How Sendoso reclaimed pipeline with Amplemarket: 3.2x replies and under 3% bounces

Sendoso is the leading platform for B2B gifting, helping companies create more meaningful connections through intentional, human-first outreach. While the team embraces AI to scale outbound, maintaining a personal touch is non-negotiable.

To support their BDR org, Sendoso partnered with Amplemarket, using the platform to power signal-based outreach, streamline workflows, and simplify rep onboarding.

Sendoso automated routine tasks while maintaining their signature human-first approach with Amplemarket’s Duo Copilot, a set of AI agents that work alongside sales reps to proactively find exclusive buying signals, research prospects, and generate personalized multichannel sequences.

At the same time, Sendoso also runs scaled, creative outbound plays through Clay, leveraging both platforms strategically.

This is the story of how Sendoso leaned on Amplemarket to optimize their BDR productivity, what happened when they tested a different vendor for their BDR motion, and how they returned to Amplemarket stronger than ever.

Before Amplemarket, Sendoso’s BDR motion was fragmented across multiple platforms. Reps juggled enrichment, engagement, and signal tools separately, slowing them down and diluting performance.

Without AI agents to coordinate these workflows, reps spent more time managing tools than engaging prospects.

The Head of Sender Relations Katie Penner gave us some insights.

"Our tech stack is robust, which is great, but can be overwhelming for new BDRs."

Amplemarket brought structure and simplicity to the BDR workflow: one platform with built-in signal discovery, pre-written messaging, and multichannel outreach tools. For Katie’s team, it meant faster ramp time and less guesswork.

“With Amplemarket, our reps had everything in one place. It gave them a clear, intent-driven path to pipeline.”

Despite strong results with Amplemarket, the Sendoso team briefly trialed another platform for the BDRs in an effort to consolidate vendor costs.

On paper, it offered similar capabilities. In practice, it derailed performance.

“It was like flipping a switch. One day we had healthy pipeline. The next, we were going straight to spam.”

The replacement platform introduced:

• Poor deliverability and weak enrichment
• Bad data and inaccurate phone numbers
• Clunky UX and slow support
• Frustrated reps and declining results

“We lost pipeline, plain and simple. I wasn’t going to waste time trying to fix broken campaigns.”

The team saw immediate recovery after re-enabling Amplemarket for the BDR org.

“As soon as we got back on Amplemarket, our inbox placement and reply rates rebounded. It was night and day.”

With Amplemarket's AI sales agents, reps could personalize at scale without sacrificing speed. Signals like job changes, buyer intent, and social engagement powered relevant, timely outreach, perfect for Sendoso’s relationship-first strategy.

“We could plug in gifting language, tweak the 
tone to match our voice, and hit send. It was plug-and-play personalization.”

The AI agents worked autonomously to research prospects, craft personalized messages, and manage follow-up sequences, freeing reps to focus on relationship building.

By combining Amplemarket for rep-led outreach with Clay for scaled outbound, Sendoso enjoys the best of both worlds: a high-touch BDR motion and highly personalized automation at scale.

Since returning to Amplemarket, Sendoso’s BDR team has rebuilt a high-performing, scalable outbound engine:

smart, and it helps us build real pipeline.”

Implementing AI agents transformed how our team operates. What used to take hours of manual work now happens automatically while maintaining our personal touch.

With signals like re-engaging closed-lost leads and custom signal filters, the Amplemarket product team keeps delivering exactly what Sendoso needs.

“Every new feature has hit the mark, they’re shipping fast and listening closely.”

Sendoso’s success comes from blending AI with emotional intelligence. With Amplemarket driving the BDR team and Clay powering scaled personalization, they’ve built a modern outbound engine that respects both efficiency 
and connection.

“We use AI to make space for what matters: meaningful, human engagement. That’s what 
sets us apart.”
