How Sendoso reclaimed pipeline with Amplemarket to score 3.2x reply rates & <3% bounces

Sendoso’s signal-led pipeline success at a glance:

• <3% bounce rate on emails sent via Amplemarket
• 78%+ open rate on Duo-generated leads
• 3.2x reply rate on Duo leads vs. all leads

Background

Sendoso is the leading platform for B2B gifting, helping companies create more meaningful connections through intentional, human-first outreach. While their team embraces AI to scale outbound efforts, maintaining that 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. At the same time, Sendoso 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.

The challenge: too many tools, not enough precision

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.

“Our tech stack is robust — which can be great, but 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.”

The setback: a switch that cost 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 solution: reunited with Amplemarket & Duo Copilot

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 Duo Copilot, reps could personalize at scale without sacrificing speed. Signals like job changes, buyer intent, and LinkedIn 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.”

Using Amplemarket for rep-led outreach and Clay for scaled outbound gave Sendoso the best of both worlds: a high-touch BDR motion and highly personalized automation across broader audiences.

The results: happier reps, healthier domains, more pipeline

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

• <3% bounce rate on emails sent through Amplemarket
• 78%+ open rate on Duo-generated leads
• 3.2x more replies on Duo leads vs. all Amplemarket leads
• 25% reply rate just from competitor engagement signal

“Our BDRs love the platform. It’s fast, it’s smart, and it helps us build real pipeline.”

And with features like Re-Engage Closed-Lost Leads and custom signal filters, the Amplemarket product team continues to deliver exactly what Sendoso needs.

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

Conclusion: Tech that scales without losing the human touch

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.”

Amplemarket gives Katie’s team the confidence and clarity to act on buying signals, personalize outreach, and build pipeline that lasts.
