- Question
- How do I warm up a new email sending domain?
- Direct answer
- Start with 20 to 50 sends per day to your most-engaged recipients (people who opted in recently or replied recently). Double daily volume weekly until you reach your target send rate, typically over 3 to 6 weeks. Set up SPF, DKIM, and DMARC records before the first send. Sending high volume from a cold domain on day one will land your emails in spam permanently.

What's the nuance?
Engagement signals (opens, clicks, replies) build sender reputation. Send to subscribers who actually engage; skip the dormant ones during warm-up.
What else should I know?
Transactional emails (welcome, receipt) build reputation faster than marketing broadcasts because they're high-engagement. Send them first if your stack supports it.
What's the common mistake here?
Subdomain strategy isolates risk. Use mail.yourdomain.com for marketing and updates; transactional comes from app.yourdomain.com. If marketing tanks reputation, transactional stays clean.
