Stacked Marketer is a digital media company serving the global marketing industry. Founded in 2017 by Emanuel "Manu" Cinca, it has grown from a single flagship newsletter into a portfolio of publications—Stacked Marketer, Psychology of Marketing, and Tactics—reaching ~100,000 subscribers worldwide. The company also operates Stacked Marketer Pro, a premium platform with in-depth reports and a private community for marketers.

As the business grew, so did the operational demands. More newsletters and a larger subscriber base meant more advertisers, more campaigns, and more moving parts. What had once been a simple process for handling a single sponsorship slot gradually became a complex and time-consuming workflow.

From Simple Calendar to Complex Newsletter Sponsorship Management

In the early days, sponsorship management was straightforward.

When we started, we had one newsletter and one ad placement. A simple calendar was enough to keep track of everything.

With limited demand and only a single slot to manage, a basic scheduling tool was enough. As audience growth accelerated and sponsor interest increased, the number of placements and newsletter editions expanded. The once simple process began to strain.

The team moved from a basic calendar tool to spreadsheets. While spreadsheets helped manage dates, they didn't solve the broader operational challenges.

The spreadsheet wasn't bad for managing dates. The real challenge was everything around it.

Why Manual Newsletter Sponsorship Workflows Stopped Scaling

Managing newsletter sponsorships involves much more than booking slots. Every campaign required collecting creative assets, coordinating approvals, tracking deadlines, sending reminders, and preparing performance reports. With spreadsheets and email as the primary tools, each of these steps became a separate, manual effort.

Reminders to sponsors were probably one of the hardest parts. You constantly had to keep things in your head.

Over time, the process became fragmented across multiple tools. Scheduling lived in spreadsheets, communication in email threads, and reporting in separate analytics systems. As Stacked Marketer added more newsletters and more placements, it became clear that the existing approach would not scale.

Choosing Sponsy to Centralize Newsletter Ad Operations

The team began looking for a platform built specifically for managing newsletter sponsorships end-to-end. They needed a structured way to unify scheduling, communication, asset collection, reminders, and reporting in one place.

That search led them to Sponsy—a platform designed specifically for newsletter sponsorship operations. During the evaluation process, Manu was invited to share his challenges directly with the Sponsy team. Before the platform officially launched, Sponsy conducted in-depth interviews with newsletter operators—including Stacked Marketer—to better understand day-to-day workflows and pain points. That feedback helped shape key aspects of the product, including asset collection, automated reminders, reporting, and calendar management.

The decision to adopt Sponsy was less about replacing a single tool and more about creating a workflow that could scale reliably with future growth.

Replacing Spreadsheets with Automated Sponsorship Workflows

Implementing Sponsy meant moving active campaigns out of spreadsheets and fragmented systems into a dedicated sponsorship platform. Instead of switching constantly between calendars, email threads, and internal documents, the team gained one structured environment for managing the full sponsorship lifecycle.

It saves a lot of time. But even more than time, it saves mental energy.

One of the biggest improvements came from automation. Tasks that previously required manual follow-ups—chasing assets, checking deadlines, sending reminders—became reliable background processes.

You set it once, and you're done with it. That's extremely helpful.

Automated sponsor reminders in particular removed a major operational burden. What once depended on personal memory and constant checking was transformed into a consistent, predictable workflow.

Managing Multiple Newsletters from One Sponsorship Dashboard

As Stacked Marketer expanded to multiple newsletters, Sponsy provided a single source of truth for all sponsorship operations.

Everything is still broken down in one place. It feels like the one place to go to.

Whether a campaign runs in the flagship daily newsletter or in a specialised topic newsletter, the process is managed through the same central dashboard. Sponsors experience a consistent, professional workflow, while the internal team benefits from a centralized system rather than fragmented tools.

Automated Newsletter Sponsorship Reporting and Analytics

Another major improvement came from Sponsy's integrated reporting.

Before Sponsy, evaluating sponsorship performance required exporting data from multiple systems and manually consolidating it. With Sponsy, engagement metrics and revenue data are available together in one platform.

You don't have to export from a bunch of places, clean up data, and build pivot tables.

This visibility allows the team to understand fill rates, pricing effectiveness, and sponsor performance much more easily.

Having that data on demand helps us make decisions faster and be more efficient with our ad strategy.

Saving 15 Hours Per Week Managing Newsletter Sponsorships

The most concrete impact of Sponsy has been time savings. Reflecting on the difference, Manu estimates that the platform has removed a significant amount of repetitive work from the team's weekly routine.

Overall, I'd say around 10 to 15 hours per week is a fair estimate.

Those savings come from eliminating manual tasks such as asset collection, sponsor communication, performance reporting, internal coordination, and deadline reminders. More importantly, Sponsy has made it possible to add new placements without adding operational complexity.

Sponsy was something that enabled us to do more placements without as much time investment.

What might previously have required additional headcount can now be handled smoothly by the existing team.

Scaling Newsletter Ad Inventory Without Adding Headcount

As Stacked Marketer continues to grow its newsletter portfolio and advertising inventory, Sponsy provides the structure to support that expansion. Launching a new newsletter no longer means creating new spreadsheets or processes—it simply becomes another channel managed within the same system.

All of this being semi-automated definitely helps you scale compared to the alternatives.
