How do I delay an Opolis E-Mail or fix a certain end-date maturity?

In general Opolis E-Mails are immediately available to the authorised Recipient upon pressing the button Send. However, you may also decide that a certain Opolis E-Mail may only become available for the Recipient as of a certain point of time. Clicking on the small date icon on the right side allows you to determine when an Opolis E-Mail shall become available by the Recipient. You can also decide how long an Opolis E-Mail may be valid and can be opened and read by the authorised Recipient.
