About Singulary ‑ Merge Customers

When your store has duplicate customers or email typos, order history splits, emails bounce, and LTV and marketing segments break. Singulary audits your whole customer list: it detects duplicate profiles by name, email, address and phone, scores each match by confidence, and flags invalid emails and incomplete addresses. Merge and fix them in bulk or side-by-side. Set up scheduled scans and instant checks for new signups. Includes Klaviyo and Shopify Flow integrations to keep your data in sync.

Very useful and easy-to-use app! Exactly what we need, and the support service is super responsive!
— RainbowMeal
This is an app that is quietly helping us make much better business decisions! We are hiring someone to do some analytics work for us on measuring new customer acquisition and retention rate. If someone had asked me how many duplicate customers we had on our file i would guessed maybe 500. I was off by a factor of 10! Getting an accurate count of your customers - new and repeat is CRITICAL for u...

Great app as I have literally 1000's of these issues as I am a boutique. they fixed issues I did not even know I needed
— Petticoat Lane
If you have a large customer base which over the years has become duplicated with customers changing emails, misspelling emails or capitalizing names Singulary fixes these in the blink of an eye and then continues to monitor your base to see everything remains synced. An excellent app which has saved me massive time and is worth every cent that is worth. Can't recommend highly enough
— Everything Fabric
Very simple to use and effective app. We stugguled with duplicate profiles from a very long time and this helped us in merging all the profiles with just one click.

Hidden Gem. Love this.
— Saree Ghor Charlotte
We've just begun working with this app, and all suggestions have been implemented or clarified immediately! I love how responsive and helpful the team has been and look forward to seeing how much more this app can possibly improve. It's saving me a ton of time and resources!
— Lone Star Adhesive
Best app for de-duping your store customers. Managed to remove over 1k duplicated contacts in just 1 day, a process which would have taken days if not weeks using spreadsheet and Shopify's inbuilt merge tool. Requested additional functionality to de-dupe multiple contacts at same domain and development team had added functionality in less than an hour. Clean interface, powerful and incredible cus...

This app is getter better and better each day! The developer really cares about constantly improving and making a superior product to any other tool like this on the app store. I can't be happier with how responsive they have been and how the tool has evolved and changed to meet our needs. I'll be looking specifically for them when choosing future apps as well - they seem to be on a path to major...

We are friends of the developer and helped beta test the app. That said, it's genuinely useful! We had duplicate customers we didn't know about, and the app found and helped us merge several of them quickly. The matching is solid and the merge process is simple. Definitely worth trying if you have messy customer data.
— dlirioshop
A very helpful app! We had duplicate records piling up and didn't even realised how much it was affecting our reporting. This app found matches we would have never caught manually, and the merge process was seamless. Feels great to have cleaner database now without having spent hours on it.
