Our experience with Flowium was outstanding. From the beginning, the sales agent, strategist, and project manager were professional, friendly, and incredibly accommodating to our needs. They took the time to really understand our goals and patiently explained their recommendations in a way that was easy to act on. They provided a comprehensive audit that went beyond surface-level feedback and delivered deep insights into automation, segmentation, campaigns, industry standards, etc. Their in-depth knowledge turned our email audit project into a success. Since implementing some of their recommendations, we’ve already seen notable improvements in our click-through rates. If you're looking for strategic email guidance that delivers real results, this is the team to hire.

I operate a small real estate company and wasn't sure if Flowium could or would work for my business since I did not have a big online presence and am mostly "brick and mortar." When I reached out and began discussions with Flowium, I was blown away by the comprehensiveness of their recommendations; not only did it include a variety of suggestions outside of email marketing, but they provided me with guidance on how I could go about executing that plan, with or without Flowium. But based on the quality of their guidance, their evident expertise, and their level of service/personalization, I opted to work directly with Flowium. I am in that process now and couldn't be happier. While I went to them for marketing consultation, I am learning a lot about business just by watching them work! I happily and surely recommend working with this company. The more I learn about the organization, the more I love it.

My company worked with Flowium to migrate from Mailchimp to Klaviyo. The migration only lasted 2 weeks and Flowium handled everything flawlessly. As part of the migration they setup flows for our Welcome Series, Abandoned Cart, and Browse Abandonment. Every flow was detailed and used best practices so all my team had to do was go in and create the specified emails. Being a small business is difficult with so many tasks needing to be done everyday. Flowium was able to help take a load off of us so we could focus on other parts of our business. We look forward to working with them in the future.
