Within the client dashboard, select "edit" in the contact information box
Within the email box, select "+ Email" under any primary, or secondary, contact you are wanting to add an email to.
When a contact has multiple email addresses, you will see the option to switch which email is set to default
Once you have saved the new email address and edited any settings, scroll up and hit save. You're done!
NOTE: If an existing client enters a different email address during their online reservation process, Gazelle will merge new or missing email addresses to the existing client record.
