Glow creates loyalty member records when Shopify or a Glow customer-facing surface gives Glow a customer it can identify. This is expected behavior: Glow needs a customer email, phone number, or Shopify customer profile so points, rewards, referrals, and loyalty activity can stay attached to the right shopper.
This does not always mean Glow created a Shopify login account or password for the shopper. In many cases, Glow is creating or updating a Glow loyalty member from an existing Shopify customer profile, an order, the loyalty widget, checkout, or a customer account page.
Why this happens
Glow may create a loyalty member when:
Shopify sends Glow a customer creation event.
A Shopify order can be matched to a customer by Shopify customer ID, email, or phone.
A signed-in customer opens the loyalty widget or a Glow customer account extension.
Checkout needs to show loyalty information for a known customer.
A member is added manually, imported, or created through an approved workflow.
Glow uses that member record to track points, referral links, reward redemptions, VIP tier information, and loyalty emails.
Check your Shopify customer account settings
In Shopify, go to Settings > Customer accounts.
Review whether sign-in links and customer account features are enabled for your store. Shopify controls the customer account experience, sign-in methods, customer profile behavior, and account URLs.
If shoppers are creating accounts through Shopify, Glow can pick up those Shopify customer profiles so your loyalty program can recognize them.
Understand what counts toward your Glow member limit
Glow counts active members, not every stored customer record.
An active member is a Glow member with a point balance greater than 0.
For example:
A customer profile with
0points does not count as an active member.A customer who earns order points counts as active.
A new member who receives signup points may count as active right away.
A customer whose points expire or are adjusted back to
0no longer counts as active.
If you want fewer customers to become active automatically, check whether signup points are enabled and whether order earning is awarding points to the types of customers you want in the program.
Block new member creation for unwanted emails
Use this when you want to stop new Glow members from being created for certain addresses or domains, such as test accounts, temporary email domains, bot-created customers, or marketplace-style addresses.
In Glow, go to Settings > Account Settings > Behavior.
Under Data Handling, set Block New Member Creation by Email to Yes, then add:
Blocked Exact Emails for specific addresses.
Blocked Domains for every address on a domain.
Blocked Regex Patterns only when you need advanced matching.
The blocklist applies to new member creation. It does not delete existing members or remove points that have already been awarded.
Exclude an existing member from loyalty
If a member already exists and should not participate in the loyalty program, open their member profile in Glow.
Click Edit Glow Customer Details, then check Exclude Member from Loyalty Program.
An excluded member will not earn points, redeem rewards, or receive loyalty notifications.
What not to use for this
The Save User Information setting controls how much customer data Glow stores from Shopify. If you set it to No, Glow stores the customer's email address and phone number when available, but not their name or other Shopify data.
That setting does not stop member creation by itself. Use Block New Member Creation by Email for new blocked addresses, and use Exclude Member from Loyalty Program for existing members.
When to contact support
Contact Glow support if members are still being created after you enabled the blocklist, or if you are unsure which Shopify or Glow event created the member.
Include:
The customer email address or domain you expected to block.
Whether the customer placed an order, signed in, opened the widget, or was added another way.
A screenshot of your Block New Member Creation by Email settings.
A link or screenshot for the member profile in Glow.
