A list of IDs of the contacts, leads, or users to which

must be of the same type (all contacts, all leads, or all users).

Type: Void
Usage
You can list up to 250 IDs per email. If you specify a value for the targetObjectIds field, optionally specify a whatId as well to set the email context to a user, contact, or lead. This ensures that merge fields in the template contain the correct data.
Do not specify the IDs of records that have the Email Opt Out option selected.
All emails must have a recipient value in at least one of the
following fields:
- toAddresses
- ccAddresses
- bccAddresses
- targetObjectId
setWhatIds(whatIds)
Optional. If you specify a list of contacts for the targetObjectIds
field, you can specify a list of whatIds as well. This helps to further
ensure that merge fields in the template contain the correct data.
