Data protection friendly fashion label

Hi!

With a group of friends with various backgrounds, we decided to launch a new fashion label for premium leisure wear. We're currently working on the first line of products and on a data protection first MVP:

• Only technically necessary cookies
• no 3rd party/marketing cookies
• whenever possible: based on european MarTech and data stored in Europe (privacy shield issue / German court recently ruled the exchange/storing of data on us servers as non compliant)

Current stack planned for the MVP (launch is planned for summer):

• Webshop & Landing pages: Squarespace (US, I know 🙈)
• Web tracking: Microanalytics.io for highlevel tracking, Hockeystack.com for customer journey tracking
• Newsletter & marketing automation: Sendinblue.com
• CDP: mautic.org (not planned to be used as marketing automation platform)
• Connection: integromat.com
• A/B Testing: Splitstack.co

What do you think of the planned stack? Any alternatives or additions you would recommend, considering the mentioned requirements?

Thank you for your inputs!
