Here you can set up delivery orders. You can then keep working or even close the browser, the emails will be sent in the background, up to 900 emails can be sent per hour for each organiser. A recipient can be written to every 12 hours at the most for each designated survey. If the last email for this survey was sent more than 12 hours ago, the email address passes over to the participant group.
In the case of surveys with an access code participants who have already completed the survey will no longer receive emails. So for surveys with access codes you can send reminder emails to participant groups by setting up an email text and creating various delivery orders for the entire participant group.
