how to get topic rss into my email inbox?

RSS feeds are made to be read by RSS feed readers and services. You’ll need to subscribe to a service that emails you updates of your RSS feed. Like https://www.kbcafe.com/rss/rss2smtp.aspx or https://www.bloglines.com/ .

Alternatively, you could install and activate this plugin and then subscribe to your blog: https://www.skippy.net/blog/2005/02/17/subscribe2

RSS isn’t meant for an email inbox. It is meant for an RSS reader program.

thankyou for the hints.
i have signed up with all of the above.
i still do not know how to get the “RSS fee for this link”

the most success so for with bloglines.
i still cannot get a feed for this topic though i can get it for another topic.

Have you checked out services like Bloglet or FeedBlitz, which can take an RSS feed and create an email subscription? I haven’t looked into their ability to handle specific categories/topics of a WordPress blog, however.

thankyou all i understand what to do with RSS now
