What working with us did for our clients
Danny | Gitaar Barbaar
Finally getting maximum value from our existing traffic! We’ve been working together for about a year now and we’re extremely satisfied. While we already had a strong website and solid marketing in place, we noticed that our existing traffic wasn’t being used to its full potential. That’s exactly where these email flows made a huge difference. They set up multiple one-time flows for us that are still running today and continue to generate serious conversions every month from smarter cart recovery to better follow-ups and stronger content that truly supports our branding. What makes the collaboration even stronger is the speed and quality of their support. Questions and changes are handled quickly, and because they have designers in-house, everything is instantly taken to a much higher level than if you try to do it yourself. The result: more focus for us, time saved, and clearly better performance. They truly know what they’re doing, and you feel that in everything. Highly recommended."
Jordy G | Founder Pet Industry
"Excellent for me! I don’t even remember how long we’ve been working together, but the ROI was huge from the very first month! They also helped me prepare for BFCM it was my first time, so I had no experience at all. Thank you! And whenever something urgent comes up, they even launch emergency campaigns. Truly the best email marketing company I’ve found so far."
Nino | Wet van Rijkdom
"From Idea to Execution. These Guys Nail It Working with Simple Growth has been amazing for us. They’re a small boutique team, but don’t let that fool you they seriously know their stuff. From brainstorming ideas to bringing them to life, every step felt intentional and professional. Communication was always super clear, and the return on our investment? Way higher than expected. Highly recommend them."
Willem | Wellshine
"Third time’s the charm. This is our third agency for email marketing and CRO. With the first two, we left immediately after the fixed contract period because of the lack of results. With SGL, however, we’ve now been working together for more than six months!"
Aaron | Dallions
"35% Revenue Increase. We grew from online platforms to Shopify, but when we started, we had little knowledge of how to build an effective email system. SGL not only helped us strategically set up our flows, but also made sure our team had less on their plate. Today, more than 35% of our revenue comes from email, and we’re extremely happy with both the results and the support!"
Dustin | Wellshave
"Very satisfied. We’ve been working together for almost a year now, and the communication has always been pleasant and professional. The results speak for themselves, and we’re seeing great growth. We would definitely recommend them to other webshops."
Roberto | Phoenix Metaal
"Virgil helped us set up an automated email system to reach new potential customers, both locally and internationally. After several months of running the system, we can confidently say we’re very satisfied with the investment. Communication was always smooth, and there was great attention to our needs throughout the entire process. Keep up the great work!"
