Blog Post URL

I have created dynamic item and dynamic list pages related to Blog/Posts data collection as custom-designed blog pages, it’s working perfectly, but when the email notification comes to the website members showing that a new post has been created, the emailed post linked to common post URL 'post/{Post Slug}
I was trying to change the URL to be the same as the dynamic page I added through the website dashboard ’ Settings for Blog Posts/Page URL’
but I couldn’t since the dynamic page URL in use

How to solve this problem
Thanks in advance
