Hey there! Unfortunately, our registration emails can get caught up in spam folders. My first recommendation would be to check you spam folder to see if our email was routed there. The next step would be to whitelist meraki.com and meraki.net to ensure future emails are delivered to your inbox.
If your customers continue to have trouble receiving our emails, please have them email our team at webinar@meraki.com. We can help them troubleshoot on a case-by-case basis!
