Email verification for WooCommerce
Typos at checkout mean order confirmations that never arrive, and disposable addresses mean customers you can never reach. The MailSure plugin checks the address as the customer types and offers a one-click fix.
How it works
- 1
Install the plugin
Upload the plugin zip under Plugins, Add New in WordPress and activate it.
- 2
Paste your API key
Create a free MailSure account (100 free verifications every month) and paste a key in Settings, MailSure.
- 3
Choose what to block
Invalid addresses are always refused. Turn disposable, role and likely-typo blocking on or off, and choose which forms to protect.
Why use MailSure for this
Protects checkout and sign-up
Covers WooCommerce checkout and My Account registration, WordPress registration, comments, Contact Form 7, WPForms, Gravity Forms and Elementor Pro forms.
Never blocks a real sale
If MailSure is unreachable or you run out of credits, the address is accepted unchecked. A verification tool should not stop a customer paying.
Typo recovery
Visitors who type gmial.com get a friendly prompt with the corrected address instead of an error.

Frequently asked questions
- Does it slow checkout?
- A check normally takes a fraction of a second, results are cached for a day, and the plugin backs off if the service stops answering.
- What does it cost?
- Each address that gets a verdict uses one credit. Malformed addresses and unknown results are free, and a free allowance renews monthly.
- Can I allow my own domain?
- Yes, list domains under Always allow these domains and they are never checked or billed.
