Marketing Agency Envy Uses D-ID Avatar to Double Engagement and Personalize Outreach

A Case Study

Name: Envy

Industry: Tech Marketing, Revops

About Envy

Envy is a B2B tech marketing and RevOps agency established in 2014. by Billy Cina and Idan Carmeli are Managing Partners. The agency helps high-growth tech companies sharpen their go-to-market strategies and scale revenue operations through a unique blend of creative marketing and technical expertise.

With a core team of 15 employees and a network of freelancers, Envy operates across two key disciplines: digital marketing, including GTM and content strategy, paid media, and growth campaigns, and HubSpot operations, where the team is recognized as an Elite HubSpot Partner.

Envy works with international Post Round A and enterprise tech clients in sectors like cybersecurity, fintech, and medtech. Billy and Idan lead the agency with a product mindset, applying rigorous KPIs and a commitment to experimentation, constantly testing the very tools and tactics they bring to clients.

The Challenge

Like many fast-moving agencies, Envy is known for a robust content strategy and a “practice what you preach” approach—investing in its own marketing with the same rigor as its client projects. But producing video content at scale was always a logistical headache.

Traditional video production brought several challenges:

• Resource-Heavy Logistics: Filming days required booking videographers, organizing lighting and equipment, and coordinating team schedules—all for a single, high-pressure day packed with ideas. If a video didn’t work out, it was months before there was bandwidth to try again.
• High Cost: Studio sessions and professional shoots are expensive, especially for a boutique agency committed to frequent content creation.
• Slow Turnaround & Creative Bottlenecks: Even with an in-office mini studio, producing video content was time-consuming. Every shoot meant setting up equipment, re-recording multiple takes, and troubleshooting technical hiccups. The process made it difficult to respond quickly to trends or spontaneous ideas. As Billy put it, “It’s a pain, and we still do it, but we wanted more flexibility—to say things instantly.”
• Personalized Outreach at Scale: Sales and event follow-up increasingly requires personalized, video-driven communication. The old process couldn’t keep up: Idan Carmeli was spending a lot of time recording short videos for sales, and I became obsessed with Loom, but it just wasn’t scalable for how much we wanted to do.”

Envy needed a solution to scale up event follow-up and sales outreach and let the team focus on ideas, not production hassles.

Enter D-ID: The Birth of “Billy 2.0”

Always keen to experiment, Envy turned to D-ID to launch “Billy 2.0” – a digital twin made for their Managing Partner, Billy. After unresolved frustrations with other avatar providers, they found the process with D-ID refreshingly smooth: “We created Billy 2.0 and put her to work, just to see if it was really that easy. Turns out, it really is.”

How Envy Uses Avatars

Personalized Event Follow-Up

After hosting events, Envy used Billy 2.0 to reach out to attendees and no-shows, tailoring the script and delivery to each contact.

Newsletter Engagement

The March edition of Envy’s monthly newsletter featured a Billy 2.0 video greeting subscribers and summarizing the content.

Sales and Client Communication

Envy now incorporates avatars into sales outreach, saving hours of filming and editing.

The Results

• 50% Open Rate on the Billy 2.0 avatar email campaign, which is nearly double Envy’s average.
  
• 68% of recipients who opened the email read it in full, with another 30% skimming the content.
• 15 Direct Responses and 7 Meetings Booked so far, with more responses rolling in.
  
• March newsletter avatar edition: Average open rate jumped from 28% to 49% and Click-through rate more than doubled, from 2.6% to 5.9%

“The results blew me away.” Billy noted, “People are responding, booking meetings, and we get great feedback every time. People tell us, ‘We love what you’re doing’—that’s exactly what you want as a marketer.”

Why Do Digital Humans Work?

Cost and Flexibility: D-ID avatars allow Envy to produce videos at scale, without the cost or hassle of frequent filming days.

Personalization at Scale: Scripts are customized for every recipient, giving a personal touch to outreach. “Getting a CEO to record a video once is tough. With avatars, you get all the benefits of video without all the hassle.”

Authentic Approach: Envy made the content more approachable and memorable by using avatars transparently.

Best Practices & Tips From the Real Billy

• Don’t read from a teleprompter. Speak naturally, even if you waffle. You can always tell when someone’s reading, and it’s just not good.
• Don’t move your hands too much—I speak with my hands a lot, but it makes for some funny moments in the avatar.
• Add a ‘turn up the volume’ note to the video, because sometimes the subtitles don’t appear automatically, and engagement goes up when people can hear you!
• Keep it authentic. Don’t try to pretend your avatar is a human… People can tell, and then it becomes annoying and inauthentic. 

What’s Next for Billy 2.0

Envy plans to expand avatar usage on its website, creating personalized greetings for returning visitors. There are also plans to offer avatar-powered content for Envy’s clients and further integrate avatars into future newsletter editions.

Billy sums it up best:

“Marketing should be fun, and avatars make it easy to convey a message in a memorable way. Don’t take it too seriously—just enjoy it.”
