Apply for a valid hosting account (quite a few good providers in SA) with your own virtual email server with your own .co.za domain name (located on the hosting provider mail server) just make sure they have not had their IP blocked by spamcop.net
http://www.spamcop.net/bl.shtml
Some receiving email servers do the following checks:
* Reverse DNS lookup to see if that is a valid IP for your domain or a ADSL IP
* Lookups on Spamcop servers.
1. Provide an opt out option
2. Provide address and other contact details on the email at the very least.
3. Say "you are receiving this news letter because you subscribed to www.mywebsite.com"
Thanks andytl5 that is extremely important and as he said in point 1, have an unsubscribe option
Do not buy these bulk lists as they are not legit, and that constitutes spamming
and you will get a bad name as a spammer.

5 ELECTRONIC MAIL
Your service with SAIX includes the ability to send electronic mail via the SAIX mail relay service (SMTP). Misuse of the SMTP service may result in blacklisting of the user id. The following examples are non-exclusive and are provided for guidance to customers.
Use of your e-mail account to send unsolicited bulk (UBE) or commercial messages (UCE) is prohibited. This includes, but is not limited to, bulk-mailing of commercial advertising, informational announcements, charity requests, petitions for signatures, and political or religious tracts. Such material may only be sent to those who have explicitly requested it.
Using your e-mail account to collect responses from unsolicited bulk or commercial e-mail is prohibited.
Sending mass unsolicited mail or deliberately sending very large messages or files to one or more recipients ("mail bombing") is prohibited.
Forging or removing e-mail headers is prohibited.
Use of e-mail to harass or intimidate other users is prohibited. Harassment, whether through language, frequency of messages, or size of messages, is prohibited. Sending a single unwelcome message may be considered harassment. If a recipient asks to stop receiving e-mail from you, you must not send that person any further messages.
You may not forward or otherwise propagate chain letters, whether or not such messages solicit money or other items of value, and whether or not the recipient wishes to receive such mailings.
SAIX services may not be used to collect replies to messages sent from another ISP, where those messages violate this Acceptable Use Policy or the Acceptable Use Policy of the other ISP.
SAIX reserves the right to delete messages or files which have remained on its servers for excessive periods of time as determined by SAIX, in its sole discretion.
