DeBounce.io Email Validator

Description

  • Contact Form 7
  • Gravity Forms
  • WordPress comments
  • WordPress registration forms
  • WooCommerce
  • Ninja Forms
  • Jetpack/Grunion
  • and with any other form which uses the is_email() function (no changes required).

The plugin can also be integrated into 3rd party forms that do not use the is_email() function.

What this plugin do?

Based of DeBounce API documentation, this engine perform the following checks:

  • DNS validation, including MX record lookup
  • Disposable email address detection
  • Misspelled domain detection to prevent Typosquatting
  • Syntax verification (IETF/RFC standard conformance)
  • Temporary unavailability detection
  • Mailbox existence checking
  • Catch-All testing
  • Greylisting detection
  • SMTP connection and availability checking

The plugin requires an API Key to perform. You can get a free API by clicking Register on DeBounce.

DeBounce don’t send any email to the recipient address during the entire validation process. All processing is done on it’s servers, your IP addresses and domains are not affected in any way by the DeBounce service. So, your IP or domains never get blacklisted, since this plugin never use them.

DeBounce really cares about data protection and user privacy and never store any emails called from API. For more information, please read the following links:

Fast for Public email but slow for other domains, example for: LIVE, GMAIL, HOTMAIL, YAHOO MAIL etc. takes about 4 seconds, but when comes to any other domains, the validation can take up to 10-20 seconds to validate. Thats my experience anywayzz. Works, but bit slow You get 100 free checks, BUT the paid plan is super cheap, minimum $10USD for 5000 checks and credits never expire. There's other plans

Tested the plugin from a handful of choices and this one performed far worse than the others - not sure if it even checks email addresses at all?

So far working as expected with Gravity Forms. Will be testing with WooCommerce too and the cost is very reasonable for the service.

I use debounce on 3 sites and it works perfect. I just make sure to check 1 time/mo to see my credits left and forget about it for whole month. It works perfectly.

Really useful plugin in preventing the users to submit the forms using invalid emails. I am happy with it 🙂

I have been using this plugin for the last 10 months. It saved us from 8,260 invalid and disposable email addresses. Nice job from DeBounce.
