Could you clarify if you actually have someone that is responsible for reading and responding on the official contact channel (http://ifttt.com/platform) for "Partnership" Inquiries?
I've found that if you ever want to contact a company, find the appropriate person and email them. Collectively owned company emails are terrible because they often don't have a single point of responsibility.
Also for github repos, project maintainers, email if you want a response, don't use an issue or the wiki or form. I just got a minor rails gem updated today that had people complaining about the lack of updates in issues by emailing the account owner.
