What the WordPress Integration Does
The Email Verifier by EcomTech WordPress plugin brings real-time email verification to every form on your WordPress site. Whether visitors are filling out contact forms, signing up for newsletters, registering accounts, or completing purchases, the plugin validates their email address before the form is submitted. Using our email verifier API behind the scenes, the plugin performs comprehensive checks including syntax validation, domain verification, MX record analysis, SMTP mailbox probing, disposable email detection, and risk scoring. Invalid and disposable emails are blocked with a user-friendly error message, while valid emails pass through without any friction or delay.
WordPress powers over 40% of all websites on the internet, and every WordPress site with forms faces the problem of invalid email submissions. Fake signups pollute your subscriber lists, inflate your email marketing costs, and skew your analytics. Spam bots submit forms with generated email addresses that bounce when you try to contact them. Visitors mistype their email addresses and never receive your confirmation messages. The Email Verifier by EcomTech WordPress plugin solves all of these problems at the point of entry. The plugin is lightweight, adding zero impact to page load times because it only runs when a form is submitted. It works with all major form plugins including Contact Form 7, Gravity Forms, WPForms, Ninja Forms, Elementor Forms, and Formidable Forms. Configuration is simple: install the plugin, enter your API key, select your verification strictness level, and every email field on your site is protected. Advanced users can customize which forms to verify, which email categories to block, and what error messages to display.
Step-by-Step Setup Guide
Install the WordPress Plugin
From your WordPress admin dashboard, go to Plugins, then Add New, and search for EV Email Verifier. Click Install Now and then Activate. Alternatively, download the plugin from our website, go to Plugins, then Add New, then Upload Plugin, and select the downloaded zip file. The plugin is lightweight at under 50KB and has no external dependencies beyond our verification API.
Enter Your API Key
Navigate to Settings, then EV Email Verifier in your WordPress admin sidebar. Enter your Email Verifier by EcomTech API key from your dashboard. Click Verify Connection to test that the API key is valid and your account is active. If you do not have an API key yet, click the Create Account link to sign up for free at our email verifier page and get your first 100 verifications free.
Configure Verification Rules
Set your verification strictness level. Strict mode blocks invalid, disposable, and risky emails. Standard mode blocks invalid and disposable emails but allows risky ones. Permissive mode only blocks clearly invalid emails. You can also enable or disable specific checks: disposable email blocking, role-based address blocking, catch-all domain warnings, and free email provider detection. Each check can be configured independently for different form types.
Select Form Plugins to Protect
The plugin auto-detects installed form plugins and lists them in the settings. Toggle verification on or off for each form plugin. You can also configure per-form rules if you want different verification behavior on different pages. For example, you might use strict verification on your registration form but permissive verification on your contact form to avoid blocking legitimate inquiries.
Customize Error Messages
Edit the error messages displayed when an email fails verification. The default message reads: Please enter a valid email address. You can customize messages for different failure types: invalid email, disposable email detected, and risky email address. Messages can include HTML for styling. Good error messages help users correct typos rather than abandoning the form, so keep them clear and helpful.
Test and Monitor
Submit a test form with a valid email, an invalid email, and a disposable email to verify the plugin is working correctly. The plugin settings page includes a verification log showing recent checks with their results. Monitor the log to ensure the plugin is catching invalid emails without blocking legitimate ones. The log also shows your credit usage and remaining balance so you can plan your verification budget.
