Surgence of bot clicks in consumer emails drives push for verified metrics
A report from Omnivery shows bot-click rates in B2C emails surged from 2% to 16% over three years, fueled by automated pre-fetching and archiving.
The short version
- Automated bot clicks in consumer email inboxes and newsletters rose from 2% in 2023 to 16% in 2026, driven largely by security pre-fetching from major mailbox providers.
- The spike has led the newsletter platform Beehiiv to introduce "verified clicks" to filter out bot activity and prevent advertising fraud.
- Industry experts report that advertisers are increasingly demanding proof that bot clicks are filtered out of engagement metrics.
