I want more users

Hello, 208 people is not enough, and i have so much customers from my business.
How can i add (via SQL) a list of people to my Boonex website?

Waht ois the code... I have a list with 1500 Email adresses and is the second column again E-mail adresses.
Then i want send via mais mail that i gonna send to everyone each month a newsletters (that is people i know)
if thay don't want receive a newsletter they can delete their account on Busimatch. 

Yes, possible to do this; of course you should first ascertain if the people want to be on your site.

pay them to join your site :p ok ill help you. tell them get free dinner at certain restaurant if they add 100 friends to your website. Go to some restaurant who need marketing and want to grow their business. ask them to pay you to promote their restaurant. They will get customers, you will get users and users will get discounted dinner ;) Every body happy  :D you can replace restaurant with any business who need marketing.

Lol, but i have a business (a printshop) 
They receive now a newsletter....

But i pay for it via:

Now i want that all these people receive the newsletter directly via the site. How to do that :-)

email all of them from  no-reply or admin email of your website and tell them this is your business website. and now customers can directly book orders by chat in real time for free. get samples  to choose etc..man be creative put some stuff on your website related to your business. they will automatically start using ur website to contact you. introduce live chat option.

Nothing pisses people off more than having to opt out of something they never asked for in the first place.  If you want to keep those customers, you should keep that in mind.  If you start adding them to a website without their permission, and sending them a newsletter (AKA spam) that they didn't sign up for, you'll lose more business than you gain. 

Probably the thing that would piss them off the least, would be to offer them incentive via email.  The incentive would be available after joining your site.  You could put something like a free download in an email template, or have a members only page with free offers.
