How MessengerOS grows your revenue
From first visit to repeat customer — one platform handles the whole journey.
-
01
Capture
Collect leads with signup forms, popups and landing pages — or import your existing list and we'll help you clean it.
e.g. An exit-intent popup offers 10% off and adds the visitor to your list.
-
02
Automate
Every new subscriber enters flows that run on their own: welcome series, abandoned cart recovery, follow-ups and win-backs.
e.g. The welcome email goes out instantly; two days later, a reminder with their discount code.
-
03
Convert
Send campaigns on email, SMS or WhatsApp — whichever channel converts best for each customer.
e.g. The discount is expiring — a short WhatsApp nudge turns the subscriber into a first order.
What our Customers are saying
Every day, our goal is to keep our customers happy.
After we started sending out these newsletters, we quickly saw real results.
After we started sending out these newsletters, we quickly saw real results. We got three orders right from our existing subscribers. Email marketing has become a key part of how we reach our customers now, and I’d recommend Teodor to anyone looking to start with newsletters or make their current ones bring in more sales.

Co-FounderOur Newsletter results have been improved
Once the strategy was in place, Teodor crafted several templates for us and taught us how to improve our designs. This support allowed us to independently create and send out newsletters with content that has a higher conversion rate.

More people started opening our emails, which really improved our revenue.
Teodor went beyond just making a good email marketing strategy; he focused on getting more people to open our emails, giving us both a plan and the tools to make it work. With his help, we set up our newsletter system properly, making sure it matched our marketing goals

Frequently Asked Questions
What channels does MessengerOS support?
Email, SMS and WhatsApp, all from one platform, one contact list and one set of reports. You can run each channel on its own or combine them in the same automation, so a customer who ignores an email can get an SMS reminder two days later instead.
What's the difference between the platform and your services?
The platform is the software. You log in, build your campaigns, automations and forms, and send them yourself. Services means we do that work for you: strategy, copy, design, setup and sending, inside the same platform.
Most clients pick services because they are short on time, or because they would rather have marketers run it than learn a new tool. Others use the platform on their own and call us when they need a hand. You are not locked into either. Plenty of clients start with services and take the work in house once the flows are set up.
Can MessengerOS integrate with my Shopify or WordPress site?
Yes. MessengerOS connects with WordPress, WooCommerce, Shopify, Stripe, Tally and Make. That means orders, customers and form submissions flow into your lists automatically, so abandoned cart and post purchase automations work without manual exports. Through Make you can also connect thousands of other apps, and if something is not on the list, ask us.
How does pricing work for SMS and WhatsApp?
SMS is sold in packages. You buy a bundle of messages and use them across campaigns and automations. WhatsApp is billed at Meta's own per message rate plus €0.10 per message sent. Meta's rate depends on the destination country and the message category, so we will give you a per market estimate before you launch.
What is WhatsApp marketing and is it allowed?
WhatsApp marketing means sending promotional messages (offers, launches, cart reminders, restock alerts) to customers who have agreed to hear from you on WhatsApp.
Yes, it is allowed, as long as it is done through the official WhatsApp Business Platform, which is what MessengerOS uses. Meta's rules are strict but straightforward: contacts must give explicit opt-in, and any promotional message sent outside an active 24 hour conversation has to use a message template approved by Meta in advance. What is not allowed is bulk sending from a personal number or the free WhatsApp Business app, which breaks WhatsApp's terms and usually ends with the number banned.
Do you offer a free plan or trial?
We offer a trial period so you can test the platform with your own list before committing. We do not offer a permanently free plan. Every new account gets real onboarding support from our team, and that time has to be paid for somewhere. We would rather charge a fair price and actually help you get set up than hand you a free account and leave you to figure it out.
Can I bring my existing list, or switch from Mailchimp, Klaviyo or Brevo?
Yes, and we will do the heavy lifting. We handle the migration for you, including contacts, segments, templates and automations. We also clean the list on the way in, so you do not carry old bad addresses into a new platform and hurt your deliverability from day one. Opt-in status and consent records come across with the data.
Is MessengerOS GDPR compliant, and where is my data stored?
Yes. All data is stored on servers in the EU, and the platform is built around GDPR requirements: one click unsubscribe, data export and deletion on request.
