Why has my email click-through rate dropped in Gmail?

Summary

A drop in email click-through rates (CTR) in Gmail can be attributed to a complex interplay of factors encompassing list hygiene, authentication, content, design, reputation, and technical elements. Poor list quality and hygiene, combined with unengaging subject lines and ineffective email design (especially on mobile), can deter clicks. Gmail's placement of emails in the Promotions tab rather than the Primary tab further reduces visibility. Technical issues, such as rendering problems, broken links, and Microsoft SafeLinks redirections, degrade user experience. High spam complaint rates and authentication failures negatively impact sender reputation and deliverability, potentially leading to email rejection or throttling. Ensuring proper SPF, DKIM, and DMARC configuration is critical. Reviewing Google Postmaster Tools can give insight to authentication issues and domain reputation. Regularly cleaning your list, optimizing content and design, and actively monitoring reputation are crucial for maintaining and improving CTR.

Key findings

  • List Quality & Hygiene: Poor list quality and lack of hygiene (inactive subscribers) directly reduce engagement and CTR.
  • Subject Line Engagement: Unengaging subject lines lead to lower open rates and subsequent reduction in CTR.
  • Mobile-First Design: Poorly designed emails, particularly on mobile devices, deter clicks and reduce engagement.
  • Promotions Tab Placement: Consistent placement in the Promotions tab significantly reduces email visibility and CTR.
