Which Email Authentication Should I Set Up?
SPF, DKIM, and DMARC are three complementary email authentication standards that together protect your domain from spoofing and improve deliverability. This tree guides you through which records to publish and in what order, based on your DNS access and sending setup.
निर्णय के चरण
Do you have access to publish DNS TXT records for your sending domain?
Have you already published an SPF record (v=spf1 ...) for your domain?
Does your email sending service (ESP or mail server) support DKIM signing and provide a public key?
Have you published the DKIM public key as a DNS TXT record at selector._domainkey.yourdomain.com?
Do you have a DMARC policy record published (v=DMARC1 at _dmarc.yourdomain.com)?
Is your current DMARC policy set to 'none' (monitoring only, no enforcement)?
