Cold email burns sender reputation, and the damage is permanent. Pipefire moves it onto domains we register, warm and replace, so your company domain stays clean and your invoices keep landing in the inbox.

Measured on our live infrastructure, not projected
Every send adds to a sender reputation score. Bounces, spam complaints and disengaged recipients all count against it. The danger is not that one send fails. It is that your primary domain quietly becomes the one Google and Microsoft no longer trust.
Reputation recovers slowly, if at all. When your domain is filtered, your invoices, contracts and client mail are filtered with it.
Filters do not bounce your mail back. They file it quietly. Your team thinks everything sent, and replies just stop.
Cold email is how agencies and B2B teams fill their pipeline. The fix is to send from somewhere designed to take the damage.
Intake takes about ten minutes. Everything after that runs without you.
Six fields. That is the whole of your involvement in setup.
AI proposes names close to your brand, never identical to it. You approve.
MX, SPF, DKIM and DMARC configured for you, two mailboxes per domain, each on a branded page.
Every mailbox sends and receives on a warming network before it ever contacts a stranger.
Prospects found and verified, sequences written, sending paced like a person. Replies sorted before they reach you.
We register and pay for the domains. You own them, and if you leave they leave with you.
Because cold email damages sender reputation, and that damage is permanent enough to matter. Once your primary domain is filtered, your invoices, contracts and client mail are filtered with it. Pipefire keeps the sending on domains that are designed to be replaced.
In the UK, EU and US, B2B cold email is legal when you identify yourself, provide a working opt-out and honour it. Every message we send carries a List-Unsubscribe header and a visible opt-out, and suppression is enforced before send rather than after.
It is pulled from rotation automatically and a replacement is provisioned, configured and warmed without you doing anything. On Pro and Scale this is automatic; on Standard we do it manually for you.
Yes. They are registered for you and you have full DNS control. If you leave, they leave with you.
Fourteen days on Standard. That is the warmup, and skipping it is why most cold email fails. On Pro and Scale your infrastructure comes from a pool that has already been warming, so the first send goes out the day you sign.
Six fields at intake, then approve the domain names we propose. After that the system runs without you until replies land in your inbox.
Setup takes ten minutes of your time. The first send goes out fourteen days later.
