The Company

Better-fit inquiries for event venues.

PartySlate is a hospitality technology platform that connects event venues with better-fit, higher-revenue event inquiries. The platform helps venue operators attract the right events, reduce low-fit leads, and increase revenue per booking across their event spaces.
The Challenge

A tight, relationship-driven market.

PartySlate needed to build pipeline with hospitality and event venue decision-makers, a tight, relationship-driven market where cold outreach rarely breaks through on its own. The goal: generate qualified meetings with venue operators who could benefit from attracting better-fit, higher-revenue event inquiries.
The Approach

Layered, multi-touch demand generation.

FullFunnel deployed a coordinated program across three channels with 12 total touch points per prospect. Each layer served a distinct purpose; together they warmed, engaged, and converted a difficult-to-reach audience.
Layer 1

Cold outbound email

Build the foundation with persistent, personalized sequences.

3 parallel campaigns via Instantly.ai with distinct sender personas
4-step sequences on a 4-day cadence across all campaigns
Value-driven messaging around higher-quality inquiries and revenue per booking
Dynamic personalization by first name, company name, and custom body copy
Layer 2

Teleprospecting

Add a human touch coordinated with email timing.

Active teleprospecting coordinated with email sequences
Calls timed to land while prospects were actively receiving and opening emails
Increased reply and meeting conversion across the full sequence
Layer 3

Paid inbound (Meta Ads)

Create top-of-mind awareness that makes outbound warmer.

Meta Ads + inbound funnel introduced at the ~6-week mark
Created channel reinforcement across touchpoints
Prospects who saw an ad were warmer when the email arrived, and vice versa
Layer 4

Infrastructure & deliverability

Ensure every email lands in the inbox, not spam.

5 dedicated sending domains with 100% inbox health maintained
Up to 70 warmup emails deployed per inbox prior to launch
Security gateways mapped: Microsoft, Google, Proofpoint, Mimecast, Cisco
The Inflection Point

Open rates built a foundation. Layering paid on top turned it into a pipeline engine.

Outbound email built a real foundation: 67% open rates sustained over 2.5 months, well above industry benchmarks. But open rates don't close deals — the outbound motion on its own produced modest conversion. The breakthrough came when FullFunnel layered paid inbound on top of the active outbound program, creating channel reinforcement that transformed pipeline generation overnight.
Phase 1 · Outbound only (Weeks 1–6)
Cold email + teleprospecting across 3 parallel campaigns. Open rates were immediately strong, but open-to-reply-to-meeting conversion was modest without complementary channels.

Meetings booked
Phase 2 · Outbound + paid inbound (Weeks 6–10)
Meta Ads layered on top of active outbound. Prospects who saw an ad were warmer when the email arrived; those who got the email were primed when they saw the ad. In the first two weeks:
27
Opportunities (21 inbound + 6 outbound)
Outbound alone produced real results. Outbound supported by paid produced a 13.5x increase in pipeline opportunities in one-fifth of the time. The channels don't just add up; they multiply.

Why It Works · FullFunnel's Role

Every touch point compounds. So does the performance.

FullFunnel builds and runs full-funnel revenue programs that combine outbound sequencing, teleprospecting, paid media, and marketing operations into a single coordinated motion. This engagement is a proof point: outbound alone built a foundation, but layering paid on top of an active outbound motion is what turned it into a pipeline engine. The relationship compounds, and so does the performance.

Client Perspective
As a RevOps team of one, I'm always spread thin across many different initiatives, so having FullFunnel as a partner has been a game-changer. They're a sounding board, a subject matter expert on all things GTM, and an extra set of hands (or two, or three) that can actually execute on the work. They've helped us build a full-scale campaign to generate net-new leads from the ground up. We started with the outbound engine, but adding inbound to complement and round it out is where we really started seeing results. I've worked with other agencies in the past, and the FullFunnel team has blown them out of the water: they get things done with very little direction or back-and-forth, and proactively bring me new ideas to test.
