After working with 3 or 4 different agencies we started working with George and his team and we noticed the difference, they focus on growing your business, very fast and good comunication and we have more than 20% revenue from email marketing in a business of more than $1M. I highly recommend this agency, more than an agency now is a partnership :)

⭐️⭐️⭐️⭐️⭐️ 5/5 — Exceptional Partner for Email, SMS, and Retention Marketing Working with Yocto—specifically George and his team—has been nothing short of phenomenal. From the very beginning, it was clear that George genuinely cares about his clients’ success. We’ve been collaborating for a few months now, and the level of dedication, creativity, and strategic thinking he brings to the table is truly second to none. The ideas George proposes are consistently innovative and impactful. Many of the strategies he’s implemented have gone beyond the standard scope of work, yet he and the team took them on proactively because they believed they would drive better results—and they were absolutely right. Our engagement and revenue have shown measurable improvement every single day. What stands out most is their reliability and professionalism. They come prepared to every weekly meeting, they’re prompt, and they always keep our best interests in mind. Month after month, we see clear upticks in performance, and it’s hard to ask for more from a marketing partner. I highly recommend Yocto for anyone looking to elevate their email, SMS, and retention marketing. They’ve done an outstanding job for us, and we look forward to working with them for a very long time. Jay Hofstatter DailySale, Inc.
