Mainly look at who your ads are being sent to.
1. If they are being sent to complete strangers, new prospects that you've not had dealings with before, then your ad should not mention the program, but rather ask them to request the information from you. Once you receive this request, take a note of the email address and first name (at least), and store them in a file (preferably a Group Mailer). You can then email these people back (because they are now an optin lead) and advise your website details, etc. . . . .
2. If they are being sent to your previously spoken to clients, no problem.
3. If they are members of the same club or program as you, and cross promotion is permitted, again no problem.
It is imperative to avoid SPAMMING that you include a DISCLAIMER CLAUSE at the foot of every email you send out. (Safelist advertising has its own so no need for one there).
The Disclaimer Clause should say something to the effect:
DISCLAIMER: This email cannot be considered SPAM as you have previously requested information from me.
DISCLAIMER: This e-mail is sent in compliance with strict anti-abuse and NO SPAM regulations. Your address was collected as a result of either posting to a link, a free classified ad, or you have sent me your business proposition by e-mail in the past. Under Bill S1618 TITLE III, passed by the 105th US Congress, this message cannot be considered SPAM as long as there is a way to be removed, paragraph(a) (c) of S. 1618.
DISCLAIMER: Please refer to www.spamlaws.com/federal/hr3113.html This message is sent in compliance with the pending new Email bill, Section 301. paragraph (a) (2) (c) of S.1618.
It is also imperative to avoid SPAMMING that you include a REMOVAL CLAUSE at the foot of every email you send out. (Again safelists are not necessary to do this with).
The Removal Clause should say something to the effect:
REMOVAL INSTRUCTIONS: If you no longer wish to receive emails from me, please click “Reply" to this email, and type or copy and paste in the subject area - REMOVE ME FROM YOUR EMAIL LIST.
You may like to categorize your Email list, to relate it to your own lists. I have several different lists, I always categorize the list.
Check out that you don't SPAM.
