Frequently Asked Questions
- What is an email validator?
An email validator checks an email address to determine whether it is properly formatted and whether it appears capable of receiving email.
- Is this email validator free?
Yes. You can validate up to 5 email addresses per day for free, with no account required.
- Does email validation send an email to the address?
No. The validator does not send a message to the recipient. It checks the address and its mail-delivery signals to determine whether it appears deliverable.
- What does "Valid" mean?
A Valid result means the email address appears deliverable based on the checks performed.
- What does "Invalid" mean?
An Invalid result means the address could not be confirmed as deliverable.
- What does "Unknown" mean?
Unknown means the system could not determine whether the address is deliverable with enough confidence.
- What is a catch-all domain?
A catch-all domain accepts mail for addresses that may not actually exist. Because of this, an individual address on a catch-all domain cannot always be confirmed with certainty.
- Can I validate an entire email list?
Yes. ClickDotEmail's full Email Validation service lets you validate larger lists instead of checking addresses individually.
