Every mailbox your users have, behind one API
12 providers across email, calendar and contacts. Each page says what that provider can do, how an account is linked, and the limits a buyer needs to know before they commit.

What each one can do
Capability matrixThe matrix, without the asterisks
A capability is listed only where it actually works. Where a provider cannot do something, the cell is empty rather than footnoted — and where it needs a paid seat on the connected account, the provider's own page says so.
Scroll the table sideways to see every provider.
