EMAIL MARKETING TRENDS: WHAT WE LEARNED FROM 79,235 REAL EMAILS

Summary from the TLDR Marketing newsletter

Weekend sends now match weekdays, shrinking the old gap and making Monday the least crowded inbox. Subject lines are getting shorter and less shouty, favoring clear specifics over urgency. Per-brand volume is flat, but more brands are sending consistently, with weekly cadence on the rise. Emails remain heavy on images and links. Industry differences are wide, so broad benchmarks mislead. Attention is shifting toward newsletters and re-engagement, not one-off promos.
