Warmed mailboxes. Deliverability as a service.
Domains bought, SPF/DKIM/DMARC configured, mailboxes warmed for 14 days, rotated automatically — all for $4/mailbox/month + $14/domain/year. The email infrastructure that powers Happierleads outreach to the visitors we identify — and the one piece of the stack that works on its own if you already have a list and just need a clean place to send from.
Buy only what you need. Scale up or down any month. No lock-in. Works with Happierleads or on its own.
Three problems we solve — so you don't have to
Setting up a reliable cold-email stack used to mean Namecheap tabs, Google Workspace billing, DNS records, and a warm-up bot you didn't fully trust. Happierleads runs the whole stack for you — at a transparent price.
Domain & DNS
We buy the lookalike domains, configure SPF, DKIM, DMARC, MX, redirects — and point a branded tracking domain to each mailbox.
Mailbox provisioning
Google Workspace or Microsoft 365 mailboxes spun up on demand, 2FA-ready, pre-connected to the Happierleads sequencer.
14-day warm-up
A private warm-up network ramps each new mailbox's volume gradually — opens, replies, folder-moves — before it ever touches a prospect.
Size your cold-email infrastructure
Pick the number of domains and mailboxes you need. Cost transparent, no bundled nonsense.
How many mailboxes do you need?
Tell us how many contacts you want to reach every month. We'll buy the domains, provision the mailboxes, warm them up, and plug them straight into your sequencer — so you can send at scale without burning your main domain.
Your outreach volume
Contacts you want to email per month (across all sequences).
Each mailbox sends ~30 emails/day safely. We spread load across mailboxes and keep domains small to protect deliverability. How Inbox Engine works →
Or $268.00/year — domains billed annually, mailboxes monthly.
No long-term contract. Cancel anytime. Domains you keep.
We configure authentication on every domain so you land in inboxes — not spam.
Every mailbox is warmed for 2–3 weeks before first send. No extra fee.
Works with Happierleads Sequencer, Smartlead, Instantly, Lemlist & more.

DNS, domains, mailboxes — all wired correctly.
A mis-set DMARC record is the difference between landing in the primary inbox and the spam folder. Every piece of infrastructure we ship is configured to Google and Microsoft's latest requirements, audited on creation, and re-verified weekly.
- check_circleLookalike domain procurement. We register variants of your primary domain — acme.io, getacme.com — so you protect your main brand's reputation.
- check_circleSPF / DKIM / DMARC. Configured to pass Google & Microsoft DMARC 2025 requirements on day one.
- check_circleBranded tracking domain. Every open / click goes through your own subdomain — not a shared tracker blacklisted by spam filters.
- check_circleMX + catch-all routing. Reply routing, catch-all inboxes, auto-forwarding — set up without you touching a DNS record.
14-day warm-up that actually earns inbox reputation
Our warm-up network sends, opens, replies and moves-to-primary across thousands of real mailboxes for 14 days — so your inbox has earned its reputation before it touches a prospect.
- check_circleGradual ramp. Day 1 sends 5, day 14 sends 40 — no cliff, no throttle hits.
- check_circleReal open + reply signals. Peer mailboxes open, reply, and move to primary — the same behaviour Google's spam filter rewards.
- check_circleContinuous maintenance. Warm-up doesn't stop at day 14 — it runs in the background forever, keeping reputation above water.
- check_circlePostmaster integrated. We watch Google Postmaster + Microsoft SNDS for each inbox, and reduce sends automatically if reputation dips.
One campaign, many inboxes — reputation preserved.
Sending 5,000 emails from one mailbox will melt it. We spread a single campaign across every warmed mailbox you own — so each inbox stays under safe daily limits and no single domain takes the heat.
- check_circleAutomatic rotation. Happierleads decides which mailbox sends next, based on its warm-up status and health.
- check_circlePer-mailbox daily caps. Set or accept our defaults — 30 / 40 / 50 depending on age.
- check_circleSignature parity. Every rotated mailbox sends with consistent signature, tracking, and unsubscribe.
- check_circleFallback on reputation dip. If one mailbox's reputation drops, we pause it and shift sends to healthy ones.
Every reply, every mailbox — one view.
Fifteen mailboxes only become a problem when you have to check fifteen inboxes. We fold them into one universal reply view — triage, assign, and book meetings without switching tabs.
- check_circleAll mailboxes, one view. Replies, bounces, out-of-office, auto-classified.
- check_circleMeeting booking inline. Calendly and Google Meet links inserted automatically; replies trigger booking.
- check_circleAI classification. Interested, objection, not-now, unsubscribe — tagged and routed without rules.
- check_circleCRM logging. Every thread written to HubSpot or Salesforce as a native activity.
