Hi there,

Huge fan of your content here!

Anyway - to keep this short. Could you please let me know if this is a right address for and editorial inquiry?

If not, I would appreciate if you can direct me to the right one.

I know that  has a great potential an a real base of visitors so I would really like to start a collaboration with you. Could you tell me if you would be willing to accept any type of guest post, editorial or or other form of  link placement?

Seeing that it's pretty hard to match your writing style, I think it would be a lot better if you could include a link to our website into a new or even older article of yours, for a fee.

If this sounds like something you could do, simply reply to this email, tell me your guest post or external link policy and the price to have our website promoted on yours, and let's make a deal! :)

Thanks,
Lora Stonden
