How do API calls work for real‑time email verification?

Users can verify emails in real time using Webbula’s API as soon as an email address is entered into your form or system. The API helps verify email addresses and prevents typos during entry, ensuring only valid contacts are collected. It checks the email format for correct syntax, validates the domain by confirming DNS and MX records, and uses SMTP commands to test mailbox existence. The API also confirms if the email address exists and is capable of receiving messages, helping maintain list hygiene and improve deliverability. Our verification engine analyzes the address, detects threats or risks, and returns a clear status code — so you prevent harmful or invalid data from entering your database the moment it appears.
