Hm, can I know which particular post is this and also, which e-mail is this?

Here is one example from a feed import. There are seven of these emails that are the same. The link on the email goes to here https://authorsdb.com/blog/paula-hirtle-updated-a-blog-post

You can see duplicate emails in Mail Activity

i will continue your issue on your original thread -> https://stackideas.com/forums/easyblog-feed-import-issues
