Good news: Queryfeed now produces W3C-valid RSS feeds. That means you are welcome to use them with IFTTT service!

Here is a screenshot from the IFTTT dashboard. It shows an applet that reads a feed from Queryfeed and sends me emails:

ifttt-applet

And here what I’ve got in my inbox:

ifttt-mail

I hope you’ll enjoy the feature.

Thanks,
Ivan.
