The emails are failing the DMARC alignment check:
During this check the domain used in the From: header (algolia.com) is compared to domains in successful DKIM (mail2.mcsignup.com and mandrillapp.com) and SPF (mandrillapp.com). They do not match so DMARC fails. You probably want to use the domain mandrillapp.com in the From: address.

Anyone ever come up with a solution to this issue? I've just started implementing DMARC and I'm getting SPF alignment fails for mcsignup.com as well.

I am dealing with this issue right now and have come up with the following, the way Mailchimp does return path is not compatible with DMARC and will fail every time. The provided DKIM and SPF are valid but that is not the domain DMARC checks against.

I am investigating why this customers open rates have gotten so low and nothing has changed on DNS so I am left wondering if this is related or not. Regardless I see this as a problem.

I have other customers that use Mailgun and their DMARC comes back clean so I am probably going to test there with this client.

MailChimp uses their own domain in the MAIL FROM address on the SMTP envelope (a.k.a. return-path) to handle bounces. So any client/server doing an SPF check will check their SPF DNS record (not yours) so the raw SPF check passes. But it will not be the same domain as your From header and therefore it will not pass the SPF alignment check that DMARC does. For DMARC to pass either your SPF domain or the DKIM domain must align with the From header. So if you have properly set-up DKIM, that will align and DMARC passes.

Hi All,

We had this issue, I was able to fixed it today. All you need to make sure is you have SPF, DKIM mailchimp updated in your DNS records and also domains are Authenticated in Mailchimp. Earlier our domains were just verified not authenticated, once we authenticated, emails started passing DMARC as well.
