I've been working with the Postman Agency for my email marketing needs, and I must say, it's been a journey that's well worth it. It did take a few goes to align the emails with my personal style, but patience paid off. The team listened, adapted, and now they've got it just the way I like.
What I appreciate most is their dedication to following instructions. They've become an integral part of my business's success, helping it grow through effective email marketing. I have gained so much extra time and I'm excited to see where we go from here.
Their regular check-ins and updates on the reporting side are great. It's reassuring to have a partner who keeps you in the loop.
If you're looking for a reliable partner in email marketing, I highly recommend the Postman Agency.

I've tested countless email agencies. Some started strong, others fell flat. That all changed with Postman. They've delivered consistent results across 7- and 8-figure brands I manage.
What sets them apart is their operator mindset. They don’t just execute—they test, optimize, and evolve. Their segmentation, strategy, and campaign quality are unmatched.
Every brand I referred has stayed with them. If you're serious about retention and real revenue growth, Postman is the real deal.

Professional, knowledgeable, reliable, attentive, available and creative are just some of the words that come to mind. We were initially apprehensive about using them as we need emails written in Norwegian, but after talking to Sami, we gave it a try.
With an impressive learning curve, they managed to produce convincing emails in our language while learning our weird products, customers, and brand.
The quality of the craftsmanship and data-driven advice is top level, without a doubt. Shoutout to Sami, Leonardo, and the team!

Great experience working with the Postman Agency. They evaluated our existing email structure and gave us a score and outline for improvements, then quickly implemented their strategies.
Our main point of contact, Claire, was wonderful to work with and ensured a smooth transition.

Campaigns
- Campaign revenue tripled after we implemented advanced segmentation and A/B tested new messaging angles.
- Using Shopify & Google Analytics, we identified the client’s highest-converting send times (which they were not using) and A/B tested them against their original assumptions—resulting in a clear winning schedule.
- Our psychology-driven angles unlocked record-breaking results: one campaign alone generated €10,000, compared to their previous high of €4,000, despite offering a lower discount.
Flows
- By applying learnings from campaigns, filling missing gaps, and optimizing existing flows, we achieved a 50% uplift in flow revenue—capturing quick wins and driving long-term consistency.
Result: A complete turnaround in just 3 months, setting a new benchmark for both campaigns and flows performance.

FREQUENTLY ASKED QUESTIONS
Questions & Answers
What brands like yours ask us before scaling retention.
How is Postman different from other agencies?
Postman is not a "do-it-all" agency—we live and breathe email marketing. With 300+ eCommerce brands served and millions in revenue generated, our specialized approach focuses solely on retention marketing. Every solution is customized to your brand, backed by our results guarantee, so you know we're fully invested in your growth.
What's the price?
Our monthly retainers range from $1,600 – $5,000 USD, depending on your project scope. For brands who prefer a smaller engagement, we also offer one-time flow setup projects. In both cases, your investment is backed by our performance guarantee.
Am I qualified to work with Postman?
We partner with ambitious businesses generating $30K+ per month that are ready to invest in scaling. If you're serious about growth and want a retention engine that compounds revenue over time, you're qualified.
Do you require a long-term commitment?
No. All of our agreements are rolling month-to-month. We don't lock clients into long contracts because we'd rather you stay with us for results—not paperwork.
What is your results guarantee?
Before we start working together, we'll provide you with a FREE audit (if your brand qualifies). During this audit, our team will review your account, identify untapped revenue opportunities, and create a detailed action plan with clear KPIs.
We then back it up with our Process Guarantee:
👉 If we don't achieve the KPIs outlined in your contract, you'll receive a full refund.
Is it only one person that manages my account?
Not at all. You'll have a dedicated in-house team of 4 specialists:
- Senior Email Designer
- Client Success Manager
- Email Marketing Specialist
- Copywriter
Your team works closely with you on strategy, execution, and optimization—every day.
Why hire Postman instead of hiring in-house?
Hiring in-house is expensive, time-consuming, and risky. With Postman, you instantly gain access to a full-stack retention team with decades of combined experience—at a fraction of the cost. We already know what works across industries and can start generating results faster than it would take to onboard one new employee.
How fast do you move?
Speed is our edge. You'll have your strategy finalized and first email draft within 3–5 business days. From there, we scale up execution quickly so you're not waiting around for results.
