Before you send anything
- Set up SPF, DKIM and DMARC and check them with our SPF & DMARC and DKIM tools.
- Make sure your domain and IP aren't already on a blocklist. Recycled IPs sometimes are.
- Let the domain age a little. Mail from a domain registered yesterday is suspicious by itself.
- Clean your list: remove bounced addresses and anyone who hasn't opened in a year.
How fast to ramp up
A careful plan starts with 20–50 emails a day and grows by about 15–25% a day, reaching full volume in four to eight weeks. Our email warmup planner builds a day-by-day schedule from your target volume and provider limits, with a CSV you can follow.
Send your most engaged contacts first: people who opened or clicked recently. Early replies, opens and "not spam" clicks build reputation fastest.
Keep it steady
- Send every day, at similar times. Big gaps followed by spikes look like a spammer.
- Don't jump ahead of the plan even if things look good.
- Mix in personal one-to-one mail, which gets replies.
What to watch
- Bounce rate below 2%. Higher means the list is old or bought.
- Spam complaints below 0.1%, and never above 0.3%.
- Google Postmaster Tools shows your domain's reputation at Gmail once you send enough volume.
If numbers go the wrong way, slow down or pause for a few days rather than pushing through.
