Adapt my outreach email so that it doesn't go to spam folders

I need the following email to be adapted so that it doesn't go to the spam folder of email addresses:


Hello,

I’m Sylvia and I’m writing to you from www.usedbooksearch.net, a free tool for finding the best price on used books online.

We would love to contribute to X and we would like to know if you accept articles to your site? We have a team of specialised content writers who are on hand to write interesting and unique articles.

We would also be open to other forms of collaboration. If you have any suggestions, then we’d love to hear them!

If this sounds interesting, then please do get in touch.

Many thanks,
Sylvia
