EMAIL DRIFT
0domains switched email provider
Across the tracked catalog · most recent complete day (Sep 16)

Where the mail goes. An MX move changes which company receives every message sent to the domain, and migrations show up here first.

No net movement between named providers in the watched flow map, which is a narrower read than the count above it.
Watched domains None of them are on a watch list yet. Name a domain and every time it moves its mail you hear about it in minutes. Watch a domain

No net movement between named providers on watched domains in the last 24 hours.
