I recently sent out a newsletter which contained the latest blog posts and the “unscubsribe” – “view online” link as well.
When clicking on the unsubscribe or view online links, as well as the “read more” links on each blog post within the newsletter I get an error message that says “invalid newsletter”.
This only happens when clicking on the links from within my android phone email client – When I click on the links in Windows 10 Mail program all works as it should.
There are no error log entries and I am unsure how to rectify. Does anyone have any ideas?
Thank you in advance.
