Mad Cow Owner Update Notifications for MainWP adds an “Email owner” button to every row in your MainWP Manage Sites table. After running updates or maintenance, click one button and the site’s owner receives a templated email letting them know their site is up to date. Need to notify a dozen owners at once? Check the rows and hit Send to Selected Owners — a sticky toolbar shows live progress and a summary at the end.

This is not a reporting tool. There is no report builder, no scheduling, and no PDF. It adds a send button to the row you are already looking at, so notifying an owner after updates costs one click instead of a context switch into your mail client.

Key features

One-click send — an “Email owner” button appears in every row of MainWP’s Manage Sites table.
Batch send — check multiple rows and send to all owners at once, with per-row progress and a summary at the end.
Persistent “recently sent” state — green button shows how long ago each owner was last notified.
Per-site owner name + email — stored server-side; edit them all from one settings screen.
Customizable template — subject, body, and from-address. Placeholders: {first_name}, {site_name}, {site_url}.
HTML body support — basic HTML allowed for images, links, and formatting.
No page reloads — everything is AJAX; scroll position, filters, and table state are preserved.
Sticky batch toolbar — stays visible under the MainWP header while you scroll long site lists.
Developer-friendly — clean hooks and filters for extension. Nothing “phones home.”
