How to send a newsletter from your own domain (and why it matters)
Why sending your newsletter from your own domain improves deliverability and trust, what SPF, DKIM and DMARC do, and how to set it up without the headache.
What "your own domain" actually means
Sending from your own domain means subscribers see email arriving from you@yourbusiness.com rather than from a shared platform address. It is your brand in the From line, and crucially, it is your domain reputation building over time instead of a pooled one you share with strangers.
Why it improves deliverability
Inbox providers decide whether to trust an email partly on the sending domain. Authenticating your own domain with SPF, DKIM and DMARC tells Gmail and Outlook that you are who you say you are, which keeps you out of the spam folder. A shared sender address inherits the behaviour of everyone else using it: a bad actor on the same pool can drag your delivery down.
SPF, DKIM and DMARC in plain English
SPF lists which servers are allowed to send for your domain. DKIM adds a cryptographic signature proving the message was not tampered with in transit. DMARC ties the two together and tells receivers what to do if a message fails. You set these as DNS records once, and they quietly protect every send afterwards.
