Design a complete, ESP-ready email sequence — per-email subject line options, preview text, body copy with CTAs, send timing, segmentation and branching logic, plus a bulk-sender deliverability checklist (SPF/DKIM/DMARC, one-click unsubscribe, complaint-rate limits). Designs only; it sends nothing. Triggers on "/digital-marketing-pro:email-sequence", "build a welcome sequence", "write a cart abandonment flow", "our emails keep landing in spam", "nurture sequence for trial users". Reads the brand profile, voice, templates, and compliance rules; actual sending belongs to /digital-marketing-pro:send-email-campaign.
