Steps to perform multi label word classification

I am trying to classify small strings into three categories.

Examples:

X(str column)                    y(str column)
[email protected]                   email_address
32                               age
@sadn                            invalid(since this is not a valid email address)
1234                             invalid(since this is not a valid age)

I am wondering which ML model needs to be used to achieve this case. And also what kind of text processing techniques need to be applied.
