You may have created a new group of contacts in your account and you have started to draft a new email campaign. You select that new group but you are seeing 0 (zero) contacts added. Why can that be?
A: Your contacts need the contact preference for email in order to be selected successfully for an email campaign or email step action within an automated campaign.
So the quickest way is to action an "Update Many Contacts" on your group. Just go via Contacts > Update Many Contacts and follow the on-screen instructions.

Make sure on the contact preferences section to tick the relevant box on the left AND the Yes radio button option on the right.
Then in a few seconds your group will have the correct contact preference and you will be able to add them successfully to your email campaigns!
Hint: When you are importing your contacts in bulk, make sure to tick all the relevant boxes for contact preference.
