Please provide the exact trigger you're using. CB Reconfirm Email fires the normal profile update trigger so the below trigger should be fine to use.

onAfterUserUpdate

You'll also want to use the below trigger if you want it to work in backend too.

onAfterUpdateUser

Move CB Reconfirm Email to be ordered before CB Auto Actions then within your action under Parameters enable Reload User. Next under Conditions ensure the email even changed with the below condition.

[var1_email] Not Equal To [var3_email]

That should get rid of any oddities of it working against old emails or email addresses that aren't confirmed yet.

It should only fire if the email changes. Since you're using reconfirm email it basically should never fire for a profile edit update, but only after they've confirmed the change. Your action probably should be configured as follows.

Global
Triggers: onAfterUserUpdate
Type: Usergroups
User: Automatic
Access: Everybody
Conditions
1: [var1_email] Not Equal To [var3_email]

If that condition isn't working right you can try the below instead.


You can add your other conditions after you're sure it's working for your usage. You may or may not need to use Reload User. Sorry, I've never used the usage you're trying nor is the above tested. Adjust as needed. Note you can access URL variables with [get_VARIABLE] so worst case you check that the action is being fired on the confirm email page using its URL variables.
