Cold email outreach & infrastructure
The replies are not coming. The usual advice is to rewrite the copy, but most campaigns fail earlier than that — at the DNS records, the warm-up schedule and the send volume.
Deliverability is an engineering problem, and this service treats it as one.

[02]method
Method
Warm-up runs two to four weeks before a single cold email is sent. Anyone who promises sending on day one is planning to burn your domain.
Follow-ups stay in the same thread — a new thread resets the conversation and looks like what it is. Sequences stop immediately on any reply, including an unfriendly one. The first email carries an opt-out line: a GDPR requirement and a deliverability signal at the same time.
