Director, Email Deliverability

Postscript is the AI messaging platform trusted by 20,000+ Shopify brands — including Brooklinen, Ruggable, True Classic, and Dr. Squatch.

We built the best-in-class SMS marketing platform and the revenue-driving AI features no other platform offers — and now we're bringing that same obsession to email. As we expand into a true multi-channel platform for high-growth DTC brands, getting every message to the inbox is mission-critical.

Backed by Greylock and Y Combinator, fully remote since 2018.

Job Description

As the Director, Email Deliverability at Postscript, you'll own the strategy, infrastructure, and sender reputation that get our customers' email to the primary inbox. This is a foundational, hands-on leadership role: you'll build Postscript's email deliverability function from the ground up — IP and domain architecture, authentication standards, reputation monitoring, and mailbox-provider relationships — while serving as the trusted deliverability advisor our brands rely on as they migrate and scale their email programs on Postscript.

You'll partner closely with Product and Engineering to shape the deliverability tooling and infrastructure our platform is built on, and with Customer Success and Support to keep our customers' programs healthy. You'll set the standard for how 20,000+ brands reach the inbox — and as the function grows, you'll build and lead the team behind it.

This is a fully remote position and can be based in the US or Canada.

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.
  • Lead deliverability onboarding for brands migrating their email to Postscript, including reputation transfer and warming strategy.
  • 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.
  • High-growth startup environment with opportunities to make a meaningful impact and grow your career.
  • Fully remote work culture – work from anywhere.
  • Fun, collaborative team passionate about e-commerce and innovation.
  • Flexible paid time off to recharge and prioritize your well-being.
  • Comprehensive health, dental, vision insurance.

Postscript Demographic Questions and Categorizations

At Postscript, we are committed to creating an inclusive workplace that values diversity. We firmly believe that companies diverse in, for example, age, gender identity, race, sexual orientation, ethnicity, and perspective are better because of it. However, even beyond that belief, we simply want to strive for what's right.

For this reason, we are asking candidates to voluntarily self-identify through a few demographic questions. Our purpose in collecting this information is to help us assess our outreach efforts and diversity representation goals. Your responses will not be linked to your identity or your application, and neither recruiters nor hiring managers can see this information at an individual level. Your responses are stored in the aggregate and will not play any role in our hiring decision.  Your decision to participate or not participate in this survey will have no impact on your candidacy at Postscript.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
