We're the team behind your email program.

Experienced, grounded, and built for the long term.

Two decades of building trust

Built on email. Shaped by relationships.

The people who built Vertex came from the earliest days of commercial email, and we did something most agencies don't do: we stayed focused. No pivot to social. No chase after the next channel. Just email, done well, for organizations that needed it done right.

What held the company together wasn't a product or a platform. It was the relationships. Clients came to us with complex programs and stayed because we learned those programs inside and out, often knowing the systems, the workflows, and the audiences better than the clients themselves. That kind of embedded partnership is hard to manufacture. At Vertex, it developed naturally, and it became the thing we are known for.

We have also never stood still. As email evolved from batch-and-blast to sophisticated lifecycle programs, we evolved with it. We moved into new platforms before clients had to ask. We built expertise in tools like HubSpot, Salesforce Marketing Cloud, iPost, and Braze as they became the infrastructure of modern email programs. We didn't just keep up with the industry. In the categories we focus on, we helped shape what good looks like.

More than two decades later, that is still the work. The platforms are more complex. The programs are more demanding. But the commitment to doing the work well, showing up consistently, and treating every client's program as if it were our own has never changed.

What Vertex Values

How we show up


Care

We are empathetic, human, and welcoming in how we work with clients and each other. Good work starts with genuinely giving a damn.

Trust

We are dependable and reliable. We follow through on what we say we will do, every time, without being asked twice.

Quality

We are thoughtful and intentional. We take pride in doing the work well, not just getting it done.

Partnership

We are collaborative and committed to shared success. We're not a vendor you manage. We're a partner you rely on, and that distinction shapes everything about how we work.

Community

We value connection and groundedness. A family-oriented culture shapes how we show up for our clients, our team, and each other every day.

Founded in 
Frederick, Maryland.

Recognized as a historic market and industrial center since the 1700s, Frederick, Maryland has always been a place where people build lasting foundations. The roots of Vertex are here, and that means something to us. The way this company has always worked reflects where it came from: grounded in relationships, built for the long term, and more interested in doing the work well than making noise about it. We operate remotely and work with organizations across the country. But the values that shaped this company came from here, and they haven't changed since we started running complex email programs in 2002.

How We Work

Three things that define every client relationship.

    We embed, we don't orbit.

    We integrate directly with your team, your tools, and your workflows. You won't manage us from a distance.

    We follow through, every time.

    Consistency is the job. We own the details so your team doesn't have to track them down.

  • yellow warning icon of an exclamation point

    We treat your program like it's ours.

    Your email program is infrastructure. We approach it that way, with the same care and accountability we'd bring to our own.
