Hi Sahil,

Can you try something like below.

  
String casedesc =  'Customer Name: Smith Ng Customer Email: smith.ng@.com';
String s2 = casedesc.substringBetween('Customer Name:',' Customer Email:');
string s3=casedesc.SubStringAfter('Customer Email:');
system.debug('name'+s2);
system.debug('email'+s3);

If this solution helps, please mark it as best answer.

Thanks,
​​​​​​​
