Ask YC: What is the best solution for managing user email lists?

Constant Contact is the one I use and offer to my clients. The main reason is I personally get a higher delivery rate (instead of getting caught in spam filters) and their email creator wizard is awesome. Try out their 60-day free trial: http://email.volcanicmarketing.com

Other solutions out there are:

* iContact http://www.icontact.com - Their customer service sucked when I tried them out.

* Campaign Monitor http://www.campaignmonitor.com - I've heard good things about their reports but their delivery rates have not been as great as Constant Contact in my email campaigns.

* Exact Target http://www.exacttarget.com - Great for enterprise companies. They will cost at least $10k/year

* Vertical Response http://www.VerticalResponse.com

* SilverPOP http://www.silverpop.com Another enterprise solution with a big cost.

Thanks guys much appreciated - the key thing has got to be getting through the spam filter

Ok am going to try using groupspaces ...

mailman? I think that accepts the unsubscribe emails too...
