They don't care whether or not you delete the ads. They want you to conform the web to their views and what they think should be on the web. Here is a snip from the email:

Pausing or deleting an ad or ad group that advertises a site will not affect or improve the site's landing page quality. The only way to improve poor landing page quality is to correct the site according to our Landing Page and Site Quality Guidelines; after you have done this, please contact Google AdWords support by replying to this email so that we can re-evaluate your site's landing page quality.
