In digital communication, marketers face a major challenge: the quality of their databases. Every year, millions of email addresses become inactive, turn into spam traps, or are simply typos. This leads to a poor reputation with providers like Gmail or Outlook, which in turn causes even legitimate emails to end up in the spam folder. Mailcheck addresses this issue directly and offers an automated solution to eliminate these 'dead' contacts. The solution: How Mailcheck works. Validation via social networks. Unlike traditional tools, Mailcheck uses an algorithm that compares email addresses with profiles on social networks. This ensures that there is actually an active user behind each address. Real-time verification. Thanks to API integration, emails can be checked the moment they are entered (e.g., in a contact form). This prevents incorrect data from entering the system in the first place.

Compared to competitors like ZeroBounce or Hunter, Mailcheck offers unique added value through its social network component, justifying the slightly higher price per validation.
