The first thing to understand when creating an email sequence is your email schedule. Your email schedule can be found in settings under the schedule tab.
The email schedule feature determines when it's appropriate for us to send emails on your behalf. You can adjust your email schedule at an account and sequence level. If you don't have a custom schedule for each of your email sequences, your sequences will follow the default email schedule in your account settings.
Below you can see how your email schedule appears in your account settings. You'll see the timezone that your email schedule is based in, the default email schedule and the holidays feature.
To prevent emails from being sent during U.S. holidays, toggle the holidays feature on in your settings.
You can adjust the timezone for email sequences on either an account or sequence-specific level. If you don't set a custom timezone for each sequence, your emails will follow the default timezone set in your account settings.
