in real time.
- Syntax control
The syntax check is made to be sure that the provided address respects the standard for the e-mail addresses. In particular it verifies if the specified address has a domain starting with the @ symbol and a first part specifying the recipient.
- Domain control
The domain of the specified e-mail address is actively checked via a DNS request to verify if it exists or not. This validation is done in realtime; in this way you always have the latest available data.
- Ultrafast validation
Every invocation of this API has a very low response time: we measured it and the system could need from 100 to 600 milliseconds to provide the response. Only some rare cases needed 1 complete second to handle the request.
- Secure communications
Security is a priority on SFour. All the data to and from our systems are encrypted with 256-bit SSL algorithms (HTTPS).
