Featured Guest Authors
Waqar Habib Khan
Full-Stack Developer & Designer
Waqar Habib Khan is a seasoned full-stack developer and designer with expertise in building scalable SaaS applications, e-commerce platforms, and fintech solutions. Over the past decade he has shipped more than 100 production projects and helped generate over $2M in client revenue, working across the entire stack from database design and API architecture to front-end performance and conversion-focused design. His day-to-day toolkit centers on React, TypeScript, Node.js and cloud-native infrastructure, and he has a particular interest in the unglamorous parts of software that make products reliable: email deliverability, transactional messaging, authentication flows and abuse prevention. At Temp Postal he writes about the practical side of developer productivity — how to test signup flows without polluting real inboxes, how disposable email fits into a modern QA pipeline, and how small teams can adopt privacy-friendly tooling without slowing down. When he is not shipping client work he contributes to open-source projects and writes detailed build logs on his personal site, where he documents the trade-offs behind real architectural decisions rather than idealized tutorials.
David Okonkwo
Enterprise Security Consultant
David is an enterprise security consultant with 15+ years of experience helping Fortune 500 companies implement robust email security practices. He specializes in compliance frameworks and risk assessment, and has led SOC 2, HIPAA and ISO 27001 readiness programmes for organizations in healthcare, finance and SaaS. His consulting work regularly touches on the questions Temp Postal's enterprise readers care about: when is a disposable email address acceptable inside a regulated environment, how should development and QA teams handle test accounts without creating shadow IT, and what do auditors actually look for in an email-handling policy. David writes for Temp Postal as a guest contributor, bringing the buyer's perspective to topics like vendor risk assessment, data-processing agreements and retention policies. His articles are deliberately practical — comparison tables, checklist-style compliance breakdowns and direct answers about where temporary email fits and where it absolutely does not, such as anything involving protected health information or financial account recovery. He holds CISSP and CIPP/US certifications and speaks regularly at regional security conferences about pragmatic compliance for small engineering teams.
Yuki Tanaka
Privacy Engineer & Researcher
Yuki is a privacy engineer and researcher focusing on email anonymization techniques and metadata protection. She has published several peer-reviewed papers on privacy-preserving communication systems, including work on metadata leakage in webmail clients and the deanonymization risks of seemingly harmless message headers. At PrivacyLabs Tokyo she designs systems that minimize the data a service needs to collect in the first place — an approach she brings to her guest writing for Temp Postal, where she explains the technical side of anonymous email without requiring a computer-science degree. Her articles cover topics like what information an SMTP transaction reveals even when the message body is encrypted, how retention policies differ between providers, and why 'no logs' claims deserve careful reading. Yuki is also an active contributor to open-source cryptography tooling and occasionally reviews Temp Postal's own infrastructure choices from an outside perspective, which the team publishes unedited. She believes the most important privacy feature is not any single technology but a provider's willingness to document exactly what it stores, for how long, and why.
Temp Postal Team
Sarah Chen
Lead Security Researcher
Temp Postal
Sarah is a cybersecurity expert with over 10 years of experience in email security and privacy protection. She leads security research at Temp Postal, where she studies how disposable email services are abused by spammers and fraudsters — and how to stop them without punishing legitimate users who simply want to protect their primary inbox. Before joining Temp Postal she worked on anti-phishing systems for a major email provider and spent several years in incident response, investigating business email compromise campaigns that almost always began with a throwaway address. She has contributed to multiple open-source privacy projects and regularly reviews the GDPR, CCPA and data-retention implications of the features the team ships. Her writing focuses on threat modeling for ordinary people: what data a signup form actually exposes, how email tracking pixels work, and when a temporary address is the right tool versus when a full alias service makes more sense. Sarah believes privacy tools should be boring, predictable and honest about their limits, and she holds every Temp Postal feature to that standard.
Mike Rodriguez
Senior Developer Advocate
Temp Postal
Mike is a developer advocate specializing in API design and developer experience. He helps developers integrate privacy-focused email solutions into their applications, from first API key to production load. Before moving into advocacy he spent eight years as a backend engineer building notification and messaging infrastructure, which is where he developed his conviction that email testing is the most neglected part of the average CI pipeline. At Temp Postal he owns the developer documentation, the REST API reference and the collection of guides that show how to use disposable inboxes for automated signup testing, QA automation and staging-environment verification. He writes the kind of tutorials he always wanted to find: complete, copy-pasteable examples with real error handling, honest rate-limit numbers and clear explanations of what temporary email can and cannot do. Mike also runs the feedback loop between power users and the engineering team, turning integration pain points into API improvements. Outside of work he maintains a small open-source library for polling-based email assertions in end-to-end test suites.
Emma Thompson
Privacy Content Lead
Temp Postal
Emma is a technical writer and privacy advocate who creates educational content about digital privacy, email security, and best practices for staying safe online. She leads Temp Postal's content strategy, which means she is responsible for making sure every guide answers the question a reader actually typed into a search engine — not the question marketing wishes they had asked. Her background is in technical documentation for consumer software, and she brings that discipline to privacy writing: plain language, concrete steps, and no fear-mongering. Emma's guides cover the everyday situations where a temporary email address makes life easier, from signing up for a one-time discount code to testing a service before trusting it with your real address, as well as the broader habits that keep a primary inbox clean and secure. She works closely with the security research team to translate their findings into advice non-technical readers can act on, and she fact-checks every claim against primary sources before publication. Emma is particularly interested in the gap between privacy tools built for experts and the ones ordinary people will actually use.

Write for UsQuick answer
Who writes the privacy and email guidance on Temp Postal?
- Every article is attributed to a named person, not to a generic newsroom byline.
- Technical claims are tested against the live mail platform before publication.
- Regulatory claims cite the source text of the law or the regulator's own guidance.
- Articles carry a visible revision date so readers can judge freshness.
How our editorial process works
A piece starts as a question we see repeatedly in support tickets, search data or developer conversations. Before anything is drafted, we check whether the question already has a good answer somewhere on the site. If it does, we improve that page instead of publishing a near duplicate, which is why the library is deliberately smaller than the content farms competing for the same queries.
Drafting is done by whoever actually owns the subject. Deliverability posts are written by the engineer who maintains the inbound worker. Compliance posts are written by the person who reads the regulations. That constraint slows publication down and is the main reason a post can sit in review for weeks, but it keeps invented detail out of the library.
Review covers three things: is every factual claim reproducible, is every number sourced, and does the article answer the question in its first hundred words. Anything that fails the third test gets restructured rather than padded.
How we test what we publish
When an article says a service accepts disposable addresses, we tried it. When it says a header is present, we captured the header. Screenshots and transcripts are stored with the draft so a later reviewer can confirm the behaviour has not changed, and articles are re-tested when a revision is due.
Numbers about our own platform come from the production database rather than from marketing estimates. When we cannot verify a figure, the article says so plainly instead of borrowing a statistic from another blog that also borrowed it.
Corrections and reader contact
If a published claim turns out to be wrong, we correct the article in place and note what changed at the point of revision. We do not silently delete pages that have become inconvenient, because the links people made to them should keep working.
Readers who spot an error can reach the editorial team through the contact page. Security issues go to the address published in our security policy rather than through general support, so they reach an engineer immediately.
Writing for Temp Postal
We accept a small number of outside contributions each quarter, mostly from engineers and privacy practitioners with firsthand operational experience. Contributors keep their byline and their author page, and are asked to meet the same sourcing standard as staff writers.
Pitches that are really link placements are declined. The write for us page sets out the topics we are short of and the format we expect.
