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.

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.

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
