Stop Email List Decay. Replace Lost Subscribers. Find New Leads. Clean Your List.  Automatically.

Built for Event Organizers & Training Providers

Break-even is hard.
Don’t let empty seats eat your margin.

The economics of physical events are unforgiving. You have massive fixed costs—venue, catering, speakers—that must be paid regardless of attendance. If an invitation to a previous attendee bounces, that seat remains empty.

Fill Every Seat – Free Trial

The Challenge

The profit is in the last 20%

You aren’t just losing a ticket sale; you are carrying the cost of an empty chair. When a professional leaves a role, your invite to them hits a dead end.

The Reality: The need for training doesn’t disappear—it transfers to the person taking over. The “I have moved on” auto-reply is the fastest way to find the person who now holds the budget.

The Solution

Forward the Invite to the Right Person

We ensure your invitation reaches a warm lead instead of a dead inbox.

Identify: We spot when a past attendee has left.

Redirect: We extract the successor’s email so you can say: “We saw [Name] left, and thought you might want to take their place.”

Key Benefits

Corporate Continuity

Big clients often send multiple delegates. If a company usually sends 5 people, but 2 have left, you risk losing that revenue. We help you identify the new hires immediately so you can retain the full corporate booking.

Maximize Seat Utilization

Empty seats don’t buy coffee, lunch, or upgrades. They are sunk costs. By keeping your list fresh, you ensure every marketing email has the potential to convert into a paid ticket.

Secure Revenue Earlier

Last-minute sales are stressful and expensive to acquire. Reaching the right decision-maker early in the cycle helps you fill the course faster and secure your cash flow long before the event starts.

Every empty seat is lost revenue

Don’t let outdated data hurt your event’s profitability. Ensure your invites reach the people who need your training.
