Add a Google or Microsoft 365 sender

You want an email to come from a named person, with their signature and replies going straight to them. A Google Workspace or Microsoft 365 sender is that person’s mailbox, connected by signing in and granting Pyn permission to send. The person signs in themselves; an admin cannot connect someone else’s mailbox.

  • You are signed in to Pyn as the person whose mailbox you are connecting. To connect someone who has no Pyn login, create an auth link instead.
  • Your organisation allows the Pyn app. In Google Workspace that may need an admin to approve the app; in Microsoft 365 the account needs an Exchange Online mailbox.
  • Add Microsoft 365 Email Sender appears only in workspaces where Microsoft 365 is enabled.
The Add menu on the Senders view, open, listing Add Google Email Sender, Add Slack Sender, Add Email Sender and the auth link options.
The Add menu on Senders is where every new sender starts.
  1. In Pyn, open Settings in the left navigation, then Senders under General.

  2. Select Add, then Add Google Email Sender.

  3. Google opens. Choose the account and select Allow. Pyn asks for your email and profile and for gmail.send, which lets it send email as you; it cannot read your mail.

  4. Google returns you to Pyn. Your sender is listed with your name and address.

  5. Open the sender’s … menu and select Send Test. “Test Message Sent” confirms it; check your inbox.

The new row shows Active, and the sender’s panel lists the Sender Name, Email and the Google Hosted Domain or Microsoft Tenant. If the row later shows Requires reauth, the mailbox’s password changed or access was revoked; the owner of that mailbox opens the sender and selects Reconnect. If someone else tries, Pyn asks them to confirm they have permission for that address first.
