Postman Agency and the team have been amazing to work with, their communication is amazing and they really dig deep to understand your business and being able to showcase it in regular newsletters is truly amazing! Highly recommend and worth every $$$$
Great team, great company, great results, Competitive rates.
Two brands went from less than 10% of total revenue from email to over 26%. LTV grew by 30% after we implemented our strategies.

As a fractional CMO working with multiple 7- and 8-figure eCommerce brands, I’ve tested countless email marketing agencies over the years—some promised the world, others had a good start but quickly fell off. That all changed when I introduced my clients to Postman.
After struggling with agencies that lacked strategy, accountability, or the ability to drive real revenue growth, my clients finally found a partner that delivers. We’ve now been working with Postman for over three years, and the results speak for themselves. Their approach is performance-driven, proactive, and deeply strategic. From advanced segmentation and data-backed flows to highly optimized campaigns, they’ve consistently increased customer retention, lifetime value, and overall revenue.
What truly sets them apart is their team. They don’t just execute—they think like operators, constantly testing, optimizing, and refining strategies to ensure peak performance. The level of attention they give to each client is rare in this industry.
I’ve now recommended Postman to multiple brands, and every single one has stayed with them. If you’re an eCommerce brand looking for an email & SMS partner that actually moves the needle, stop wasting time with agencies that overpromise and underdeliver—Postman is the real deal.
Looking forward to many more years of working together!
We’ve been working with them for a year and have significantly increased both LTV and AOV

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. At the outset, it did take a few goes to align the emails with my personal style, but patience paid off. The team at Postman Agency 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.
Moreover, 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 and provides insights into the performance of your email campaigns.
If you're looking for a reliable partner in email marketing, I highly recommend the Postman Agency. Their commitment and adaptability make all the difference.
The results were immediate: sales went up, traffic surged, and their team impressed us with clear communication and sharp, well-executed strategies.

Working with Postman Agency has been exceptional for ETHOS Media. As our partner for email marketing, they delivered top-notch campaigns that exceeded expectations. The Postman Agency team is professional, reliable, and attentive. They understood our client's needs and provided regular updates, making the process seamless and efficient. Their commitment to excellence is evident in every aspect of their work. Thanks Sami, Leonardo and the team.
We've had a great experience working with Postman Agency. They really took the time to understand our branding and helped refine our brand image across our email campaigns and flows, which were severely lacking visually.
They always have new ideas for content to share/promote, and have been patient throughout our revisions. Everyone we've worked with has been super friendly and nice to meet with, meetings are efficient and the team always does what they say they will! Highly recommend them for your email marketing needs, no matter where your business is based.
I've been working with them for years and they have helped my business grow in a way that I did not expect. They have done a fantastic job creating and managing my email and SMS flows and campaigns. I highly recommend Postman.

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 a different language (Norwegian), and we were being spammed by tens of other agencies wanting to do our email marketing, but after talking it through with Sami, we decided to give it a try.
With an impressive learning curve at an impressive pace they managed to produce convincing emails in our language that only required minor quality check. And this was at the same time as getting to know our weird products, our customers, our brand and how we would like to communicate to produce on-point email content.
The quality of the craftsmanship and datadriven nature of their decisions and advice is top level, without a doubt. Shoutout to Sami and Leonardo and the rest of the team. Great work!
I was blown away by how well they captured my brand voice and adhered to the brand design guidelines
Remy @ MoxyPatch
Postman Agency helped our brand with email automations, and it was a seamless collaboration. They are true experts in their field, advising us on the best design solutions, cadence, and flows to implement and test.
They made valuable observations and improvements along the way, not only to our automations but also to our day-to-day campaigns. As a result, we’ve seen our channel sales grow. We definitely recommend working with them.
Great Team to work, very easy, super responsive and great communication, as well very well organised. Was easy to communicate and work with team, recreate the flows, polish the e-mails and reached the goals of our target in less than 2 months, definitely recommending.
The Postman Agency continues to be a fantastic partner. Email marketing is critical to our company's success and our ongoing connection with our customers. The Postman Agency has done a brilliant job of making this aspect of our marketing tasks and goals easy and successful.
They completely understand our brand's voice and bring a wealth of knowledge and best practices. They have improved all of our email marketing metrics. I have no hesitation in recommending them to other companies looking for a professional team of email marketers to work with.
Unlike our previous experience with email agencies, Postman didn’t overpromise and underdeliver — they actually exceeded expectations and overdelivered
Gilad @ yona.com.au
Working with Postman Agency has helped us really push email marketing to the next level.
We've seen an uplift in sales via emails and the volume and quality of the emails has been exceptional, plus they're really nice, it's great working with them!
Great experience working with the Postman Agency. I love that they evaluated our existing email structure and gave us a score and outline for improvements, then quickly and expertly implemented their strategies. Our main point of contact, Claire, was wonderful to work with and ensured the project remained on track and our transition went smoothly.
After working with several agencies with limited success, Postman stood out. They deeply understood our customers and leveraged our competitive edge, which led to outstanding success.

Frequently Asked Questions
Questions & Answers
What brands like yours ask us before scaling retention.
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.
Our monthly retainers range from $1,400 – $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.
We partner with ambitious businesses generating $40K+ 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.
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.
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.
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.
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.
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.
- Ongoing Email Marketing: End-to-end, fully managed retention strategy and execution (campaigns, flows, SMS, deliverability).
- One-Time Flow Setup: A complete foundation of high-converting flows, delivered in 30 days, with no ongoing retainer required.
