Description
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.
* 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

WordPress Protection:

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.
