Sorry, we've taken so long for the next round of e-mail but we went through some design changes and functionality changes with the whole concept of getting bitcoins for opening & clicking emails now.
We also run on getting advertising for it for which we require the 'pool' reach 5 btc till the next campaign
as you can see it is at : BTC
So for a small bit of bitcoins from multiple advertisers you will be able to reach the 400 + active bitcoin members we currently have for your bitcoin related service or product.
If you have any questions don't hesitate to PM me, e-mail me: email@example.com
or reply below.
