AppRanks verdict
Generated from live marketplace data — refreshed daily
WPO365 | MICROSOFT 365 GRAPH MAILER is a category-leading WordPress app with a limited review volume. It is listed in the Email category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 39 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

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.

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.
