Hi, I’m Idris and I’m the founder of Retentiononly.
Doing email marketing for the past 6 years and being invested over 32k EUR to receive coaching from the best agencies and freelancers in the German speaking market has made me learn their collected best practices they have accumulated over the years.
I never understood why agencies would work with more clients that they could actually handle and get results for, so I’m taking pride in only working with a hand-full of brands that I can take care of just as you as the brand owner would do yourself if you would have my expertise.
But importantly I care about you and your business.
