I’m looking for a very flexible Email Marketing Software/Service. Preferably a hosted solution, like GetResponse, or Aweber.
I have tried a lot of them, but none of them seem to fit my needs.

Here’s what i need:
1. Autoresponders (aka Follow-up Emails or Trigger Mails)
2. Ability to send an email immediately after subscription AND after profile update.
3. Ability to use custom fields in message body and subject (for personalization)
4. Ability to filter and segment my list based on custom fields. For example, I want to send a specific autoresponder e-mail to only subscribers who live in Texas. Or only to women over 35.

(Note: it’s ok if these requirements can only be achieved using API)
