About Temp Mail Detector
From the official readme · v1.3.0Description
The Temp Mail Detector WordPress Plugin is a privacy-first temporary email prevention plugin which helps stop disposable emails from being able to sign up or comment on your website. With built-in WooCommerce support, you can also protect your store from fraudulent orders and registrations using disposable email addresses.
By combining the ability to use your own custom blocklist alongside the optional Temp Mail Detector database, you can choose which email providers are allowed or not allowed to use your website.
What’s available
This plugin offers multiple options:
* Blocklist – You can enter your own list of domains to block.
* Protect comments – Choose if you would like the plugin to mark comments as spam.
* Protect WooCommerce – Block temporary emails during WooCommerce checkout, customer registration, and account updates.
* Plus emails – Block emails which have a + in the user part.
* Multiple dots – Block emails with multiple dots in the user part (e.g., first.middle.last@example.com).
* External check – This makes use of the live Temp Mail Detector database for real-time checks.
To check against the Temp Mail Detector database, you will need to register for a free API key.
Each API key gets 200 lookups each month, which reset on the first of the month.
Where Temp Mail Detector Protects Your Site
Temp Mail Detector automatically blocks disposable email addresses in these common situations:
WordPress Protection:
* Someone creates a new user account → Signup is rejected
* Someone leaves a comment → Comments are automatically marked as spam
* A user updates their account email → Changes are blocked
WooCommerce Protection:
* A new customer registers → Account creation is blocked
* A customer makes a purchase → Order is blocked
* A customer updates their account email → Email changes are prevented
* Customers use the checkout form → Checkout is blocked
External services
If external checks are enabled via the use of an API key, when checking if an email is temporary or not through the Temp Mail Detector API, only the website address of the email is sent to be analysed. Your users’ email addresses are never transmitted or shared with anyone.
If an email is user@website.com, this plugin will only send website.com to be analysed. By never sharing your users’ emails, you can both check if an email is disposable while also maintaining your users’ privacy.

Frequently asked questions
Do I need an API key to use this plugin?
No, not at all. The plugin works out of the box with local blocklist validation. The API key is optional if you want to use the Temp Mail Detector database for real-time checks. You can register for a free key at tempmaildetector.com.
How many email lookups do I get with the free API key?
Each free API key includes 200 lookups per month, which reset on the first of the month. Paid plans are available for higher volume needs.
Will this plugin slow down my site?

Does it work with WooCommerce?
Yes! The plugin includes full WooCommerce support. It blocks temporary emails during customer registration, checkout, and account updates.
What about user privacy?
Your users’ email addresses are never shared. When checking against the live database, only the domain is sent, not the full address.

Will blocked emails receive a notification?
