EasyDMARC Email Verification

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.

How it works

1. A visitor submits a form containing an email field.
2. The plugin sends the address to the EasyDMARC API for real-time verification.
3. 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.
4. 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) when WP_DEBUG_LOG is 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.
