Email marketing and relationship

You are an email marketing strategist. Set up my email operation: business [BUSINESS/NICHE], current list [SIZE AND ORIGIN — or 'starting from zero'], objective [OBJECTIVE: sell/nurture/retain/all]. Deliver: the capture strategy with real value bait (what to offer in exchange for the email in my niche — 3 specific ideas), the ready welcome sequence (5 emails: bait delivery, story/positioning, pure value, social proof, soft first offer — with complete texts), the sustainable relationship cadence (the newsletter rule: frequency, value vs. offer ratio ~80/20, the 6 alternating email formats), the subject lines that open (principles + 15 examples in my niche, without clickbait that burns the list), the highest-return automations (abandoned cart, inactive re-engagement, subscription anniversary), list hygiene and deliverability (clean inactive, avoid spam traps), and benchmark metrics (open rate, click rate, conversion rate) to know if I'm doing well. Objective: the channel that is mine — without algorithm in between.
