I setup the token-based survey which will have around 2000 participants that will receive invitation. Since our server has 500 outgoing emails per hour limit, I wonder how do i send emails out. Do I need to:
1) manually select batches of 500 emails and send them out at different time or
2) is Limesurvey has some other way aka internal engine enabled that will sends email out with the specified rate to stay under provider limits?
