What Is the Disable Theme Auto-Update Emails feature?
WordPress’s background update system can auto-update installed themes (when enabled). When themes auto-update, WordPress sends a notification email to the site admin listing the updated themes.
The Disable Theme Auto-Update Emails feature suppresses this email. The auto-updates still happen; only the notification is removed.
Why You Need It
For sites with multiple themes installed (common for staging environments, multi-brand deployments, or theme testing workflows), the email can be a constant stream:
- A site with 5 themes and auto-updates enabled might receive 5-10 theme update emails per month
- Most sites only actively use one theme; the other themes are dormant
- The email doesn’t require action; the updates are already done
The trade-off: if a theme auto-update introduces a bug or breaks the design, the email is the admin’s signal to test the site. Disabling the email removes that signal. For high-stakes sites, leave it enabled.

Configuration Options
| Option | Description | Default |
|---|---|---|
| Disable Auto Update Notification Emails for Themes | Master toggle. | Off |
No nested options.
What Gets Suppressed
| Sent when feature off | Sent when feature on | |
|---|---|---|
| “Some themes have been updated” (after auto-update) | Yes | No |
| Manual theme update email (from clicking “Update”) | Yes | Yes (separate flow) |
| Theme activation/switch emails | Yes | Yes (separate flow) |
The feature only suppresses the auto-update-specific email. Manual updates and theme switching notifications are unaffected.
What Does NOT Get Affected
- Theme auto-update itself: Still happens (controlled by each theme’s “auto-update” setting)
- WordPress core auto-update emails: Separate feature (Disable Core Auto-Update Emails)
- Plugin auto-update emails: Separate feature (Disable Plugin Auto-Update Emails)
- Manual theme update emails: Sent when an admin clicks “Update” on a theme
- Theme switch emails: Different email flow (when an admin switches the active theme)
Advanced Options (Developers)
This feature registers 2 WordPress hooks in disable-update-emails.php:
Filters:
auto_theme_update_send_emailcallsdisable_theme_update_emails()(Disables theme auto-update notification emails)auto_theme_update_send_emailcallsapply_filters()(Customizable filter)
// Hooked in disable-update-emails.php
add_filter( 'auto_theme_update_send_email', 'disable_theme_update_emails' );The feature modifies WordPress behavior by registering or removing hooks. Disabling it reverses those changes.
Troubleshooting
The theme auto-update email is still being sent
Cause: The toggle is off, or another plugin is sending its own theme update notification.
Fix: Verify the toggle is on. Check for security or monitoring plugins that may send their own update notifications.
I disabled theme auto-updates for all my themes but still get the email
Cause: The email is only suppressed if there were updates. If no themes auto-updated, no email is sent. If at least one did, the email is sent (regardless of how many were excluded).
Fix: Verify which themes are set to auto-update (Appearance > Themes > Theme Details > auto-update toggle). If at least one theme is set to auto-update, the email will be sent when that theme updates.
I want a daily summary of theme updates instead of per-update emails
Cause: WordPress sends one email per auto-update run.
Fix: Disable all auto-update emails (Core, Plugins, Themes), then add a custom cron job that runs daily and emails a summary of all theme updates from the last 24 hours. Use the auto_theme_update_email filter to log updates to a transient, and a custom cron to read and email the summary.
I disabled theme auto-updates via wp-config.php (DISALLOW_FILE_MODS)
Cause: The DISALLOW_FILE_MODS constant blocks theme auto-updates entirely; the email is irrelevant.
Fix: The email will not be sent because updates are not happening. The toggle is irrelevant in this case. The toggle is for sites that allow updates but want to suppress the email.
I want the email for security-related theme updates only
Cause: WordPress does not distinguish security vs feature theme updates in the email.
Fix: This is not currently possible with WordPress’s email system. You’d need a custom plugin that tracks which themes have security flags and sends emails only for those.
