Use linq
Sorry this is in VB, you can do it in C#.

SQL

Dim goodemails() As String = (From email As String In readText Where validEmail(email) Select email).toArray
Dim bademails() As String = (From email As String In readText Where Not validEmail(email) Select email).toArray

The OP seem to be at a very basic level, so using Linq wont help him, unless he doesn't care about learning and just copy-paste the code

Solution 2

Use List<t>[^] instead of an array so

C#

List<string> badEmail = new List<string>();
List<string> goodEmail = new List<string>();
for (int i = 1; i < readText.Length; i++)
{
    if (validEmail(readText[i]))  // check valid
    {
        badEmail.Add(readText[i]); // Are you sure this should be a bad email?
        m++;                       // the method name validEmail, would seem
    }                              // indicate that it's a "good" email.
}
