I need to set up an email list for my past freelance clients, and for potential future clients, to keep them up to date with news and offers, and basically to make sure I keep reminding them that I exist.
I have a main freelance site, and I have a site dedicated to the more specialist area I write in. Should I have sign-up boxes on both sites for one central list, or should I have separate lists for the main site and the specialist site?
One list would obviously be easier to manage, but two would be more targeted. Does anyone have any experience in doing one or the other, and have any advice?
