Error in welcome flow analytics?

Hi @dgibbs, welcome to the community!

Just note that most of us here are just like you, participating and sharing things we’ve learned - though many Klaviyo team members also participate as well.  So glad to see you here!

A few reasons why you might be getting “clicks” on emails that were never opened.  These reasons for these “phantom clicks” aren’t easy to confirm, or even have official answers, but I'll list some conventional wisdom for consideration:

• Some email clients/programs (or within secure IT organizations) scan email for viruses or try to determine if links are “bad” or contain phishing attempts.  These enterprise tools do “click” on a link (in a secure environment) to check where it goes to make sure emails aren’t going somewhere inappropriate.  So they don’t “open” and email because it’s a robot.
• They way most email providers tracks “opens” literally since the beginning of the internet, is by placing invisible (1 pixel by 1 pixel, often times transparent or empty images) in the email and see if that image is “downloaded” when you open the email.  As you can imagine, lots of organizations block these types of images (by default) for the same reasons for privacy, tracking, or security provisions. 
• Add in the complication with Apple’s email privacy solution, along with other privacy/security tools, there’s always going to be some inaccuracy.  So most “open rates” aren’t always 100% precise - but as you get more and more recipients the variance decreases with a larger sample size.

Now for your own particular case, that is strange that it reports that the email was delivered and opened/clicked on.  Are you using Apple Mail (on mobile), Outlook, or within an Enterprise environment (Google Workspace, Microsoft 365, etc)?
