Agency New-Business Follow-Up Cadences: What the Data Says Works

Why Most Agency Outbound Cadences Underperform

Per SparkToro's 2025 survey, 59% of agencies have tried outbound sales as a new-business strategy. Only 9% call the results very effective, and a third say it wasn't effective at all. That's a striking gap between adoption and success, and it's worth being specific about what it does and doesn't mean. It doesn't mean outbound doesn't work for agencies. It means most agency outbound, as actually run, isn't producing results worth the effort, which points at execution rather than the channel itself.

The Reply-Rate Reality Behind a Single-Channel Cadence

Cold email specifically has gotten harder, not easier. Per Martal Group's 2025 data (via shno.co), agency cold-email outreach in 2024 ran a 27.7% open rate and a 5.1% reply rate, down from roughly 7% the year before. A single-channel, email-only cadence is fighting a declining number, and a cadence that stops the moment the first email sequence goes quiet is walking away from prospects who might have responded to a different channel or a later touch entirely.

The Pattern That Kills Cadences Before They Finish

There's a well-documented reason agency BD cadences tend to die mid-sequence rather than run their course. Da Costa Coaching describes it plainly: "the day-to-day grind of maintaining client relationships and pushing out campaign after campaign leaves little to no room for internal marketing initiatives," a framing corroborated independently by both Act-On and Canned Marketing. Agencies are good at running other people's campaigns and bad at running their own, and a BD cadence is exactly the kind of internal initiative that gets deprioritized the moment client delivery gets busy again.

That pattern lines up with the staffing data directly: 70% of agencies have no full-time salesperson and 79% have no one dedicated to their own marketing, per SparkToro. There usually isn't a person whose only job is to keep the cadence running when everyone else gets pulled onto billable work.

What a Cadence That Survives the Busy Season Looks Like

Two things separate a cadence that finishes from one that quietly dies. First, it runs across more than one channel, so a quiet inbox doesn't end the whole sequence, layering scheduled touches rather than relying on a single format. Second, it runs on a schedule that doesn't depend on someone remembering to send the next touch when client work spikes, which is precisely when a founder-run cadence is most likely to stall. If a cadence includes SMS as one of those channels, it also needs to run on documented consent, covered fully in the companion TCPA guide for agency outreach.

A Practical Checklist for a Cadence That Actually Finishes

1. Don't rely on a single channel. If email is your only touch, a declining 5.1% reply rate (per Martal Group) is the ceiling you're working against.
2. Build the cadence to run on a schedule, not on someone's memory during a slow week.
3. Expect it to be tested during your busiest client periods. That's exactly when the cobbler's-children pattern kicks in, and exactly when a scheduled cadence matters most.
4. Track how far prospects actually get through the sequence before going quiet, not just the final reply rate, so you know where it's breaking down.
5. If you add SMS to the mix, document consent per contact. The rule applies to agency-to-agency outreach the same as anywhere else.
