These really re-affirm my suspicions.

Have a phone number doesn't make a business seem any more credible. Sure, people do outreach, cold calling, etc, but it's a real long-shot unless you have a verifiable reputation to back it up.

 

Here's a tip -- when the first five words are broken Engrish, it's a scam... though I'm a bit shocked to see quite so coherent a use of English on that type of mail.
