Email warmup for cold outbound
Cold email is pointless if it lands in spam. Warm up your mailboxes and protect your domains so your outbound reaches real people.
Cold outbound puts unusual strain on deliverability: new domains, fresh mailboxes and higher volumes are exactly what filters distrust. Warmup is the foundation that makes the rest of your sequence work.
Gradual, human-like warmup
Volume ramps day by day from a safe baseline so mailbox providers see steady, organic growth instead of a spammy spike.
Live reputation scoring
A 0–100 score built from real signals — authentication, bounces, complaints, placement and engagement — so you always know where you stand.
Inbox placement tracking
See whether your test mail lands in Primary, Promotions or Spam, plus SPF/DKIM/DMARC results, before you run a real campaign.
Warm up before you send cold
Launching cold campaigns from a brand-new mailbox is the fastest route to the spam folder and a burned domain. Warm up first so there's a positive history in place.
Pair warmup with clean lists (verify addresses with our email checker), solid authentication, and conservative initial volume to keep complaint rates low.
Frequently asked questions
How long before I can start cold sending?
Give new mailboxes a couple of weeks of warmup before meaningful cold volume, then ramp gradually. Rushing it risks your domain's long-term reputation.
