need smtp service to send mails

Hey there... I do targeted one-on-one email marketing via Microsoft Outlook. Looking for the smartest, cheapest outgoing SMTP solution to allow me to send these emails while preserving deliverability rates. Wasn't planning on sending any more than a few thousand emails a day, but I read on another post that it's best to limit mails to under 200 an hour. Is this true? Is there a workaround? If there's not, then I'd likely only be sending around 1,000 a day. Any advice or recommendations would be much appreciated.

PS: I see Amazon SES and Mailchimp's Mandrill are right up my alley, and I like the pricing structure. Does anyone have experience with them? Are they very touchy about spam complaints?

You can probably just use google, I think their limit is 2000 a day. Of course if your email is spammy and they figure it out that could be a problem if you need the account. Do you have hosting? Most hosting comes with free emails and usually the smtp limits are over 1000 per day.

Thanks for the replies.
I can use a google SMTP with a custom domain?
I have sendgrid on another domain, which I love, and I set up another domain - the one I plan on using for the emailing I'm discussing - and tried to enroll with Sendgrid, but they shut me down at provisioning.
