Email Deliverability Expert Needed to Recover 60K Ecommerce Subscriber List

We are seeking a senior email deliverability expert with 10+ years of experience recovering and scaling ecommerce email revenue. This role will diagnose inbox placement issues, sender reputation, list quality, Omnisend configuration, Gmail/Yahoo/Outlook performance, and customer engagement decay. The ideal candidate can rebuild deliverability, segment and reactivate inactive subscribers, improve lifecycle flows, and recover revenue from a large existing email list without damaging sender reputation. Experience with ESP migration, domain/IP warmup, spam complaint control, suppression strategy, and ecommerce retention is required. This is not a basic email marketing role; we need someone who can turn a low-performing 60k subscriber list into a profitable, compliant retention channel.
