WPO365 | MS GRAPH MAILER provides you with a modern, reliable and efficient way to send WordPress transactional emails from one of your Microsoft 365 / Exchange Online / Mail enabled accounts.

The plugin re-configures your WordPress website to send emails using the Microsoft Graph API instead of – for example – SMTP. Sending WordPress emails using the Microsoft Graph API has become the only available alternative after Microsoft has disabled basic authentication (username and password) over the SMTP protocol.

DELIVERY

  • Send WordPress transactional emails from one of your Microsoft 365 Exchange Online / Mail enabled accounts using Microsoft Graph instead of – for example – SMTP.
  • Choose between delegated (send mail as a user) and application-level (send mail as any user) type permissions.
  • Or: Select either a Microsoft 365 account or a personal Microsoft account, like Hotmail.com or Outlook.com, to send WordPress emails.
  • Or: Configure RBAC for Exchange Online and authorize as an application but with a limited scope e.g. one specific mailbox.
  • Daily refresh of Microsoft Graph access and refresh token.
  • Auto-flagging and suppression of duplicate emails.
  • Auto-retry when throttled (HTTP 429).

SEND AS HTML

  • Send emails formatted as HTML.

SAVE TO SENT ITEMS

  • Emails sent will be saved in the account’s mailbox in the Sent Items folder, further helping to track (successful) mail delivery.

ATTACHMENTS

  • Send files from your WordPress website as attachments.

  • Further improve overall security by choosing to store Azure Active Directory secrets in your WordPress WP-Config.php (on disk) and have those secrets removed from the database.

  • Send emails as BCC instead and prevent reply-to-all mail pollution.

REPLY-TO
