Suped

Summary

A sudden drop in email open rates can be alarming for any sender. Often, it points to underlying deliverability issues rather than a direct problem with your content or audience engagement. These issues can range from a change in your sending reputation, getting listed on a blocklist (or blacklist), to changes in how internet service providers (ISPs) are filtering your mail. Addressing such a sharp decline requires a systematic investigation of your email infrastructure and sending practices to identify and rectify the root cause.

What email marketers say

Email marketers often face the challenge of sudden dips in open rates, which can be perplexing when no apparent changes have been made to their sending strategy. Their primary concerns revolve around diagnosing the problem quickly and implementing practical solutions. Many turn to community forums and peer advice to understand if others are experiencing similar issues, particularly with specific email service providers (ESPs). This shared experience highlights the community-driven approach marketers take to troubleshoot these often frustrating deliverability issues.

What the experts say

Email deliverability experts offer a more granular perspective on why open rates suddenly decline, focusing on the technical intricacies of mail flow and ISP filtering. They often distinguish between IP reputation and content-based filtering, highlighting that even if mail is accepted, it may not reach the primary inbox. Experts also provide critical insights into the role of email service providers and correct interpretations of authentication standards like DMARC, stressing that it's a reporting tool rather than a direct deliverability fix.

Expert view

Expert from Email Geeks explains that investigating a decrease in open rates should start by determining if the issue is localised to one ISP or affects all of them. If it's a single ISP, it indicates that particular provider may have begun filtering mail to bulk folders or specific tabs (e.g., Gmail's tabs).

Expert view

Expert from Email Geeks notes that at a certain sending volume, if an IP problem is identified, there is little the sender can do independently. The ESP is ultimately responsible for resolving such issues on shared IP pools.

What the documentation says

Official documentation and industry best practices consistently outline the foundational elements required for strong email deliverability, which directly influence open rates. These resources often focus on technical configurations like email authentication (SPF, DKIM, DMARC), maintaining a clean and engaged subscriber list, and adhering to sender guidelines set by major mailbox providers. When open rates suddenly drop, consulting this documentation helps identify misconfigurations or deviations from recommended practices that may have inadvertently occurred.
