Many Companies and Organizations have webinars and online meetings where they’ll provide rewards for attending their webinars. Below I’ll provide a list of upcoming webinars where you can earn free stuff, usually gift cards. In most cases you will have to attend the webinar online until it ends, and sometimes they’ll make you do something like an exit survey before you get your gift.
Since they’re professional events, you will have better odds of getting the gift if you can use a professional/business email address instead of something like a gmail. Business name and titles are often required as well. I’ll continue to update this post as I find more of them, the new webinars will be in bold with each update:

• • J2 Cybersecurity Fundamentals on August 29 at 1PM: $50 Amazon Gift Card
  • Creating Smarter, Safer Buildings Using Cloud-Based Access Control on August 29 at 1PM: Apple Airtag and Yeti Cup
  • XPOSURE VIRTUAL SUMMIT on September 10: Uber eats gift card -first 100
  • Enhancing Your Customer’s Experience Through Bandwidth Aggregation on September 18 at 2PM: Amazon Gift Card
