For any startup creating software, engaging with users is critical. Yet, a common challenge emerges: meticulously designed emails, including vital transactional ones, often land in the spam folder. But, worry not, developers, as we are set to explore the secrets behind enhancing email deliverability.

Email deliverability is essentially the capacity to have your emails arrive in recipients' inboxes.

Email Authentication

To ensure emails reach their destination, it's crucial to use authentication standards like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).

• SPF verifies sender identity by listing authorized IP addresses for email sending.
• DKIM secures emails with a digital signature, ensuring they're unchanged in transit.
• DMARC enhances SPF and DKIM, giving domain owners better control over email authentication and treatment.
• BIMI enables brands to display their logo in recipients' inboxes, provided the emails pass DMARC verification.
