Common questions about Mail, with links to its docs and limits.
Connecting from code? See the Mail docs. How it works and what each plan includes: the Mail page.
Which mailboxes can connect?
Gmail and Google Workspace, Microsoft 365 and Outlook, Yahoo, and any mailbox that offers IMAP and SMTP with an app password. The connect page detects the provider from the address.
Do I need my own Google or Microsoft app?
For one-click sign-in with Google or Microsoft, yes: you register your app once and paste its client ID and secret, so your users see your name and you keep the relationship. Without one, people connect with an app password over IMAP.
I already use Nylas. How much changes?
The request and webhook formats are Nylas v3’s. Change the API host, the client ID and the secret; your code stays as it is.
How many mailboxes and sends do I get?
Free connects 3 mailboxes and sends 1,000 messages a month. Hobby connects 10, Business 250. Extra mailboxes are an add-on.
