Design pattern suggestions for reading and parsing related methods for emails using java Mail API?

I am currently working with selenium and I am using JavaMail API (v. 1.6.2) to retreive mails and parse them for the following uses, e.g:

1. Extract the account confimation link.
2. Extract the account confirmation code.
3. Extract the link for account deletion.
4. etc...

As you can already infer, I am doing it to automatize certain online account procedures such as account creation and deletion and so on.

First I thought of creating keywords for each and every methods and use them but since there are going to be email session objects, this wouldn't be a nice way to create a new email session object on every single method call.

So if anyone has ever done somethign similar to this, do you have any suggestions for using specific design patterns?
