Remote or Warsaw | Full-time
We are building and scaling a high-volume, performance-driven newsletter portfolio and we are looking for a Senior Email Marketing Manager to fully own newsletter growth, engagement, retention, and monetization. This is a role for someone who understands newsletters as a revenue channel, not just a publishing task — and who is driven to make ours the best in their categories, beating every competitor on engagement and quality.
You will work closely with writers and designers to ensure every send is optimized for opens, clicks, retention, and revenue while maintaining strong editorial quality. You will also own the part of this that most people get wrong: deliverability.
Your primary mission: own 7 to 10 newsletters to start, drive their engagement and retention to best-in-class levels, and scale the portfolio beyond that as you prove the model. This is an IC role with room to build a team around you as the portfolio grows. We are looking for a proactive contributor who is comfortable pushing the limits — someone who is not satisfied matching the competition but determined to beat it. If you treat email as a growth engine and you have the deliverability chops to protect it at scale, this role was built for you.
WHAT YOU WILL OWN
Engagement, retention, and newsletter performance
Own engagement and retention as the primary KPIs of the role — opens, clicks, and active subscriber rates are what you live and die by
Own end-to-end newsletter strategy, publishing, and optimization across the full portfolio, starting with 7 to 10 properties
Relentlessly find new ways to make our newsletters the best in their categories — study what competitors do, then do it better, and find the angles they have not thought of
Optimize subject lines, preheaders, layouts, CTAs, and content flow against engagement, retention, and revenue
Build and run retention programs that keep subscribers active and reduce churn over the full subscriber lifecycle
Maintain consistent, high-quality publishing schedules across every newsletter — nothing slips, nothing goes out late
Review, QA, and approve all outgoing content before it sends — zero tolerance for broken links, typos, or formatting errors
Deliverability and sender reputation
Own deliverability end to end — inbox placement, sender scores, bounce management, and domain health across all sending infrastructure
Monitor deliverability at the ISP level: know the rules and thresholds of each major provider, watch complaint rates independently per ISP, and pause or throttle sends by ISP when the data demands it
Manage sending domains, IP pools, warm-up schedules, and authentication (SPF, DKIM, DMARC) with precision — no cowboy sends, no shortcuts
Diagnose and resolve deliverability issues yourself before they become crises — authentication failures, spam trap exposure, blacklisting, FBL complaints — without deferring to platform support
Use engagement data to protect inbox placement: know when to use openers versus clickers, how to manage sending to engaged versus dormant segments, and how to keep reputation strong across a high-volume portfolio
Stay ahead of inbox provider algorithm changes and compliance shifts that affect delivery
Where cold email is used for growth or partnerships, keep it on completely separate infrastructure from newsletter sending — protecting warm deliverability is non-negotiable
List health and hygiene
Own list quality as a strategic asset across all properties — suppression management, re-engagement campaigns, sunset policies, and ongoing hygiene
Design and execute re-engagement programs that recover dormant subscribers without damaging sender reputation in the process
Build segmentation logic that ensures the right messages reach the right subscribers at the right time
Set clear quality thresholds for subscriber health and act on them — know when to clean and have the discipline to do it
Monetization and adve
