Email mail merge

Hi, The email templates start with this format, "Hello [contact first name]". When, say, select a contact and define an email campaign, does the [contact first name] get replaced with the contact first name or not? I am not really sure where I can check. Thank you!
Yes, that is a short code that fills in with the information of the contact you are emailing. There are other shortcodes on the left side that you can use as well. You should create a contact for yourself in the CRM and send emails to yourself to test.
