WHEN IS THE BEST TIME TO SEND EMAILS IN PR? (A STUDY OF 4.5M EMAILS)

Summary from the TLDR Marketing newsletter

8 to 9 AM local time is the most effective window for PR emails because 36% of opens occur during that hour. Monday delivers the strongest performance for both opens and replies across staff journalists and freelancers. Freelancers show steadier engagement during the week but still peak around 8 AM and drop on Friday. US journalists engage most between 9 and 11 AM, and UK journalists peak between 7 and 9 AM, but individual timing still depends on publication and personalization.
