Introduction

The Email Blacklist is a suppression list. Email addresses on it don’t receive any emails sent from Yuko, such as points, reward, referral and membership emails and workflow emails. Customers on the list can still earn and redeem points as usual.

​
When to use

  • A customer has asked not to receive any emails from your loyalty program.
  • You want to keep Yuko emails away from internal, test or staff accounts.
  • You want to stop emails to a whole domain or to automated addresses, such as no-reply@ mailboxes.

​
Overview

  • An Email Blacklist Activation toggle turns the list on or off. The list starts empty and the toggle starts off.
  • Add entries with Add Manually or Upload CSV.
  • Entries can be exact addresses or patterns with a * wildcard.
  • Entries are listed under Email Address, where you can delete one or several at once.
The Email Blacklist is available on select plans. If it isn’t included in your plan, the page shows an upgrade banner.

​
Setup

1

Open Email Blacklist

Go to Apps → Yuko Loyalty → Account → Email Settings and select the Email Blacklist tab.
2

Add addresses manually

Click Add Manually. In Email addresses, enter one or more entries separated by commas. Supported formats:
  • sample@example.com blocks one exact email.
  • *@anydomain.com blocks every email from a specific domain.
  • no-reply@* blocks any email starting with no-reply@ across all domains.
3

Or upload a CSV

Click Upload CSV and drop in a .csv file of addresses. The file must be 15 KB or smaller. Click Download a sample CSV in the upload window to see the format.
4

Turn on the blacklist

Switch on Email Blacklist Activation. While it’s off, a banner warns that addresses on the list still receive emails from Yuko.

​
How it works

  • When the blacklist is on and a customer’s email matches an entry, Yuko skips the emails and workflows triggered for that customer.
  • Matching uses the exact address or your wildcard pattern.
  • Turning the toggle off keeps your list, so you can turn it back on later. Turning it off asks for confirmation.
  • The list only affects Yuko. It doesn’t change the customer’s marketing consent in Shopify or in other email tools.

​
Best practices

Add your test and staff accounts so test orders don’t send real loyalty emails.
Use wildcards carefully. *@gmail.com would stop emails to every Gmail customer.
Keep a CSV backup of large lists so you can re-upload them if needed.

​
FAQs

No. It only stops Yuko from emailing them. To remove someone from your loyalty program, use Exclude from Program on the customer in Customers.
Check that Email Blacklist Activation is switched on. The list has no effect while the toggle is off.
Delete it from the list, or select several entries and delete them together.
