Unlimited mailboxes, priced per domain. DNS, DKIM and DMARC done for you, a CSV that drops straight into Instantly or Smartlead. No platform fee, cancel any month.
Three steps. You do the first one. We do the rest.
Choose how many domains, or the agency flat rate. Bring your own domains or let us buy them at cost. Tell us your sender names and which tool you use at checkout, and that is all we need.
Domains pointed, SPF, DKIM and DMARC set, tracking domain, sane per-mailbox sending limits, forwarding to your inbox. Three mailboxes per domain, the way deliverability people recommend.
You get a CSV in the exact format of Instantly or Smartlead, plus SMTP/IMAP details for anything else. Warm-up runs in your sequencer, so you pay for it once, not twice.
Unlimited mailboxes. You pay per domain, up to 5 mailboxes on each. Agencies pay one flat rate. Domains are at cost, or bring your own.
Domains bought through us: €15 each, one-time, invoiced after we check your order, registered in your name and transferable. Prices exclude VAT; EU businesses with a VAT number are reverse-charged at checkout. Cancel any time from the link in your receipt; the current period runs out, nothing renews you silently. Refused orders are refunded in full within the hour. "Unlimited" means mailboxes, never sends: per-mailbox limits protect the IPs everyone shares.
Fresh domains on clean IPs, correct DNS and sane limits get you the same starting point as any provider. What happens after that is your list and your copy. We do not promise open rates, and we replace a burned domain once a quarter on the 100 pack.
They cost two to three times more and Google is tightening on cold email every quarter. SMTP mailboxes on private servers are what most agencies run at volume now. If you specifically need Workspace, we are not your provider.
Instantly and Smartlead in one click (their CSV format). Lemlist, Reply, Saleshandy, ReachInbox and anything with SMTP/IMAP settings work with the credentials file.
No. Tell us how many and we buy them at cost, €15 each one-time, in your name. Or bring your own and point the nameservers to us; we tell you exactly what to enter.
Order before 14:00 CET and you are sending the next working day. New domains still need warm-up in your sequencer before real volume, usually two weeks, like everywhere.
