Newsletter Automation

Hello everybody! I have a workflow created in which I add different links to websites, (RSS), and extract the news from the web. Then, the AI agent with ChatGPT selects the news of the last 7 days and the sector I want and generates an email and continuously sends it.

I have a problem and that is that it adds news from more than 7 days ago and also, the link it adds does not exist.

Can anyone help me with this?

Thank you very much.
Best regards,
