Don't Blast 10,000 Emails From a Brand-New Domain
A new sending domain plus a big first blast is the fastest way into the spam folder. Warm it up first, and you build a reputation that lands in the inbox for years.
Mailbox providers are suspicious of new domains for a good reason: spammers spin up fresh ones every day. So when your brand-new domain suddenly fires 10,000 emails, Gmail doesn’t see a growing business — it sees a pattern that looks exactly like abuse. The fix isn’t a trick. It’s patience, applied in the right order.
Get the foundation right before you send anything
Before volume even matters, set the table. Use a dedicated sending domain you own, not a shared or free one. Add your DMARC record so receivers know your mail is legit. Turn on email validation so you stop mailing dead addresses. And put a real unsubscribe link in every send. Miss these and even a perfect warm-up won’t save you.

Warm up like you’d train for a race
You don’t run a marathon cold, and you don’t send at full volume cold. Ramp up in stages — a few hundred per hour and around a thousand a day at first, then more as the domain proves itself over the following weeks. Send only to people who opted in and are likely to open, because early engagement is what teaches mailbox providers you’re trustworthy. Plan on roughly four weeks before a domain is properly warm.
Then keep the rhythm
Once you’re warm, two habits keep you there. Send regularly but not erratically — a dead month followed by a giant blast undoes your work. And stop mailing the unengaged: someone who hasn’t opened in 60 days is dragging your whole list’s placement down. It stings to trim, but it stings less than landing the whole list in spam.
The takeaway
If you’re standing up a new domain, resist the urge to import your whole list and hit send. Pick your most engaged few hundred contacts, send them something worth opening, and hold to the volume stages for the first month. Slower at the start is how you go faster — and stay in the inbox — for everything after.
