What this skill does
Email Systems Email has the highest ROI of any marketing channel. $36 for every $1 spent. Yet most startups treat it as an afterthought - bulk blasts, no personalization, landing in spam folders. This skill covers transactional email that works, marketing automation that converts, deliverability that reaches inboxes, and the infrastructure decisions that scale. Principles Transactional vs Marketing separation Description: Transactional emails (password reset, receipts) need 100% delivery. Marketing emails (newsletters, promos) have lower priority. Use separate IP addresses and providers to protect transactional deliverability. Examples: Good: Password resets via Postmark, marketing via ConvertKit Bad: All emails through one SendGrid account Permission is everything Description: Only email people who asked to hear from you. Double opt-in for marketing. Easy unsubscribe. Clean your list ruthlessly. Bad lists destroy deliverability. Examples: Good: Confirmed subscription + one-click unsubscribe Bad: Scraped email list, hidden unsubscribe, bought contacts Deliverability is infrastructure Description: SPF, DKIM, DMARC are not optional. Warm up new IPs. Monitor bounce rates. Deliverability is earned through technical setup and good behavior. Examples: Good: All DNS records configured, dedicated IP warmed for 4 weeks Bad: Using free tier shared IP, no authentication records One email, one goal Description: Each email should have exactly one purpose and one CTA. Multiple asks means nothing gets clicked. Clear single action. Examples: Good: "Click here to verify your email" (one button) Bad: "Verify email, check out our blog, follow us on Twitter, refer a friend..." Timing and frequency matter Description: Wrong time = low open rates. Too frequent = unsubscribes. Let users set preferences. Test send times. Respect inbox fatigue. …
