Email authentication - Understanding headers

Pierre-Yves Dubreucq — Thu, 11 Jul 2024 08:33:10 +0000

Email authentication is crucial to ensure your emails reach recipients’ inboxes, especially for transactional emails where errors are unacceptable. The main methods of authentication include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance).

To verify these configurations, examine the email headers for specific elements. Understanding these details will help you improve your email deliverability and security.

1. SPF Header

Received-SPF header indicates the result of the SPF check performed by the receiving server, and the Authentication-Results header indicates the result of the SPF check.

2. DKIM Header

The DKIM-Signature header contains the email’s DKIM signature, and the Authentication-Results header indicates the result of the DKIM verification.

3. DMARC Header

The Authentication-Results header indicates the result of the DMARC verification.

4. Authentication-Results Header

In addition to the SPF and DKIM specific headers, the Authentication-Results header provides an overview of the email authentication results.

Authentication-Results: mx.google.com;
 spf=pass (google.com: domain of sender@example.com designates 192.0.2.1 as permitted sender) smtp.mailfrom=sender@example.com;
 dkim=pass header.i=@example.com header.s=selector1 header.b=Gw+yUxcC;
 dmarc=pass (p=NONE) header.from=example.com

Exciting news in the email world!

Yahoo’s postmasters have just unveiled the new Sender Hub Dashboard!

This interface allows email senders to view and manage Yahoo sender services associated with their brand.

The dashboard offers various services, beginning with the Complaint Feedback Loop (CFL) service.

Say goodbye to the days of managing domains individually. Now, you can see all enrolled domains in one place and manage them in bulk using a CSV file. While there’s no word on a more convenient API method yet, let’s appreciate this significant advancement 🍾

You can also check the verification status of your domains.

Important: If you were a Yahoo FBL user, you have until August 1, 2024, to create an account on the Sender Hub and re-register.

If you want to see how you can add your domain, we wrote a mini howto on Sweego website

Email deliverability for developers: A technical guide

Pierre-Yves Dubreucq — Thu, 16 May 2024 16:26:09 +0000

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.
