My requirement is to send single email with To/Cc/Bcc added. All the email Ids belong to internal users.
Initially, when I was passing the User.Id to these methods, I was hitting the Single Email Limit Exceeded error.
email.setToAddress(user1.Id); email.setBccAddress(user2.Id); email.setCcAddress(user3.Id);
To get around this limit, I figured out that when User's Id is passed to setTargetObjectId method then the email sent is not counted against daily limit of 5000 emails.
email.setTargetObjectId(User.Id) // to be used instead of setToAddress()
Now, after sorting the problem for setToAddress, I am unsure around how to still include anything equivalent to cc & bcc emails of internal users.
Appreciate any suggestions/recommendations ?
