In the letter I stated that I am a former researcher at the Pasteur Institute, did mouse lifespan tests, I am in contact with the authors of the paper, and have starting with a few mice at home.

That's why I think that the key thing is to use our existing contacts, otherwise it may sound like spam.

Well, that does sound impressive enough.
