I didn't write the below code, and am very new to understanding it.

I have a situation where an Apex job is designed to deliver multiple emails to an email contact at 5, 10, 15, and 30 days after the contact has been created. If the first email at 5 days post-contact creation is not sent, does that mean that the emails that are supposed to be sent at 10, 15, and 30 days will also not be sent by that same Apex job?
