Guides to the parts that decide whether outbound works

Four long-form guides on the questions that actually determine results: which accounts are worth contacting today, why mail gets filtered and in what order to fix it, how to run several mailboxes without damaging a domain, and what it means to run the work layer yourself.

Signal-based prospecting: how to find a reason to write today

Signal-based prospecting means choosing who to contact from dated, public evidence that something changed at their company, rather than from a static list. The signal supplies the reason for the email and the timing; your ideal customer profile still supplies the fit. Fewer messages, each with a defensible opening.

Why cold email goes to spam, and the order to fix it

Cold email lands in spam for five reasons, and they are not equally likely. In order: the domain is not authenticated, the list is stale, recipients are complaining, the sending pattern looks automated, and — last, not first — the copy. Fix them in that order, because the later ones barely matter while an earlier one is broken.

Mailbox ramp and rotation: caps, weights and auto-pause

Running outbound across several mailboxes needs four numbers per mailbox: a daily cap, a weight, a ramp schedule and a health score. Rotation then picks whichever mailbox has used the smallest fraction of what it is allowed today. Everything else — pauses, recovery, graceful degradation — falls out of those four.

Self-hosting your sales data

Self-hosting a sales platform does not have to mean running all of it. The workable split leaves the account and the interface with the vendor and moves the work — sending, crawling, background jobs, model calls — onto a machine you control. Your domain earns its own reputation and your data stays put.
