SPF is a DNS record that lists which servers may send email using your domain name.
Receiving servers check it. If your email comes from a server not on the list, it lands in spam or bounces. Google and Microsoft now insist on it.
SPF lives as a TXT record on your domain. Like MX, it has nothing to do with your website and must survive a website change untouched.
Our go-live checklist reads your SPF record before we start and confirms it after. Nothing about a Think Bright Sites launch should change it.
DKIM adds a digital signature to your outgoing email so receivers can prove it was not altered.
DMARC is a DNS record that tells receivers what to do with email that fails SPF or DKIM checks.
An MX record tells the world which server receives email for your domain.
DNS is the phone book that turns your domain name into the address of the server that holds your site.
