Half your replies
are robots
48% of replies across every provider are out-of-office bots. The real human reply rate sits near 0.6%. If you're celebrating 1%, assume half is machines.
Volume
stopped working
Sends tripled over 8 weeks. Replies didn't follow. The best week for replies was one of the lowest-volume weeks. The "send more" lever is worn out.
The lanes
that actually win
Google and Azure nearly doubled Outlook. One email plus three follow-ups captures almost every reply. Monday/Friday/Saturday beat midweek. Six data-backed moves inside.
