Mariokerkstra is a company that provides online marketing services to help businesses grow their sales through SEO management, newsletters and CRM systems. The company was founded in 2014 by Mariëlle van Woudenberg, who has over 10 years of experience working as an online marketer for different companies.

The idea behind Mariokerkstra arose from her own frustrations with trying to do everything on her own. She knew how hard it was to find all the information she needed about SEO management, social media marketing or newsletter campaigns – so she created a solution for herself first before launching it into the world!
