I just ask. Right to the point. spam is long and garbage... ha ha. I get many too.
Greeting,
Im doing a post for my blog on weddings accessories. I would like to blog about your shop. I was wondering if I can use some images from your store for the post?
Here is my blog- link
Cheers,
Kelly
I personally I dont interview, I pick info from their shop/website, etc for my post but if I did I would ask short and sweet too. Then get into questions etc if they accept.
Put image use for blog post in the subject or something of the like. Any one I have asked was very receptive.
