Find cold email sending domains
Never send cold email from your main domain. Enter it below and we'll suggest close lookalikes (like getacme.com or acmehq.com) and check each one live.
How to pick a sending domain
- Keep it recognisably your brand: a prefix (get, try, hello) or suffix (hq, team, mail) on your name.
- Prefer
.com. Some cheap new TLDs carry poor reputation with spam filters. - Use 2–3 mailboxes per domain and spread volume across several domains.
- Forward each sending domain to your real website so people who visit find you.
