Summary
Low Gmail open rates are a multifaceted problem stemming from technical issues like poor email authentication and blocklisting to engagement-related factors such as sending irrelevant content and neglecting list hygiene.

Technical article
Documentation from DMARC.org explains that DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that builds upon SPF and DKIM. DMARC allows domain owners to specify how email receivers should handle emails that fail authentication checks, helping protect against phishing and spoofing and improving email deliverability. Better deliverability directly translates to higher open rates.

Documentation from DKIM explains that DKIM (DomainKeys Identified Mail) provides an email authentication method that allows an organization to take responsibility for a message in a way that can be validated by a recipient. This authentication is used to verify that the message was indeed sent by the domain it claims to be from and that the message content was not altered in transit. This is a key factor in improving email deliverability and open rates.
