Success Metrics

99%

Email deliverability with ListKit's infrastructure

50-60%

Improvement over standard email delivery methods

Overview

ElmStreet offers a portfolio of residential real estate SaaS products designed to help real estate professionals with marketing, brand presence, lead generation, and lead qualification. They recently launched a new website solution with fully integrated live listing data, allowing real estate agents to display MLS listings on their personal websites similar to how Zillow displays properties.

After discovering ListKit through industry recommendations, ElmStreet decided to leverage cold email to test market reception for their new website product. Though they had some previous cold email experience, they hadn't used it in recent years and needed a solution that could provide both high deliverability and a streamlined setup process.

ListKit's done-for-you cold email setup allowed ElmStreet to focus on their messaging and offer while the technical infrastructure was handled for them. This partnership has enabled them to gather valuable market feedback, book demos, and close deals while continuously optimizing their approach.

Key Highlights from the Interview

Market Testing

"Cold email is by far the cheapest and also the quickest feedback from our experience to test new offers."

Marino

00:05:55-00:06:10

Valuable Feedback

"Even the negative responses are pretty informative because it helps you figure out what you want to change up and what's not making sense in how you're framing it."

Marino

08:33-08:59

Deliverability Advantage

"There's no other way to get high inbox hit rates without a system like this... there's just no point in doing large scale campaigns where you get like 50 or 60% delivery."

Marino

10:21-10:45

Actionable Insights

"People are telling you, 'hey, Andre, your brownies suck,' right? So, you might have to go back and change that recipe... But the overall feedback is, 'hey, I'm not really in the mood for brownies right now, but they smell really good.' Okay, we're doing something right."

Marino

13:06-13:23

Higher Intent

"It's higher intent if someone's responding to an email from their business email... you're targeting people with business emails, so they run a business and it's verified, triple verified through our system."

Marino

15:16-15:35
