Snov.io provides a comprehensive e-mail verification tool. To get quick and accurate verification, Snov.io uses several ways.
These methods include:
• Check for email syntax (search for characters in address name)
• Verify the domain name (check if there is a domain)
• Comparison between individual databases (Snov.io performs search for rejected emails in its database)
More sophisticated include:
• SMTP Authentication (sends an EHLO message to a mail server)
The balance between accuracy and speed is what makes Snov.io a competitive service between e-mail verifiers. In order to improve, they have implemented real-time verification to provide only the most accurate results in a short time. Snovio also provides Chrome extensions, so you can verify emails while surfing the web. Snov.io also has an API for full integration into any platform.
