Definition
Domain warmup is the period during which you send only small, gradual volumes from a fresh cold outbound domain so it earns sender reputation before scaling.
Why it matters
Volume from a brand new domain looks like spam to Google and Microsoft. Domain warmup avoids being blocked before you start.
How it works
- Register the domain and let it age 2 to 4 weeks
- Set up SPF, DKIM, DMARC, and a custom tracking domain
- Create mailboxes and warm each one
- Ramp real sending volume week by week
