Unlike automated emails, broadcast emails are set up and sent manually. Broadcast email is when you send an email to everyone on your list or your entire customer base at the same time. This type of email isn’t really automated; You still have to press the “send” button. However, you can set it up in advance to send the email at a specific date and time. Automated emails, on the other hand, are triggered by a user action, an event on a website, a time delay, or any other condition you set.
