We are launching a new productivity app and need a full email marketing strategy. Could you outline a comprehensive plan covering our content mix across different email categories, the balance between direct promotional pushes and regular nurture newsletters, technical deliverability setup including domain configuration and authentication protocols, how to integrate our blog articles across the customer funnel to support SEO, recommended sending cadence, and key metrics to monitor?

|---------|-----| | EDM | Direct marketing; conversion-focused | Promotions, campaigns, announcements; bulk sends | | Newsletter | Ongoing value; relationship | Industry insights, curated articles; regular cadence |
Combine both: EDM for push; Newsletter for nurture. Cover different stages and goals.
| Type | Use |
|---|---|
| Onboarding | Welcome + first-use guidance; 5-7 day sequence; behavior-triggered; drive "Aha!" moment |
| Campaign | Promotions, limited-time; conversion or participation |
| Announcement | Product launch, major update; one-time important notice |
| Features update | New features, improvements; help users adopt |
| Blog/Newsletter | Curated articles, industry insights; sustained touch |
| Practice | Guideline |
|---|---|
| Personalization | Segment by behavior, source, stage; boosts open/click |
| Timing | New users: dense; existing: controlled pace; behavior-triggered > calendar-only |
| Welcome series | Send soon after signup; 5-7 emails over days; guide first key action |
| Unsubscribe | One-click required (Gmail/Yahoo); honor within 48h; clear entry |
| Complaint rate | Keep below 0.3%; list hygiene critical |
| Practice | Guideline |
|---|---|
| Subject | One clear topic per email; avoid pure promo |
| Value first | Useful info before promotion |
| CTA | Single primary CTA; clear next step |
| Mobile | 50%+ read on mobile; responsive layout, tappable links |
Subdomain: Use subdomain (e.g. mail.example.com) for marketing; keep transactional (support@, etc.) on main domain. Isolate risk.
