I'm having a slight problem which I would love to automate if possible. I have multiple email signup forms on my site which are all integrated into their specific Mailchimp lists - however I would like all these signups to be automatically placed into my Mailchimp master list. I've tried to do this with Zapier, but it requires a new Zap per list and really don't want to keep doing it manually. Has anyone else had this problem? I've got a growing number of email lists so would love to sort it out.
