Zintex increased repeat and referral sales by more than 90% year over year by implementing a long-term, automated post-install follow-up and customer engagement program with gFour.

The Challenge: Scaling Consistent Post-Install Follow-Up

Zintex serves 30+ markets and is known for delivering high-quality bath, shower, and walk-in tub projects. As the business scaled, the team wanted a more reliable and scalable way to:

Eric put it plainly:

“If somebody tries to do it themselves and they don’t have a really good, clean process and procedure… it’s just not going to work. Things get forgotten.”

Zintex wasn’t looking to add another manual task to the marketing team’s plate. They needed a system — automated, consistent, and customer-first.

The Solution: A Done-For-You Post-Install and Customer Engagement Program

By partnering with gFour, Zintex implemented a post-installation and long-term nurture program that runs behind the scenes, while still feeling personal to the customer.

1. Memorable post-install gifting

Customers receive a thank-you package after installation — a touchpoint designed to leave a lasting impression.

“It separates us from our competitors that aren’t going to provide the customer with some type of a gift package after their installation is done…

They’re going to remember that you sent them something that made them feel good about doing business with you.”

These moments often spark direct replies from customers, sharing excitement about the project or appreciation for the gesture.

2. Staying top of mind with automated follow-up

gFour’s email follow-up keeps Zintex connected with customers well beyond the installation date.

“We get so many emails back from customers that say, ‘Thank you so much for the cookies. My grandkids really enjoyed them. We love our new shower.’”

These ongoing touchpoints reinforce goodwill and naturally open the door for referrals.

3. Review collection and CRM-powered re-engagement

In his testimonial, Eric also highlighted several gFour capabilities Zintex uses to extend the value of each customer interaction, including:

“They also have… review generation, the ability to integrate with your CRM, remarket, rehash opportunities, reset opportunities, and hopefully get you back into some of those homes to generate more sales.”

The Results: 90%+ Growth and Higher Close Rates

📈 Over 90% year-over-year growth

Repeat and referral business increased by more than 90% in Zintex’s most recent year.

🔥 Elite close rates

“These are leads that are going to close at a higher amount.”

⏳ Compounding growth after a 6–9 month runway

Eric is clear that relationship marketing isn’t a switch you flip — it’s a long-term brand asset.

“You have to be able to spend at least six to nine months to see what it’s truly capable of.”

With consistency and time, Zintex began to see repeat and referral performance accelerate year over year.

Why Zintex Chooses gFour Over Doing It Internally

When asked why he recommends gFour instead of managing relationship marketing in-house, Eric pointed to focus and execution:

“Time is money and money is time.
If somebody tries to do it themselves… it’s just not going to work.
It’s easy to forget about asking for reviews or referrals.

This is something that’s always going on behind the scenes that we don’t have to worry about.”

For Zintex, gFour delivers:

Final Takeaway

Zintex’s results underscore the impact of pairing strong core marketing efforts with a consistent relationship-marketing system.

By putting a structured, automated program behind their customer base, Zintex has been able to strengthen loyalty, increase reviews, and drive meaningful year-over-year growth in repeat and referral business — all while supporting the broader marketing strategy already in place.
