After you have created at least one e-mail template, you can also prepare it directly for sending. It is not absolutely necessary to send the e-mail directly. You can also create an e-mail planning. Click on "Prepare to send" on the corresponding e-mail template. For better orientation you can name the sendouts.
For example: "1st Sendout Friday".
Below you can choose whether you want to send the e-mails now or at a later time.
If you choose "Send later", you can choose exactly on what day and at what time the e-mail should be sent.
It is also possible to decide to whom the e-mails should be sent.
