Do I need to configure cron on my server with the CRON URL in Queue Process when using ACYMailing Sending Service?
Are there documentation detailing the Sending Service (setup)?
You can use both manual and automatic sending regardless of the sending service you are using. For the automatic sending, cron is used to trigger your Acymailing.
