Mystic Seaport Museum had the audience. What it needed was a system. Visitor volume was strong. Membership was not keeping pace. The organization was running campaigns, but each one started over. No accumulated learning. No structure underneath. When the campaign ended, the results left with it.
The Challenge

Visitor-to-member conversion was underperforming relative to the audience Mystic had.

The museum welcomed hundreds of thousands of visitors each year. Family attendance was strong, anchored by the LEGO exhibition and a robust seasonal program. But conversion from first-time visitor to paying member was inconsistent, strong in peaks, weak in between, and with no system to close the gap.

The marketing was campaign-driven rather than system-driven. Good work, executed well, but disconnected. A campaign would run, performance would improve, the campaign would end, and the organization would rebuild from scratch the next time. The problem was not effort. It was architecture.

The problem was not effort. It was architecture. Every campaign started over. Together built something that wouldn’t.

What Together Built

A structured membership program built to run, repeat, and grow.

Together built the membership campaign system from the ground up, starting with how the museum’s audiences were defined, and ending with an automation infrastructure the internal team could operate with minimal lift.

Audience Segmentation Framework: visitors categorized by type, engagement level, and membership likelihood, giving the team a foundation for targeted communication.

Multi-Touch Email Conversion Sequence: a structured journey from first visit to membership, with messaging tailored to where each audience segment was in the decision process.

Onsite Conversion Strategy: a visitor journey audit and conversion point recommendations, aligned with how families actually moved through the museum.

Automation Infrastructure: email sequences and trigger workflows built into the museum’s existing platform, designed to run with minimal ongoing management.

Performance Measurement Framework: defined KPIs, tracking setup, and a reporting cadence that gave the team clear visibility into what was working.

The Results

A system the organization owns, uses, and builds on.

Within the first ten weeks on the new platform, the system was already running ahead of plan. New family memberships paced at 167% of the annual goal, well ahead of where the calendar said they should be. Auto-renewal enrollments, starting from zero, nearly doubled in a single month, turning one-time joins into a recurring base that compounds instead of resetting each year.

Email grew into a revenue channel of its own, up 34% month over month. And when paid media launched, it returned more than ten times its cost in the first two weeks. The new microsite changed the quality of every visit, too: average engagement time more than doubled to over two minutes, with visitors moving through roughly five pages per session. The infrastructure is now the museum’s to run, and it is built to keep improving.

What the museum has at the end of this engagement is not a campaign that has to be rebuilt. It is a documented system, a trained team, and a clear view of where to invest next.

Common Questions
How long does a program like this take?

It depends on scope, but most engagements run as a focused sprint. The core system, including the audience framework, email sequences, and automation, is typically built and live within the first few months, with performance compounding from there. The exact timeline is mapped at the outset in discovery, so you know what to expect before the work begins.

Yes. Together builds within your existing platform rather than replacing it. If your current platform has meaningful limitations, that will be surfaced in discovery and options discussed. But the goal is always to build something your team can operate from day one, using tools they already know.
No. The framework scales to the organization. What matters is that you have an audience worth converting and a team capable of running the system once it is built. Together has worked with organizations ranging from regional institutions to national-scale museums. The scope of the build adjusts to fit. The approach does not change.
Everything. The audience segmentation framework, the email sequences, the automation workflows, the performance measurement setup, and the full Marketing Playbook documentation are yours. Together hands everything over with the expectation that your team will run it. Ongoing support is available, but it is not required to keep the system working.
