The Gmail provider sends email through the Gmail API using OAuth 2.0. This means NimblyMail never stores your Google password — it holds only a temporary access token that Google can revoke at any time from your Google account settings. This option works for both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. […]

NimblyMail uses a centralized OAuth proxy (oauth.nimblymail.com) so you do not need to register your own Azure application. One click and you’re connected. When to use Outlook / Microsoft 365 […]
