View on GitHubWhat This Skill Does
Covers email deliverability, DNS authentication (SPF/DKIM/DMARC), compliance with CAN-SPAM/GDPR/CASL, webhook handling, retry logic, and accessibility. Includes a transactional email catalog for planning which emails an app needs before writing code.
It pulls together scattered email knowledge (authentication, compliance, deliverability, accessibility) into one reference instead of piecing it together from RFCs and provider docs.
When to use it
- Setting up SPF, DKIM, and DMARC records to stop emails from landing in spam
- Planning the full set of transactional emails a new app needs before writing any code
- Adding double opt-in and consent tracking to a newsletter signup form
- Building retry logic and idempotency keys for reliable email delivery
- Fixing accessibility issues like missing alt text and poor contrast in HTML emails
