Hi,
I just want to share with you the new app I’ve built. It’s called Singulary, and it allows you to easily find and merge duplicate customers. When analyzing your customer’s database it also checks for misspelled emails (for example @gmal.com) and name formatting issues (all caps, extra spaces, etc.).
It’s been already 4 months since it was released, and we already merged +80,000 customers. I hope you find it useful!
