people saying they are not getting pricing but they open the emails

I have a flow where a prospect can will out a form and we send them a link to our price sheet. It is done with a flow and then a series of 3 emails. Every email has a huge button with the link to go to the web page with the pricing.

I can not figure out why some say they never got the pricing yet I can look at their profile and see they are opening all the emails multiple times. I even have the link as a button image and text link. Some the data says they clicked it. THe weird thing too is most of the time I can see they opened and clicked multiple times. (See Below)
