inboxing 101

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. And from February 2024, Gmail makes this mandatory.
