How do I warm up a brand-new sending domain?

Warming up means slowly increasing how many emails you send so inbox providers learn to trust you. Skip it and you'll land in spam fast.

Here's a simple 30-day plan:
—
1. Days 1-7: send to your 20-30 most engaged people only (folks who opened recently).
—
2. Days 8-21: double your send volume every few days, always picking openers first.
—
3. Days 22-30: add the rest of your list in batches, watching for spam complaints.

✅ Cap your very first send at 50 emails, no more.

Homework: Write down today's date plus 30. That's your full-speed day.
