Connecting e-mail channels

Gmail and Google Workspace, Microsoft 365, sending limits.

Gmail and Google Workspace

Under Integrations you connect a mailbox via OAuth. Credentials are stored encrypted and can be disconnected at any time.

Microsoft 365

Connect Microsoft 365 and Outlook through Microsoft Graph (OAuth with PKCE). Mail is sent on behalf of your account; uncertain sends are reconciled via Sent Items. Available once the operator has stored the app registration in Microsoft Entra ID.

Sending limits

Each mailbox has a daily limit and the sending window set in the campaign. Unconfirmed deliveries are reconciled before anything is sent again.
