Setting up a schedule for your mailing time is great for sorting out the messages you want to send and when.
1) In the dashboard, click Mailing List.
2) In Mailing List, click +Send New Message or Reuse a message you already sent.
3) In the General Details, click the dropdown list under Schedule Mailing Time and choose Immediately or Custom.
4) If you choose Immediately, the message will be sent as soon as you hit send at the bottom of the page.
5) If you choose custom, a line will appear where you can choose the date and time of day you want your message to be sent.
6) Once you have set everything else the way you want, hit the green send button.
