Domains and mailboxes provisioned inside Pipe Crush, warmed up automatically, and replaced the moment deliverability drops. Stop configuring DNS and watching blacklists — buy capacity, not plumbing.
Connect the accounts you already have for free — or protect your main domain with dedicated warmed mailboxes, spun up in a single click.
Connect the email accounts you already own and send sequences from them at no extra cost. Great for warm outreach and replies — but every cold send happens on your own domain's reputation.
Cold outreach can put your primary domain's reputation at risk. Spin up dedicated mailboxes on a separate warmed domain instantly — one click, no DNS work — and keep your real domain clean while you scale sending.
One bundle is everything you need to run a real cold email sending lane — provisioned inside Pipe Crush, not bolted on from a separate tool.
A domain reserved for your cold outreach, kept separate from your primary business domain so a deliverability issue never touches your main inbox reputation.
Four mailboxes on that domain, provisioned and connected to your sequences automatically — ready to send as soon as warmup clears them for volume.
Warmup runs as an automatic, health-driven background process for every mailbox in the bundle. There is no warmup toggle and no separate warmup SKU to buy.
Everything happens inside Pipe Crush — no separate vendor accounts to manage, no DNS records to copy by hand.
From purchase to your first send, in three automatic steps.
Add a Sending bundle from your dashboard — 1 domain and 4 mailboxes, live in minutes. No DNS records to copy, no registrar accounts to juggle, no manual setup.
Every mailbox ramps through a health-driven warmup schedule — about 15 automated warmup emails a day per mailbox — before your first campaign send, then settles into maintenance mode for as long as it stays healthy. Once warmed, the deliverability-recommended pace is ~15 cold emails a day per mailbox, and a hard 100/day safety limit is enforced automatically so a mailbox can never be burned by oversending. Warmup is included and always on — never a toggle, never a separate purchase.
If a mailbox's health drops or it lands on a blacklist, Pipe Crush automatically re-intensifies warmup or replaces the mailbox with a fresh one. No manual monitoring, no scrambling to fix deliverability yourself.
Each mailbox in a bundle handles about 15 cold emails a day at a healthy, sustainable sending rate. Across 4 mailboxes, that's real monthly volume.
One price per bundle. Your plan tier sets how many bundles you can buy — no overage billing, ever.
1 domain + 4 warmed mailboxes, billed as a recurring add-on subscription and prorated when you add or remove bundles.
Hard caps with upgrade prompts when you reach your tier limit — no overage billing.
We disclose the full lapse policy up front — no surprises if a payment fails or you cancel a bundle.
Everything keeps working. Recovering your payment method inside this window is fully reversible with no impact to sending or warmup.
Outbound sending from the bundle pauses, but warmup keeps running so mailbox health does not decay while you resolve billing.
Warmup activity for the bundle stops. Reactivating after this point restarts the mailboxes at an earlier point in the warmup ramp.
The domain and mailbox slots are released back to the pool. Any inbox data already ingested is retained under Pipe Crush's normal data retention policy — it is not deleted.
