July 2022 Summaries

You're sending emails from multiple sources, and while your DKIM and SPF are set up correctly, your DMARC report shows that SPF didn't pass due to forwarding, causing alignment issues. Forwarding can break DKIM authentication as it alters message content and headers, but sender information usually withstands forwarding. However, when forwarding occurs, the Return-Path header domain may not match the From domain, leading to SPF failure. To mitigate this, you can have both DKIM and SPF set up and take steps to prevent forwarding, such as using a 'reject' DMARC policy or leveraging mailbox providers' ability to identify forwarded emails through Authenticated Received Chain (ARC) standards, which allow authentication results to be added to message headers when an email is forwarded.

We are most email providers have deliverability issues due to their approach of treating all customers equally, without taking care of shared IPs, using separate IPs for transactional and marketing emails, or proactively helping customers. In contrast, Postmark takes a different approach by not allowing bad senders into its platform, having multiple high-reputation IP pools, manually approving every account, monitoring spam complaint rates and bounce rates closely, sharing detected delivery issues with customers, and building an infrastructure to separate transactional and broadcast emails, resulting in 99% global delivery rates for both types of email.

The Postmark App for Stripe is a new integration that allows users to send emails to their customers without leaving the Stripe platform. This app brings email sending functionality into Stripe, making it easy to build relationships with customers, reduce churn, and grow business through targeted communication. Users can choose between HTML and plain text templates, track customer engagement, and view activity stats within Stripe. The Postmark App is now available in the Stripe App Marketplace for easy installation.
