Applause from our customers

Thanks to Mariko I was able to quit my salaried job

⭐️ ⭐️ ⭐️ ⭐️ ⭐️

Started with a Newsletter course and then went through all content coach programs. So stay that I did. I can safely say: if I hadn't followed this, I wouldn't have been able to quit my job as an employee. I now work full time on Jewels with Flair and I really enjoy working on my newsletter. A big difference from the beginning, when I thought every time... what should I put in my Mail with Flair? Thank you Mariko!

No quick, smooth talk but structure, peace and confidence

⭐️ ⭐️ ⭐️ ⭐️ ⭐️

I experience the collaboration with Mariko from Sell your stuff online as very pleasant. No fast, smooth talk, but structure, peace and trust. Also an occasional pep talk. She first tries to get a good idea of ​​what I feel comfortable with and then she bases her ideas on that. She took me step by step through the development. The end result is a webshop that suits me, feels good and works well. All this means that I will definitely recommend SYSO.

I wanted that too!

⭐️ ⭐️ ⭐️ ⭐️ ⭐️

I missed the right look and feel for my webshop, it had grown out of the homemade jacket. I've been following Sell your stuff for a while and saw the most beautiful branding projects from others. I wanted that too! And it immediately felt good with Mariko, she is a real professional and knew how to connect well with what I had in mind.
