We want to send out a survey to 1600 tokens.
Should this be chunked in smaller batches? Should these batches be send with an interval?

throttling invitations it almost always a good idea. Especially if you have recipients e-mail handled by the same server ( kb.mailchimp.com/article/does-mailchimp-...when-sending-emails/ is a good overview,

inside limesurvey you can only configure batch size but not the delay between batches. So you can have an option to throttle manually or use a smtp provider that does it automatically (most bigger providers to - sendgrid, mailgun, critsend, but please check first)
