WordPress plugin
Validate email addresses in your WordPress forms without writing a single line of code. Download it in your dashboard under Integrations, paste your API key, done.
- Works with Contact Form 7, WPForms, Gravity Forms, Elementor Pro Forms and Ninja Forms.
- Rejects invalid, undeliverable and disposable addresses with an error right at the email field.
- Optional rules for SMTP mailbox checks, role addresses, high-risk domains and typo suggestions ("Did you mean …?").
- Forms never break: if Hermes cannot be reached or your limit is reached, submissions are accepted as usual.
- Results are cached, so the same address only uses one validation per week.
- Error messages can be customized and ship in English and German.
- New Integrations page in the dashboard with the download and a four-step setup guide.
