What is the difference between a conditional wait and hard wait in the journey builder?

A  conditional wait  is a wait within an 'IF' button, So.. if this happens during this timeframe then proceed to the next step - if it doesn't not then proceed to the ELSE condition or EXIT

A likely scenario could be:

IF email is opened in 5 days then ALERT colleague. ELSE send email again.

We strongly advise against using a conditional wait for CRM evaluations as you cannot trigger a journey with a manual CRM evaluation (you CAN use this for an action such as a form fill or email open and then add a CRM evaluation after if needed)

A  hard wait  inserts a delay between your trigger and your response. This can either be date specific (e.g wait until December 25th) or day specific (e.g wait 5 days)
