What is a sending domain for cold email?
A separate domain that looks like your business, used only to send cold email, so your main domain never carries the risk. If a cold campaign earns spam complaints, the sending domain takes the hit and your main domain, the one your customers, invoices and password resets use, keeps its reputation. Our guide to sending domains covers the full setup.
What makes a good cold email sending domain name?
- Recognisably yours. A prospect who sees getacmeroofing.com should think of Acme Roofing.
- A .com where you can. .com and .net read as ordinary businesses; cheap novelty endings are cheap for spammers too.
- No hyphens or numbers. acme-roofing-1.com looks like a throwaway, to people and to filters.
- Short and plain. Your brand plus a common word such as get, try, hq or team.
How many sending domains does cold email need?
Plan on about two mailboxes per domain and 30 cold emails a day per mailbox once warmed. Ten domains with twenty mailboxes send roughly 600 a day. Spreading volume this way keeps each mailbox looking like a person, and losing one domain never stops the campaign. See how many domains cold email needs.
What do I do after registering a sending domain?
Add mailboxes, publish SPF, DKIM and DMARC, point the domain at your real website, and warm every mailbox for at least two weeks before any cold email. Check the records with the domain checker, and read cold email warm-up before sending.
