Google/ring until you find emails for the correct people. Phoning up first can’t hurt. Phoning up afterwards can’t hurt either.
Somewhere like a local paper is probably gagging for news. You can might be able to email anyone and it’ll find its way through. Ditto certain websites. Bigger national titles aren’t and you’ll often need to get it to the correct person yourself.
Make it easy for the people you email. Get to the point quickly. Don’t add multiple attachments they have to wade through. Make sure what you send them isn’t full of errors. Put simple contact details – eg for more info, pictures etc contact (email, phone).
Don’t be too sad if you get totally ignored. (But chase them up if you do.)
