Email Deliverability
ericrisco/rsc-harnessUse when mail already sent lands in spam, is rejected, or fails the Gmail/Yahoo bulk-sender checks and the fix is authentication and reputation, not the sending code: SPF/DKIM/DMARC alignment, domain warmup, spam-complaint rate, one-click unsubscribe, BIMI. NOT putting mail on the wire through a provider API (that is `email-connector`).
At a glance
This skill is for DevOps & Infrastructure and helps you fix emails landing in spam, set up spf/dkim/dmarc records, and warm up a sender domain.
