I think this is one of the reasons I started using rss2email back in the day - I could do the filtering, searching, and manipulation using my preferred email client.

Originally that would have been mutt, later my own client, and later still I switched to gsuite.

I did add support for excluding entries/posts based on title, body, regular expression, and similar, but at the end of the day I just fetch all feed entries and save them as emails. The later processing can be done by any client and that's pretty flexible. There's very little custom processing required in the RSS-processing itself.
