Drips have good and bad points. Good cuz they're easy. Bad cuz they're usually very prefab and mostly irrelevant.
I have to politely disagree with OCCastles above, though. If you find a great newsletter to send, it doesn't matter whether your prospect believes that you created your email newsletter all by yourself. I promise you, they don't really care. If you send them something of with real value, they'll keep reading it.
Also, any decent email marketing company you go with will have a strict anti-spam policy and "whitelist" relationships with major ISPs. You're more likely to have your personal monthly emails filtered out as spam than a newsletter from a reputable provider.
