It helps site administrators create flexible forms and send messages through WordPress mail, custom SMTP, Microsoft 365 SMTP OAuth, or a test/log-only mode for staging sites. Process2IT Forms Mailer is developed by Process2IT. The plugin uses its own form tag system: ``` {{field type="text" name="your-name" required="true" label="Your name"}} ``` Forms can be published with: ``` [process2it_form id="123"] ``` or with the server-rendered Process2IT Form block. Submission storage is optional and disabled by default. Mail logging is optional and masks secrets. Version 1 supports Microsoft 365 SMTP OAuth configuration for `smtp.office365.com` with STARTTLS and XOAUTH2. Microsoft Graph API mail delivery is architecturally prepared but not included in the first release line. ### Privacy Process2IT Forms Mailer does not track users and does not store submissions by default. If submission storage is enabled, stored data may include submitted field values and, depending on settings, IP address, user agent, referrer and uploaded files. Administrators can configure retention and delete submissions. ### External services Process2IT Forms Mailer can connect to external SMTP services only when configured by the administrator. For Microsoft 365 SMTP OAuth, the plugin connects to: * `https://login.microsoftonline.com/` for OAuth authorization and token refresh. * `smtp.office365.com` for SMTP delivery using STARTTLS and XOAUTH2. Data sent to these services may include the tenant ID, client ID, client secret, authorization code, refresh token during token refresh, redirect URI, requested OAuth scopes, authorized sender mailbox, email recipients, subject, message body and optional attachments. These services are provided by Microsoft.

No. Submission storage is disabled by default and must be enabled per form. ### Does the plugin send data to external services automatically? No. External mail services are contacted only when the administrator configures a mailer that requires them. ### Does Microsoft 365 SMTP OAuth use Basic Authentication? No. Version 1 uses OAuth 2.0 with XOAUTH2 for Microsoft 365 SMTP. ### Which Microsoft 365 scope is required? The OAuth app needs `offline_access` and `https://outlook.office.com/SMTP.Send`. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Process2IT Forms Mailer” is open source software.
