwords, token endpoints and ESP priority are changed in Warmup Inbox itself. A tool that can raise daily volume and set a timezone is a tuning knob, and that is what exists here.

• Read: inboxes with status, score, type and tags; one inbox in full; metrics over a date range.
• Read: email templates, tags, and the account’s plan with its remaining quota.
• Write: start, pause, update settings, delete. Each requires explicit confirmation.
• Never: SMTP, IMAP, Google, Office, password, token endpoint or ESP credential fields.

What does pausing warmup cost?

Reputation, while the inbox sits paused.

That is why pausing is flagged destructive and why it waits for you. It is the right call when a mailbox is about to be handed to a real sender or a domain is under review, and a poor reflex when a score dipped for a day. Deleting is permanent.

So the pattern is diagnose weekly and act rarely. The weekly read is where the value sits: warmup scores next to what your outbound tooling actually sent that week, in the same session, so a falling score gets attributed to the campaign that caused it. That is the deliverability half of sales prospecting.

Watch the whole fleet without opening the dashboard

Fourteen inboxes, their scores, their landed-versus-spam split and the quota behind them, read every week without anybody opening the dashboard. Adding a mailbox happens inside Warmup Inbox, where the credential flow belongs, and a companion picks the new one up on the next listing without ever having seen a password.

Templates and tags follow the same pattern: listable here, authored there. The reading is what has to happen every week, and a routine is what makes it happen.
