Autoresponder emails: What time of day are the emails sent?

If I set-up an Autorepsonder email to be sent on a later date and that date is today, will the email still be sent?

Is there a way to send emails "now" to all the responders?

It is based on the submission time and an additional 1 hour to that time. Unfortunately, there is no option to force send the timed autoresponder in the settings. If you'd like this option, I suggest creating a new thread for that.
