原文外掛簡介
BounceLens Email Check stops bad email addresses before they reach your user list, your shop or your inbox.
When a visitor types an address, the plugin checks it and shows a clear message if something is wrong:
Typos: [email protected] gets “Did you mean [email protected]?”
Dead domains: domains that do not exist, have no mail server, or say they accept no email.
Throwaway addresses: Mailinator, 10minutemail and thousands of similar services.
Optional: shared inboxes (info@, sales@) and free providers (for sites that want work addresses).
It runs on your own server. There is no account, no API key, no credits and no limit, and no address is sent to BounceLens or anyone else.
Forms it checks
WordPress registration, and the sign-up form on multisite
Edit profile, when someone changes their own address
Comments from visitors who are not logged in
WooCommerce account registration, account details, and the billing email at checkout (shortcode checkout and the checkout block)
Contact Form 7
WPForms
Ninja Forms
Forminator
Formidable Forms
Fluent Forms
Mailchimp for WordPress (MC4WP) sign-up forms
Gravity Forms
Elementor Pro forms
Each group can be switched off under Settings → BounceLens Email Check.
Honest about what it can do
The plugin checks the format, the domain and its mail server, and known throwaway services. It cannot tell whether one specific mailbox exists: that needs a conversation with the receiving mail server, which this plugin does not do.
If your server’s DNS does not answer, the address is accepted. A slow resolver never locks real people out of a form.
For developers
bouncelens_email_check_problem( $email ) returns the message for an address, or null when it is accepted. Use it in your own form handler.
Filter bouncelens_email_check_result changes the result for one address.
Filter bouncelens_email_check_resolver replaces the DNS resolver.
