Cold email infrastructure, provisioned in minutes.

A fully provisioned sending mailbox on our SMTP infrastructure: SMTP and IMAP access, full authentication (SPF, DKIM, DMARC, MX, reverse DNS). Sending is not metered per email — the mailbox price covers it. Domain registration is the only separate cost, and we pass that through at registrar price.

Because one or two mailboxes is not a working cold-email setup. Modern filters reward low, steady volume per sender, so real campaigns spread sends across several mailboxes rather than pushing one hard. Five is the smallest footprint where the numbers actually work — and it keeps our IP pools populated with genuine senders.

Yes. Mail leaves through outbound nodes and IP pools we operate, under our own queue and throttling policy — not a consumer mail account wrapped in a dashboard. That's what lets us segment senders by reputation, control throttling, and fix a deliverability problem at the source instead of filing a ticket with a third party.

We recommend 30–50 per mailbox per day, which is the range that holds up well against inbox providers. With a brand-new mailbox, start lower and build up over a couple of weeks. Ten mailboxes at a safe rate is 300–500 sends a day — that is why slots, not send quotas, are the unit we sell.

Add slots any time from the dashboard at a flat $3.50 each on any plan — no plan migration needed. New slots prorate from the day you add them. You can also release slots; they stay available until the end of the billing period you've paid for.

Yes. Point the domain's nameservers at our grid and we'll generate and validate every record needed for sending. A word of caution: if a domain is also your main company website, keep cold outbound on a separate domain so a reputation hit can never touch your primary brand.

You do. Domains are registered to you, and you can transfer them out whenever you like. We never hold a domain hostage to a subscription.

Mailboxes on a connected domain are usually live in under ten minutes. A freshly registered domain can take a little longer while DNS propagates — typically well under an hour. You'll see a live status per mailbox in the dashboard and get a notification when authentication passes.

If it accepts SMTP credentials, yes. For Smartlead, Instantly, Reply.io, Lemlist, Apollo, Salesforge, HubSpot and Woodpecker we also generate a ready-to-import file in that platform's exact CSV shape, so connecting a full batch of mailboxes is a single upload.

Pause the mailbox from the dashboard or move the sender onto a different domain — and our team will look at the underlying IP and queue behaviour on our side.

No setup fee and no contract. Billing is monthly and you can cancel from the dashboard. Domains you purchased remain yours after cancellation.

Purchased or scraped junk lists, phishing, malware, adult content, and anything that violates CAN-SPAM, GDPR or your local equivalent. We monitor complaint and bounce rates and will suspend accounts that damage the pool — that enforcement is precisely what keeps deliverability good for everyone else on the grid.
