Survey Integration

It seems like there's not any Sage CRM - Emarketing/Swiftpage Integration for Survey Results. Are they any other providers that Sage CRM integrates well with? Ideally we would like to send out a survey and have the response matched with the email it was sent to, it doesn't seem like Sage E-Marketing/Swiftpage allows for this Unique ID relation.

Please let me know if I'm missing something!
