How it works

Three steps. You do the first one. We do the rest.

Pick a pack, pay by card

Choose 30 or 100 mailboxes. 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.

We build the boxes

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.

Import and send

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.

Packs

Per mailbox, per month. Quarterly saves 15 %. Domains are extra and at cost, or bring your own.

Talk to us

Domains bought through us: €15 each, one-time, registered in your name and transferable. Prices exclude VAT. 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.

What you get

  • Mailboxes on our own Mailcow servers in Germany, not a reseller tenant
  • SPF, DKIM (2048), DMARC and a tracking domain per domain
  • Per-mailbox limits that keep new domains alive
  • CSV for Instantly and Smartlead, SMTP/IMAP for anything else
  • Forwarding of replies to any address you choose
  • A person on email who fixes things the same day

What you don't

  • Google Workspace or Microsoft 365 inboxes. These are SMTP mailboxes on private infrastructure, the cheapest reliable kind.
  • Warm-up as a separate paid service. Your sequencer already does it.
  • A dashboard. You get a CSV and an email address. A portal comes when customers ask for one.
  • Anyone we would not send for ourselves: adult, gambling, crypto pumps, no website, disposable email. Refunded, no drama.

Questions

Will these land in the inbox?

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.

Why not Google Workspace mailboxes?

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.

Which tools do you export to?

Instantly and Smartlead in one click (their CSV format). Lemlist, Reply, Saleshandy, ReachInbox and anything with SMTP/IMAP settings work with the credentials file.

Do I need to bring domains?

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.

How fast is fast?

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.

What about GDPR and invoices?

Servers in Germany, company in Luxembourg, invoices with EU VAT number. Your data never leaves the EU on our side.

Can I cancel?

Any time, from the receipt link. The paid period runs out and nothing renews. Domains bought through us stay yours.

VC

Built and run by Vlad Centea, AI and infrastructure consultant in Luxembourg. We run our own outbound on this fleet, so the servers get the same care as our own campaigns. Order questions go to hello@outboxes.io and get a human answer within the hour on working days.
