Hello
My name is Duarte, I am contacting you on behalf of M5ads.com, in order to establish an advertising partnership. 
We want to advertise on your website with a banner.
We pay upfront (pre-payment), so you won’t risk anything!
If you are interested in hearing our proposal, please get in touch. We are always receptive to suggestions in order to get a good deal for both parties.
Graciously
