Hey guys, if I am collecting emails and sending, how do I make it so I never send to the same email address again the next day? Is this what a supression list is? I really hope there is a way to do this! I use Outlook if that matters at all.
In order to help you, we need to know a little bit more about how you are sending and collecting your emails.
A supression list is an internal black list (i.e. people you know not to email). It's used if you have multiple offers/lists and send out a lot of email, you run the filter each time you are about to do a big send so that you don't spam certain people (i.e. people that you know will report you for spamming, etc). As for how to not send to the same person the next day - don't use Outlook. Outlook is a personal mail program, not a mass mailer. You need to look at something bigger like AWeber, PHPList (free), Email Marketer (this is a really cool one), or build a custom platform.
