How does email validation work?
Try our free demo to see for yourself. We do a full check to ensure the actual mailbox is valid and able to accept emails. Integrate this into your own app or signup forms using our API, or simply upload a list in our easy-to-use dashboard.
There are essentially 3 steps to do this properly. Many services and scripts out there only do one or two stages. You gotta do all 3 otherwise it ain’t worth doing!
1. Syntax/format checking
This is to ensure that the email meets certain basic criteria such as whether it contains an ‘@’ sign etc.
2. Domain checking
Does the email address have a valid domain name? Is the domain name configured to accept email at all?
3. Mailbox checking
Is the part before the ‘@’ sign a valid mailbox? This is the really clever part, and what sets our service apart from many others.
