It's an understatement to say that landing in the inbox is an important consideration every time you send an email campaign. There are 3 domain records important for best inbox delivery: SPF, DKIM & DMARC.
SPF: Sender Policy Framework is used to specify who can send email on your behalf.
DKIM: Domain Keys Identified Mail is used to authenticate each email with a digital signature. When present, our platform signs each email with a unique key.
DMARC: Domain-based Message Authentication, Reporting and Conformance combines SPF & DKIM for authentication & can send error reports.
Most inbox providers check these records & may route to the Junk folder when they fail. GMAIL checks all 3, as shown below.
Use our free tool to instantly check your website & if you need any help to setup, please contact support.
To quickly test the setup in GMAIL, tap the 3 dots on the top right of the message & click 'Show Original'. If setup correctly, GMAIL will show each record as PASS.
SPF only needs to be set up once on your domain. But if you send from several sources, DKIM should be set up for each, because the outbound email server digitally signs each email.
A common mistake is to assume your desktop mail has DKIM. When using a shared hosting service, this is usually not supported. To check, send an email to
firstname.lastname@example.org -in a few minutes, you will get a report with instructions to rectify.
PS These records can help prevent fraud. If your domain is used in a phishing or spoof attempt, inbox providers will route to the Junk folder (when setup correctly).
