Email Verification Help

Hey, I've got some mules, probably only like 40 of them.
Now they need emails verified.

How did you guys go about verifying yours?
Just using temp mail accounts or using a script or what?

Just trying to figure out an easy way to get this done, sorry if there has already been several threads about it, I looked for a simple solution among other threads.

Thanks.

Options:
1) Buy 99c go daddy domain and use email forwarding
2) Use temporary email service
3) Set up email domain with someone like 000webhost
4) Make accounts yourself

One Gmail account can have any number of mule accounts linked to it.

I have a program to read in from a file a list of mule account email address’s and their associated passwords ,the program automatically selects each mule individually and registers the mule account with a second email (the second email address is automatically generated by the program) while also sending the email verification to the new email address. there is a new file with a list of the mule accounts with their new emails address’s and associated passwords. (I still need to code this first),(this only work with mule accounts created before the new email verification system).

I then use a second program to automatically find and send back the email confirmation links to activate the accounts.
