Introduction

Verifying the correctness of a PayPal business email in an ASP.NET MVC is an essential step to ensure the smooth functioning of payment transactions. In this article, we will explore various methods to validate a PayPal business email ASP.NET MVC, along with code examples.

string pattern = @"^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$";

if (isValidEmail)
{
    // Email is 
}
else
{
    // Email is incorrect
}

In the above example, we assume that there is a method or API call to verify the email using the PayPal API. The isValidEmail variable is set based on the response from the API call. If the email is valid, further actions can be taken accordingly.

Conclusion
