## Сүрөттөө

Mail7 Email Validation checks email addresses in real time as they are entered, 
using the [Mail7](https://mail7.net/) API. It stops fake and undeliverable addresses
from getting into your user base, comments and form submissions – which means fewer
bounces, less spam and cleaner lists.

**Three verdicts, not two.** Real mail servers do not always give a straight answer:
catch-all domains, greylisting and disposable providers make some addresses genuinely
unverifiable. Mail7 returns **Valid**, **Not Valid**, or **Unknown**, and this plugin**
does not block Unknown addresses by default**, so you never turn away a real person
over an address that simply could not be confirmed.

#### What it checks

 * Syntax / format
 * Domain MX records (can the domain receive mail at all)
 * Live SMTP mailbox check
 * Disposable / temporary address detection

#### Where it plugs in

 * WordPress user registration
 * Comment author emails
 * Contact Form 7 email fields
 * WPForms email fields

#### Reliable by default

 * Results are cached, so the same address is never re-checked (fast, and no wasted
   API calls).
 * If the Mail7 API is briefly unreachable, the plugin fails open – your forms keep
   working, no one is ever locked out by an outage.

#### API key

Works out of the box on Mail7’s free anonymous tier (rate-limited). For higher volume,
paste a Mail7 API key in the settings – get one at [mail7.net](https://mail7.net/).

### External services

This plugin sends each submitted email address to the Mail7 API (https://mail7.net/
api/validate-single) to determine whether it is deliverable. Only the email address
being validated is sent. See the Mail7 [Privacy Policy](https://mail7.net/privacy-policy.html)
and [Terms of Service](https://mail7.net/terms-of-service.html).

## Орнотуу

 1. Upload the plugin to `/wp-content/plugins/`, or install it from the Plugins screen.
 2. Activate it.
 3. Go to **Settings -> Mail7 Validation** to choose where validation runs and, optionally,
    add your API key.

## FAQ.KG

### Do I need a paid account?

No. It works on the free anonymous tier. A Mail7 API key raises the rate limit and
volume.

### Will it block real users?

Not for unverifiable addresses. By default only addresses Mail7 reports as **Not
Valid** (do not exist / no mail server) are blocked. “Unknown” addresses are allowed.
You can optionally block Unknown too, but it is off by default on purpose.

### What happens if Mail7 is down?

The plugin fails open: submissions are allowed. Validation never becomes a single
point of failure for your forms.
