In your Email Account settings, you can now find a new delay settings option - Random delay. When you choose this option, you can set a minimum and maximum delay time (for example between 10 and 30 seconds), and emails from this account will be sent within these times. This will help your account look more human to ESPs and can potentially improve your deliverability. Please note, the minimum and maximum values you can choose are 5 and 3600 seconds.
