autoresponders custom date faq field fields insert integrated integration listed mailchimp page party signup third won

Hi,

I recently integrated with mailchimp -- unfortunately, autoresponders won't work unless I can insert the date of signup as a custom field into it...

Is there a way to do that?

The only fields that can get sent to a third party with our integration are listed on our Integration FAQ page:
