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). ## ພາບໜ້າຈໍ [⌊A fake address is caught right in the form: Contact Form 7 submission stopped, the visitor sees exactly which field to fix.⌉⌊A fake address is caught right in the form: Contact Form 7 submission stopped, the visitor sees exactly which field to fix.⌉[ A fake address is caught right in the form: Contact Form 7 submission stopped, the visitor sees exactly which field to fix.

Go to **Settings -> Mail7 Validation** to choose where validation runs and, optionally, add your API key. ## ຄຳຖາມທີ່ພົບເລື້ອຍ ### 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. ## ການຣີວິວ ບໍ່ມີການຣີວິວສຳລັບປລັກອິນນີ້. ## ຜູ້ຮ່ວມພັດທະນາ ແລະ ຜູ້ພັດທະນາ “Mail7 Email Validation” ແມ່ນຊອຟແວໂອເພັນຊອດ (Open Source). ບຸກຄົນຕໍ່ໄປນີ້ໄດ້ມີສ່ວນຮ່ວມ ໃນການພັດທະນາປລັກອິນນີ້. ຜູ້ຮ່ວມພັດທະນາ * [ denm ](https://profiles.wordpress.org/denm/) [ແປ “Mail7 Email Validation” ເປັນພາສາຂອງເຈົ້າ.](https://translate.wordpress.org/projects/wp-plugins/mail7-email-validation) ### ສົນໃຈຮ່ວມພັດທະນາບໍ່?
