Enter one email address in the checker above and click Validate. Proofy evaluates the address and returns a verification status without sending an email or requiring an account.
The result helps you decide whether the address is suitable to contact. Valid addresses pass the available checks. Invalid addresses are likely undeliverable. Risky and unknown results need more caution because the receiving server may not provide a definitive mailbox-level response.
The Free Email Checker is built for quick one-at-a-time checks. Use it when you want to test a single address before contacting someone, adding a lead, or correcting a suspected typo.
Proofy offers reliable email validation at an affordable rate, outperforming many pricier alternatives. It's straightforward to use and easy to integrate into existing systems.
Sending emails to invalid addresses can result in high bounce rates, which can harm sender reputation and email deliverability. Proofy.io verifies email addresses to ensure they are valid and deliverable, reducing bounce rates. It is easy to use, the user interface is friendly, and customer support was helpful.
Enter one email address in the checker, click Validate, and review the result. No account is required, and the checker does not send a message to the address.
Proofy checks the address format, domain and mail-server signals, then returns a verification status. The goal is to tell you whether the address appears deliverable, invalid, risky, or cannot be confirmed.
Proofy uses multiple verification signals rather than relying on a single check. Some mail servers do not provide a definitive mailbox response, so catch-all or otherwise uncertain addresses may be returned as risky or unknown instead of being overstated as valid.
Yes. The checker can evaluate addresses on major consumer and business email domains. Some providers limit mailbox-level confirmation, which can lead to a risky or unknown result rather than a definitive valid or invalid status.
Valid means the address passed the available checks. Invalid means it appears undeliverable. Risky means delivery is less certain or the address has a risk signal. Unknown means Proofy could not get enough information for a definitive result. Additional signals can identify cases such as disposable, catch-all, or role-based addresses.
Use Bulk Email Verification when you need to check a list of addresses. Use the Email Verification API when validation needs to run inside a form, application, CRM, or automated workflow.
The free checker performs verification in real time and does not send an email to the address being checked. Data handling and retention are governed by Proofy's Privacy Policy and Data Processing Agreement.
A disposable email is a temporary address created for short-term use. Proofy can identify known disposable email services and surface that signal in the verification result so you can treat the address with appropriate caution.
