Cold Email Case Study

How One Team Hit 270 Replies in 30 Days with Cold Email Outreach

Cold email is one of the fastest ways to book meetings and grow pipeline, but only if your emails actually land in the inbox. For most teams, the biggest challenge is cold email deliverability. You can have the best list and the best copy, but if your messages are flagged as spam, results flatline.

That is exactly what happened to Tim’s team. After trying nearly every platform like SendGrid, Growbots, Vidyard, and Mailchimp, they finally gave up on cold email three years ago. “Deliverability sucks,” was their conclusion.

Then they tried SuperSend. The difference was immediate.

270 Replies in 30 Days: Real Campaign Results

In their very first campaign, the numbers looked like this:

• 270 replies in 30 days
• Just 18 “not interested” responses
• Only 2 opt-outs

The rest were real conversations with prospects.

Even more impressive, they are averaging 5–10% reply rates daily. One day, they sent just 600 emails and received 35 positive replies, which is a 5% response rate in 24 hours.

What Makes a High-Performing Cold Email Strategy

Most cold outreach fails because of poor setup. SuperSend handles the technical side so every message has the best chance of hitting the inbox. Here is what made the difference for Tim’s team:

• Infrastructure done right: Domains purchased, inboxes created, and warming handled by SuperSend.
• Deliverability-first email strategy: No links, no flashy signatures, just simple plain-text emails to build trust and improve inbox placement.
• Smart inbox management: Using SuperSend’s Replies Inbox, Tim can sort through new replies in seconds without missing leads.

“All we sent was like 600 emails, and we got 35 interested replies just yesterday. That’s a 5% return in one day, and honestly, that’s a low day. We’re averaging closer to 10% reply rates.”

Cold Email Deliverability: Why It Matters

If you are sending campaigns without monitoring deliverability, you are burning your list. Emails that land in spam never create pipeline.

SuperSend’s done-for-you setup ensures:

• Every inbox is warmed properly
• Your sending reputation stays clean
• Campaigns scale safely without hitting spam filters

That is why Tim’s team was able to restart cold email after years of frustration and immediately see results.

Key Takeaway

Cold email is not dead. It is just broken when deliverability is ignored. By fixing the infrastructure and focusing on clean, simple messaging, Tim’s team turned a shut-down channel into one of their best-performing revenue drivers.

If your cold email reply rates are flat, it is not your pitch. It is your deliverability.
