About Customer.io

Over 8,000 companies — from scrappy startups to global brands — use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive. We help teams send smarter, more relevant messages using real-time behavioral data.

About the Role

We’re looking for a Deliverability Consultant to join our growing Deliverability and Technical Support organization. In this role, you’ll help customers achieve world-class inbox placement, maintain stellar sender reputations, and navigate the evolving email ecosystem.

You’ll collaborate closely with Customer Success, Support, and Engineering to diagnose complex sending issues, advise on best practices, and develop strategies that improve engagement and sender health at scale. This is a technical, customer-facing role that blends data analysis, troubleshooting, and strategic consulting—all in service of ensuring our customers’ messages reach the right inbox, every time.

What We Value

  • Empathy and curiosity: You approach every customer with patience, understanding, and a desire to dig deeper.

  • Clarity: You simplify complex technical concepts and help others do the same.

  • Collaboration: You thrive in cross-functional partnerships and see customer outcomes as a shared goal.

  • Operational excellence: You bring structure to how we monitor, troubleshoot, and improve deliverability—without overcomplicating the work.

  • Continuous learning: You stay ahead of evolving standards and see change as an opportunity to improve.

  • Customer impact: You focus on practical solutions that make a measurable difference to customers’ performance.

What You’ll Do

  • Act as a trusted deliverability advisor—providing both reactive and proactive consulting on sending performance and reputation management.

  • Conduct detailed deliverability audits, including authentication (SPF, DKIM, DMARC, BIMI), DNS configurations, and infrastructure setup.

  • Monitor sender reputation data across IPs and domains using tools like Google Postmaster Tools, Microsoft SNDS, and Validity Everest.

  • Diagnose and resolve deliverability issues such as blocklists, spam traps, and engagement drops.

  • Partner with Product and Engineering to identify systemic deliverability trends and influence roadmap priorities.

  • Build educational content (articles, webinars, internal guides) to share insights across teams and with customers.

  • Provide strategic IP warming and inbox placement guidance for high-volume senders.

  • Collaborate with Customer Success to create long-term deliverability improvement plans for key accounts.

  • Stay current on new regulations and standards (Gmail/Yahoo sender requirements, CAN-SPAM, GDPR, TLS-RPT, and more).

What We’re Looking For

  • 2–4 years of experience in email deliverability, ideally at a B2B SaaS company, ESP, or marketing automation platform.

  • Deep understanding of email authentication (SPF, DKIM, DMARC, BIMI) and infrastructure (SMTP, MTAs, DNS).

  • Proficiency with deliverability monitoring and analytics tools (Everest, Postmaster Tools, MXToolbox, or similar).

  • Strong analytical skills and the ability to translate complex datasets—bounces, engagement metrics, blocklist data—into clear recommendations.

  • Excellent written and verbal communication skills, able to simplify technical concepts for any audience.

  • Collaborative, empathetic, and customer-obsessed mindset.

Bonus points for:

  • Familiarity with emerging frameworks like AMP for Email and BIMI.

  • Participation in deliverability communities (M3AAWG, ESPC, etc.).

  • Experience supporting cross-channel engagement (SMS, Push, In-App).

Why You’ll Love This Role

Email deliverability is the backbone of Customer.io’s success. Your expertise ensures that every message our customers send reaches the right inbox at the right time—driving meaningful engagement and ROI. You’ll help scale our deliverability program, define internal best practices, and contribute to thought leadership within the global deliverability community.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1

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.
