## You can not use the contact form to send e-mail advertisement
The contact form does **not** give you any email address. Thus, due to a technical limitation, you are not able to put such an address down in your mailing list. And here the legal problem starts: Under CANSPAM the e-mail address is the only thing the user needs to offer as the identifier to stop receiving any e-mails.

Since you can not put any address down in a mailing list, you can not implement a functioning unsubscribe link. Since you can not implement a functioning unsubscribe link, you can not fulfill the requirement of CAN-SPAM. Since you can not obey the law, you can not send advertisements via the form legally.
