Disclosing the entire email verification process would make it easy for DEA companies to game the system, so we’ll cover only the basics here.
While validating email addresses, QuickEmailVerification classifies the domain names, like free email, organizational email, ISP-based address and so on. One of these categories is that of disposable email provider domains.
That means we maintain a list of domains that offer DEAs. However, new services keep coming up on a regular basis. Hence, we also track new services and add their domains to update our database.
Finally, our algorithms study patterns of temporary addresses to make our fake email detection more accurate.
