Director, Email Deliverability

Job Description

Postscript is the AI messaging platform trusted by 20,000+ Shopify brands — including Brooklinen, Ruggable, True Classic, and Dr. Squatch. With a mission to make SMS your number one revenue driving channel, we built the best-in-class SMS marketing platform and launched revenue-driving AI features not available on any other platform. And we're just getting started.

Key Responsibilities

• Deliverability Strategy & Sender Reputation
• Own Postscript's end-to-end email deliverability strategy — IP pool architecture, domain strategy, and shared vs. dedicated sending models.
• Design and manage IP and domain warming programs that get new senders to volume quickly and safely.
• Establish and enforce authentication standards (SPF, DKIM, DMARC, BIMI) and DMARC alignment across customer sending domains.
• Monitor sender reputation, inbox placement, and blocklist activity, and lead rapid remediation when issues arise.
• Keep Postscript ahead of evolving mailbox-provider requirements — Gmail, Yahoo, and Microsoft bulk-sender rules, spam-rate thresholds, and one-click unsubscribe.
• Customer Deliverability & Advisory
• Serve as the senior deliverability expert for our brands — auditing programs, diagnosing inbox-placement issues, and building remediation plans.
• Translate complex deliverability concepts into clear, actionable guidance that marketers can act on.
• Own escalations, partnering with customers to protect and grow their inbox placement and sending reputation.
• Cross-Functional Collaboration & Foundation-Building
• Partner with Product and Engineering to build the deliverability tooling, monitoring, and infrastructure that power the platform — and influence the roadmap with deliverability requirements.
• Build the playbooks, processes, and standards that scale deliverability across thousands of senders.
• Establish feedback loops (FBLs), Postmaster Tools, and reporting that give customers and internal teams visibility into deliverability health.
• As the function matures, hire, mentor, and lead a team of deliverability specialists.
• Industry Expertise & Compliance
• Maintain expert-level knowledge of the deliverability landscape and represent Postscript in the broader community (e.g., M3AAWG, emailgeeks).
• Build and steward relationships with mailbox providers and industry partners.
• Ensure Postscript's sending practices and customer programs stay compliant with CAN-SPAM, GDPR, and mailbox-provider policies.
• Leverage AI tools and internal systems to scale deliverability monitoring, diagnostics, and customer guidance.

What We'll Love About You

• 8+ years of dedicated email deliverability experience, ideally at an ESP, CDP, or high-volume sending platform (e.g., SendGrid/Twilio, Attentive, Braze, Klaviyo, Iterable, Validity/Return Path).
• Deep technical command of email authentication (SPF, DKIM, DMARC, BIMI), IP and domain warming, sender reputation, and feedback loops.
• Hands-on experience owning deliverability for bulk/high-volume senders, including diagnosing and remediating blocklistings and inbox-placement problems.
• Fluency with Google Postmaster Tools, Yahoo Sender Hub, and the 2024+ Gmail/Yahoo/Microsoft bulk-sender requirements.
• Existing relationships with mailbox providers and/or active participation in the deliverability community (M3AAWG, emailgeeks, etc.) strongly preferred.
• A consultant's instinct — you can translate deep technical detail into strategy that non-technical marketers understand and act on.
• Player-coach mindset: happy to do the hands-on work today and build the playbooks (and eventually the team) for tomorrow.
• Strong understanding of e-commerce/DTC brands and how email drives revenue (e-commerce experience strongly preferred).
• Comfortable building from scratch in a fast-paced, early-stage environment, with a growth mindset toward AI and emerging tooling.
• Outstanding written and verbal communication skills, with high reliability and outstanding follow-through.

What You'll Love About Us

• The chance to build a function from the ground floor and define how 20,000+ brands reach the inbox.
• A high-growth startup environment with opportunities to make a meaningful impact and grow your career.
• A fully remote work culture – work from anywhere.
• A fun, collaborative team passionate about e-commerce and innovation.
• A flexible paid time off policy to recharge and prioritize your well-being.
• A comprehensive health, dental, vision insurance package.
