A Shopify store owner sent a newsletter 5 days after migrating their DNS to Shopify, and multiple customers reported receiving a “This Connection is Not Private” security warning when accessing the site.
Root Cause:
The SSL certificate has not fully propagated across all users yet. SSL certificates enable HTTPS encryption, securing data transfer between web servers and browsers. Without proper SSL, connections remain unencrypted via HTTP, triggering browser security warnings.
Recommended Solution:
Timing Issue:
The newsletter may have been sent too early in the migration process, before SSL propagation was complete across the user base.
I recently moved to Shopify (DNS) about 5 days ago and I did a newsletter to my customers and a bunch of them are complaining that they are getting this
Maybe I sent off our newsletter too early. Why would they be seeing this with Shopify?
All feedback appreciated

Hello @wooflinen 
Looks like the SSL certificate is not yet fully propagated to all users. I think it should work fine after some more days.
Hello Wooflinen,
Thanks for reaching out to the community!
The error ‘this connection is not private’ highlights that the website’s SSL (Secure Sockets Layer) certificate is not up to date, which makes the connection insecure for the users.
All you have to do is acquire or update the website’s SSL certificate, which enables encryption and secure sharing of data between web servers and web browsers via Hypertext Transfer Protocol Secure (HTTPS). However, without the certificate, data is shared and encrypted via HTTP, which leaves the web traffic at risk, and show them this error.
Hope it helps!
