Question 1

How does MergeGuard detect duplicate customers?

Accepted Answer

We analyze email addresses, phone numbers, names, addresses, and order patterns to identify duplicate profiles with high accuracy.

What data points are used for matching?

Accepted Answer

Email (including variations), phone (normalized), name similarity, address matching, and behavioral patterns like IP and order timing.

Question 3

Can I review merges before applying them?

Accepted Answer

Absolutely. Every merge suggestion is grouped by confidence level. You review, approve, or skip each one before anything is merged.

Question 4

What happens to order history after merging?

Accepted Answer

All orders from merged profiles are consolidated under the surviving customer record. Nothing is lost.

Question 5

Are tags, notes, and metadata preserved?

Yes. Tags are combined, notes are concatenated with timestamps, and all metadata is preserved during the merge.

Question 6

Can I exclude certain customers from merging?

Accepted Answer

Yes. You can skip individual matches or add customers to an exclusion list.

Question 7

Can merged customers be restored?

Accepted Answer

Shopify's native merge is permanent, but we maintain merge logs so you can see what was combined.
