Inboxes
Why do 50/50 plans have more Microsoft inboxes than Google?
Updated Nov 6, 2026
ScaledMail's 50/50 refers to sending volume, not inbox count.
Microsoft inboxes send fewer emails per inbox, so more inboxes are needed to match the volume. Google inboxes can send more per inbox, so fewer are needed.
The result is equal cold sending volume from both providers, but different inbox counts.
