RSS Feed to Marketo Email & Landing Pages - Using AppScript
Business Issue: Display the most recent blog feed in Marketo Landing pages and Email.
Solution: In this case, I took the example of https://techcrunch.com/feed/ and used the App script to display RSS feed content in the Google Sheet which again can be triggered hourly, daily, and weekly.
Once you pull the data from RSS Feed it will come like below.

Now, you can just update the Tokens specific to each heading. (Title and Link) is updated on an hourly basis.

The final step is to show them on the landing page in Marketo, for this I chose 2 places. TY Page RSS Feed Settings
News Ticker

You can send it to your blog subscriber as well using the Email. Let me know in case if you want to use the service.
