B2B SaaS · Series B Acquired Under NDA

From 1.2% to 5.8% reply rate in 60 days

A mid-market sales team running cold outbound through generic templates. They switched to the Cold Email system, casualized and signal-driven. Reply rates 5x’d, meeting bookings tripled, and the company was acquired four months after deployment.

The Challenge

A sales team buried in templates and getting ignored.

The client’s outbound was running on a popular sequencing tool with stock templates and basic mail-merge. Reply rates sat around 1.2% across 12,000 sends per quarter. Their VP of Sales described it as “throwing emails at a wall and watching them slide off.”

The deeper issue was deliverability and detection. Inbox providers were flagging their templated language as automated. Even prospects who would have opened their door to a real person were never seeing the message. Internal SDRs were burning out trying to write personalization for thousands of accounts manually.

They didn’t need more volume. They needed messages that read like a human, scaled to a thousand a week.

The Approach

A casualized outbound engine, live on their stack in 9 days.

The Cold Email system did three things differently:

Before vs. After

The same prospects. Two very different inboxes.

These are anonymized examples of messages the same SDR sent to similar accounts before and after we deployed the new engine. The reply column tells the story. (Names, company details, and links are masked. Real templates shared on request under NDA.)

Before

1.2% reply rate

Templated mail-merge. Generic openers, fake personalization, no real signal.

Hi Sarah,

Congrats on the Series A. The piece in <publication> about how you’re scaling SDR ops was a great read.

Quick one: now that you’re ramping headcount, are reps still spending more time researching prospects than actually selling? That’s the bottleneck I keep seeing at this stage.

Worth comparing notes if so.

Hey Marcus,

Saw you’re hiring 14 SDRs into Q3. Curious whether you’ve thought about how to keep your existing team’s playbook from getting diluted as you bring on new reps.

We’ve helped a few similar teams keep tribal knowledge in one place so the new hires don’t reinvent it. Worth a quick chat?

Hey Eliza,

Minor thing, but: noticed the favicon on <website> is still your pre-rebrand mark. Probably nothing, but figured I’d flag it.

Separately: I read your post on the deliverability project. We hit the exact same warm-up wall last spring at a different client. Different topic but happy to share what we did if useful.

Higher reply rate

Same SDR. Same target accounts. Same daily send volume. The only difference: messages went out through the new engine instead of the old templates. Reply rate climbed from 1.2% to 5.8% within 60 days and held there.

Examples are anonymized and approximated. Real templates shared on request under NDA.

The Results

5x reply rate, 3x meetings, acquired in four months.

Within 30 days, reply rates climbed to 4.1%. By day 60, they hit 5.8% and held there. Meeting bookings tripled in the same window. The casualization layer was so effective that a prospect from a Fortune 500 customer wrote back asking for the SDR’s LinkedIn so he could connect; he had assumed the message was personally written.

The company was acquired four months after the system went live. The acquirer cited the outbound engine as a material asset in due diligence. The parent company still runs it today.

“We tried two other tools before Orbit. Neither got our outbound past template-detection filters. With Orbit the system was live in days and the messages actually sounded like us. By the time we sold the company, it was generating more than half our pipeline.”
