## 説明

This plugin will verify every email address submitted by users.
 It’ll automatically
detect and block disposable, temporary email addresses. It’ll give a nice warning
message when users are signing up, logging in, or changing email to a temporary 
email.

The plugin checks the domain name using a service named
 [IsTempMail](https://www.istempmail.com/?ref=wp).
If a domain name is blocked, it will be stored into a local blacklist. You can also
manage your own local whitelist and blacklist to allow or disallow certain domains.

The plugin integrates with the WordPress built-in function `is_email()`.
 It works
seamlessly with other plugins including WooCommerce, Contact Form 7, Gravity Form,
Jetpack/Grunion contact forms, Kadence Blocks Forms as well as other formbuilders
and ecommerce plugins and WordPress’ own registration form.

## インストール

Sign up and get your API token at [IsTempMail](https://www.istempmail.com/sign-up?ref=wp).

Upload the plugin to your blog, then click Activate it under Plugins > Installed
Plugins.
 Then enter the API token at your WordPress Dashboard > Settings > IsTempMail.

## FAQ

### Do you send my user email addresses to other servers?

No, we don’t. The plugin will only send the domain part of email address to validate.

### Is the plugin free?

Yes, the plugin is free to use. IsTempMail also offers a free plan that will be 
sufficient
 for most blogs. You will be notified when you use more credits than 
included in the free plan.

### What happens if the service is down?

A downtime is very unlikely, the IsTempMail service has outstanding availability
of 99.99%
 over the last 6 months. But the plugin was developed to be stable in 
the unlikely event of a temporary downtime. It will continue to work, validating
emails using your local blacklist and whitelist. Your users will be able to sign
up, log in and comment on your blog just fine.

### What happens to existing users with fake email address

Existing users registered with fake email addresses won’t be able to log in to your
blog when
 the plugin is activated. Be prepared for users contacting you regarding
this topic. Usually people who used a disposable email address won’t come back to
your website though.

This plugin is outstanding, it does exactly what I expected. I also had a problem
and the support was very fast and efficient. Highly recommended.

offers of disposal emails grow faster than the plugin can keep up with. From the
first three disposables offered by google, one was blocked. A BIG FAIL
