Stimulate takes a very data-driven and analytical approach and the results speak for themselves. Hire this team: Randy and Stimulate are the only ones you need.
David Brown
CEO + Co-Founder, FireRoad
I’ve been working with Stimulate for almost three years now, and they do an outstanding job with email & SMS marketing including campaigns and journeys. They really immerse themselves in the brands they work with. I highly recommend them!
Shimshy
Marketing Manager, Editors Pick
Working with Stimulate has made my life so easy. The team writes and designs on-brand emails, puts together the whole content calendar, manages reporting, and so much more, all with very little feedback needed. And as a result, Stimulate has not only freed up my time but we’ve seen our email & sms channels grow exponentially.
Kerry
Founder & Aesthetician, StackedSkincare
Stimulate has increased our email and SMS revenue by many multiples in under 12 months of working together. And they do everything - copy, design, strategy, deployment, reporting. It has been one of the best agency experiences I've had. I can not recommend more highly.
Craig
CEO & Founder, Speks
There are a million agencies and freelancers trying to sell you email marketing. It's refreshing to work with Stimulate because in a sea of 'experts', they actually are one. Within two months of working with Stimulate, we achieved the highest total revenue from flows in our brand's five-year history, and this was not an easy lift as email revenue was already high. I wish I found them three years ago. I highly recommend working with them.
Josh Walker
Co-Founder & CMO, 1620 Workwear
Stimulate’s commitment to and understanding of analytics is a welcome change from what we have experienced with other email marketers. The team has a fantastic understanding of campaign optimization and has the platform skills to execute effectively. For anyone looking for help with managing email communication I would highly recommend Stimulate!
Eric Steckling
Founder, Brio Product Group
What impressed me most about Stimulate is their ability to truly understand our brand and customer base. They didn’t just apply generic strategies; instead, they took the time to tailor their approach specifically to our needs, which made all the difference in our results. Their use of data-driven insights and predictive analytics to drive personalized campaigns was particularly unique and effective. In short, Stimulate brings a combination of creativity, technical expertise, and a true understanding of retention that sets them apart from others in the industry.
