How long should I warm up a cold email domain?
New domains have no reputation. Warmup is sending small amounts of mail that gets opened and replied to, then raising the cap. Tools can help. They cannot invent a five-year-old domain.
Two weeks is a minimum for many teams. Four is safer if the domain is brand new or the brand is unknown. Copying someone else's 3-day warmup is how you share their bad luck.
Do not warmup and blast the same week at 200 a day. The warmup graph should look like a slope, not a cliff.
Keep bounces near zero during warmup. One dirty list can poison the domain before the campaign "starts."
If the domain already sends customer mail, do not warmup cold on it. Use a sibling domain. See separate domain.
Frequently asked questions
You can skip it. You will learn why people do not. Providers still watch new sending patterns.
No. Different reputations. Warm the LinkedIn seat and the domain as separate jobs.
Aged can help or hurt if it has a spam history. Check it. Age is not innocence.
When seed inboxes land in primary, bounce is low, and you can raise volume a little without a placement crash. Then still raise slowly.
