Description
EasyDMARC Email Verification connects your WordPress forms to the EasyDMARC email verification API and validates every submitted email address before the form is accepted. It helps you block invalid, disposable, risky, and undeliverable addresses from entering your system.
All verification requests are performed server-side — no JavaScript is sent to the browser. Credentials are encrypted with AES-256 using your site’s AUTH_KEY.
Supported form plugins
- Elementor Pro Forms
- Contact Form 7
- WPForms
- Ninja Forms
- Fluent Forms (free and Pro)
- Gravity Forms
- SureForms
How it works
- A visitor submits a form containing an email field.
- The plugin sends the address to the EasyDMARC API for real-time verification.
- If the result is not in your allowed list (e.g. you block “undeliverable”), the form is rejected and a clear error message is shown under the email field.
- Deliverable addresses pass through normally.
Key features
- Per-status control — independently allow or block deliverable, risky, undeliverable, and unknown results.
- Allow on API error — optionally permit submissions when the verification service is unavailable.
- Custom error messages — set your own text for invalid, risky, and API-error scenarios.
- Test Email tab — verify any address from the admin panel and inspect the raw API result.
- Bulk CSV verification — upload a CSV file with up to 500,000 email addresses, verify them in bulk, view a visual breakdown (donut chart), and export filtered results as CSV.
- Buy Credits tab — browse available EasyDMARC plans, see your current balance, and subscribe directly from the WordPress admin.
- Credit usage dashboard — see your allocated credits, current balance, and usage at a glance.
- Debug logging — errors are written to
debug.log(with email addresses redacted) whenWP_DEBUG_LOGis enabled.
Privacy
Email addresses are sent to https://sender-api.easydmarc.com for verification. See EasyDMARC’s legal and privacy information at https://easydmarc.com/legal for details on how verification data is handled.
Requirements
- WordPress 5.8 or later
- PHP 7.4 or later
- OpenSSL PHP extension
- An EasyDMARC account with an API Client ID and Client Secret
- One or more supported form plugins (Elementor Pro, Contact Form 7, WPForms, Ninja Forms, Fluent Forms, Gravity Forms, or SureForms)
Installation
- Upload the
easydmarc-email-verificationfolder to/wp-content/plugins/and activate it, or search for “EasyDMARC Email Verification” in Plugins Add New and click Install. - Go to EasyDMARC Settings and open the API Settings tab.
- Enter your EasyDMARC Client ID and Client Secret.
- Click Verify API Key to confirm your credentials are working.
- Enable the form integrations you use and configure which verification statuses are allowed.
FAQ
-
Where do I get the API credentials?
-
Log in to your EasyDMARC account at https://easydmarc.com/ and navigate to the EasySender section to generate your Client ID and Client Secret.
-
Does this work without a paid EasyDMARC plan?
-
A free account includes a limited number of verification credits. Paid plans are required for higher volumes. See https://easydmarc.com/pricing/ for details.
-
Will the plugin block my forms if the API is down?
-
No — if you enable Allow submission if verification service is unavailable in the settings, form submissions will pass through normally when the API cannot be reached.
-
Which email statuses should I allow?
-
At minimum, enable deliverable. Enabling risky is optional — risky addresses exist but may bounce. We recommend blocking undeliverable and unknown to keep your list clean.
-
Are email addresses stored or logged?
-
No email addresses are stored by this plugin. Debug log entries automatically redact all email addresses before writing to the log file.
-
Is the plugin compatible with caching plugins?
-
Yes. All verification requests are made server-side during form submission (a POST request), which bypasses page caching.
-
Where can I report a bug or request a feature?
-
Please open a thread in the plugin’s support forum on WordPress.org.

Changelog
1.1.4
- Fixed: Credentials saved via the “Verify API Key” button are now encrypted before storage (security fix).
- Fixed: All remaining “Unauthorized.” AJAX error messages are now translatable.
- Fixed: Error message in usage tab now inserted as text to prevent potential XSS.

1.1.3
- Fixed: Text domain updated to easydmarc-email-verification across all PHP files to match the plugin slug.
