name: email-marketing description: When the user wants to plan email marketing, EDM, newsletter strategy, or email deliverability. Also use when the user mentions "email marketing," "EDM," "newsletter," "SPF," "DKIM," "DMARC," "email deliverability," "email content strategy," "email campaigns," "newsletter strategy," "email automation," or "cold email." For signup UI, use newsletter-signup-generator. metadata: version: 1.0.1

Channels: Email Marketing

Guides email marketing strategy for AI/SaaS products. Email ROI ~$36 per dollar spent; open/click rates typically higher than social. Covers EDM vs Newsletter, five content types, deliverability (SPF/DKIM/DMARC), and SEO synergy via article delivery.

When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for audience and content strategy. See content-marketing for content types and formats across channels.

Identify:

  1. Goal: Retention, conversion, brand reach, or SEO synergy
  2. Content mix: Onboarding, campaign, announcement, features, newsletter
  3. List size: Bulk sender rules (5,000+/day) require Gmail/Yahoo compliance

EDM vs Newsletter

TypePurposeUse
EDMDirect marketing; conversion-focusedPromotions, campaigns, announcements; bulk sends
NewsletterOngoing value; relationshipIndustry insights, curated articles; regular cadence

Combine both: EDM for push; Newsletter for nurture. Cover different stages and goals.

Five Content Types

TypeUse
OnboardingWelcome + first-use guidance; 5-7 day sequence; behavior-triggered; drive "Aha!" moment
CampaignPromotions, limited-time; conversion or participation
AnnouncementProduct launch, major update; one-time important notice
Features updateNew features, improvements; help users adopt
Blog/NewsletterCurated articles, industry insights; sustained touch

User Best Practices

PracticeGuideline
PersonalizationSegment by behavior, source, stage; boosts open/click
TimingNew users: dense; existing: controlled pace; behavior-triggered > calendar-only
Welcome seriesSend soon after signup; 5-7 emails over days; guide first key action
UnsubscribeOne-click required (Gmail/Yahoo); honor within 48h; clear entry
Complaint rateKeep below 0.3%; list hygiene critical

Content Best Practices

PracticeGuideline
SubjectOne clear topic per email; avoid pure promo
Value firstUseful info before promotion
CTASingle primary CTA; clear next step
Mobile50%+ read on mobile; responsive layout, tappable links

Deliverability & Domain Config

Subdomain: Use subdomain (e.g. mail.example.com) for marketing; keep transactional (support@, etc.) on main domain. Isolate risk.

SPF, DKIM, DMARC

ProtocolPurpose
SPFAuthorizes mail servers for domain
DKIMCryptographic signature; verifies sender
DMARCPolicy for unauthenticated mail; start p=none, then quarantine, then reject over 60-90 days

Order: SPF first, then DKIM, then DMARC. Gmail/Yahoo require all three for bulk senders (5,000+/day) since Feb 2024.

Advanced: TLS-RPT, MTA-STS, BIMI (brand logo). Postmaster Tools: Monitor deliverability, spam rate, auth status.

Delivery Strategy: Articles + SEO Synergy

Article TypeUse
RetentionDeep content for existing users; improve retention
ToFuTop of funnel; awareness (trends, concepts, problem framing)
MoFuMiddle of funnel; consideration (comparisons, reviews, best practices)

Dual value: (1) Better email engagement (open, click, stickiness); (2) Drive traffic to article pages from non-search channel; signals to Google that users value content; supports SEO.

Measurement: GA4 email source traffic to article pages; GSC rank/click changes.

Planning Framework

  1. Content mix: Allocate onboarding, campaign, announcement, features, newsletter
  2. Select articles: Pick retention, ToFu, MoFu from blog; prioritize SEO target pages
  3. Cadence: Stable frequency (weekly/biweekly/monthly); avoid over-sending
  4. Monitor: Open rate, click rate; GA4 email contribution to article traffic; GSC

Frequency

Peak timesTue-Thu, 8-11am or 2-4pm (recipient timezone)
