Mailchimp no longer needs an SPF include: it uses its own return-path domain. DMARC alignment comes from DKIM.

DKIM: CNAME records at k2._domainkey and k3._domainkey pointing at dkim2.mcsv.net and dkim3.mcsv.net.

A domain can have only one SPF record. If you already send through another service, add the include to your existing record rather than creating a second one, and keep the total under 10 DNS lookups.

Once SPF and DKIM pass, add a DMARC record at _dmarc with p=none and a reporting address, read the reports for a couple of weeks, then move to quarantine and reject.
