Assign two different emails for two different groups (but only one contact)?

Question

Is it possible for one contact to subscribe to two different groups with two different emails – or will CiviCRM always send email to the primary email address?

IOW, is this possible?:

Robert Smith has two emails and is subscribed to two groups:
1. Group A sends to [email protected]
2. Group B sends to [email protected]

Answer 1

You can create a location type for each group - collect emails for that location using a profile.

Then when emailing click options (the spanner icon) for recipients to choose the location.
