Cold Email InfrastructureReady In Minutes

Create hundreds of domains and mailboxes using a distributed email infrastructure with excellent deliverability and free automated setup. Cold outreach made easy!

Your sending infrastructure

The sending layer behind your cold outbound

Domains, mailboxes, DNS and warmup, run as managed infrastructure. You pick the quantity; we keep it landing.

Provisioning

Domains, mailboxes and DNS, set up on day one

Pick a mailbox count and we do the rest: lookalike domains sourced and bought, mailboxes created and configured, and SPF, DKIM, DMARC and tracking DNS set on every domain before a single send goes out. What used to be hours of setup per client happens without you touching a registrar or a DNS panel.

Warmup

14–21 days of warmup before anything goes live

Every mailbox ramps on its own schedule — volume climbing daily, replies and engagement building the sending history that inbox providers actually look at. Nothing is handed over until the fleet has a reputation worth protecting, so your first real campaign lands on domains that have already earned their place.

Isolation

Dedicated IPs, so nobody else can burn you

Every customer gets their own dedicated sending IP, their own DKIM signing key, and their own bounce and tracking domains. No shared IP pool, no neighbour blasting 10,000 sends a day off your address, and no way for someone else's bad list to sign as you. The reputation objects receivers score are earned by your sending and nobody else's.

Monitoring

Watched across 90+ blacklists, around the clock

Every domain and IP is checked against 90+ blacklists on a rolling cycle. The moment a mailbox's reputation dips, it is paused automatically and a fresh, warmed domain is swapped in — no burned domain keeps sending, and no campaign stalls waiting on a manual fix. Enforced sending caps stop a runaway sequence from burning a domain in the first place.

Handover

Logins that paste straight into your sequencer

When warmup completes, you get the lot: mailbox logins with IMAP and SMTP details, exported in the shape Instantly and Smartlead import natively. Connect the accounts, load your sequence, and send — no DNS spelunking, no credential spreadsheet assembled by hand, no setup call required.

Why it holds up

Every mailbox, monitored

Deliverability is not a setup step, it is an operations job. Your fleet sends and signs as nobody but you, is watched across 90+ blacklists, and pulled out of rotation the moment anything dips — before a burned domain takes a campaign down with it.

90+ blacklistsDedicated IPsEnforced caps

Dedicated IPs, never shared

Your fleet sends from IPs nobody else touches, signs with your own DKIM key, and bounces and tracks on your own domains. There is no shared IP pool to inherit a bad reputation from — if your sending is clean, your deliverability stays yours.

Blacklist monitoring, around the clock

Every domain and IP is checked against 90+ blacklists on a rolling cycle. A listing is caught within hours, not discovered a week later in your reply-rate graph.

Auto-pause and domain swap

The moment a mailbox's reputation dips, it stops sending automatically and a fresh, warmed domain is rotated in. A burned domain never keeps quietly torching your campaigns.

Sending caps, enforced

Per-mailbox daily caps are enforced at the server, not suggested in a doc. A misconfigured sequence physically cannot blast a warming domain into a blacklist.

Who we help

Built for teams that send at volume

Agency founders

Lead-gen agencies running many clients

Every new client used to mean hours of domains, DNS and mailbox setup before a single send. Order the quantity, hand over warmed logins two to three weeks later, and keep your margin on the retainer rather than on registrar admin.

Agency ops

The people who keep campaigns sending

One dashboard for every client fleet: what is warming, what is active, what got paused and what replaced it. When a domain burns you find out from us — with a warmed replacement already rotating in — not from a flatlined reply rate.

SaaS outbound

Heads of outbound scaling volume

Send from lookalike domains on infrastructure that is completely separate from your product and your corporate domain. Scale to hundreds of mailboxes without your primary domain's reputation ever being on the table.

SDR teams

Teams living in Instantly or Smartlead

The logins arrive in the shape your sequencer imports natively. Connect accounts, load the sequence, send — capacity per rep becomes a number you order, not a project you scope.

FAQ

Frequently asked questions

Can you migrate us from another provider?

Yes, free. We move your existing domains and mailboxes across, re-point DNS, and keep sending history intact where the provider allows it. Anything too burned to keep gets replaced with fresh, warmed stock as part of the switch.

Who owns the domains?

You do. Domains are bought on your behalf at a flat £10 a year each. If you ever leave, they transfer out with you — your sending reputation is an asset you keep, not a hostage.

How long does warmup take?

14 to 21 days, depending on how the mailboxes respond. Volume ramps daily and nothing is handed over early — a fleet that skips warmup lands in spam, which defeats the point of paying for infrastructure.

What happens when a domain burns?

It is paused automatically the moment monitoring catches the dip, and a fresh, warmed domain is swapped into your fleet. You keep sending on the healthy remainder; the replacement joins rotation as soon as it is ready.

How does cancelling work?

Billing is monthly and you can cancel any time. Your domains transfer to you on the way out, along with the mailbox credentials — no lock-in, no exit fee.
