Email verification to prevent fraud (2025 guide)
Blog post from Didit
In 2025, email remains the primary vector for fraud, and the rise of hyper-disposable domains is challenging traditional security measures, making email verification crucial for businesses reliant on onboarding and trust. The FBI reported significant cybercrime losses in 2024, with email being central to many incidents, highlighting the need for modern, efficient email verification systems like Didit, which offers quick integration through Workflows or API. Email verification, which involves sending a one-time passcode (OTP) to confirm inbox control, plays a vital role in preventing fraud by reducing multi-accounting and account takeover risks, while also improving email marketing strategies by enhancing deliverability and reducing bounces. The evolving landscape of email-driven fraud vectors includes phishing, business email compromise, and personal data breaches, emphasizing the importance of combining OTP verification with validation and reputation checks to mitigate risks. Didit’s approach not only aids in confirming email ownership but also supports risk-based authentication, helping to maintain compliance and reduce operational risks by ensuring that only legitimate emails are used for account sign-ups and sensitive transactions.
