The Customer Blocklist (dashboard → Payments → Blocklist) lets you block customers from making payments. Blocking is by email address — a blocked email cannot complete a payment on your account.

Note: The blocklist matches on customer email only. Card numbers, countries, and IP addresses are not blocked here.

Blocking a customer

Click Block Customer, then enter the customer's email and a reason:

Reason	Use when
Fraud / Chargeback Risk	The customer is associated with fraud or chargeback risk.
Platform abuse	The customer has abused your platform's terms.
Duplicated account	The customer is operating duplicate accounts.
Self-exclusion	The customer asked to be excluded.
Other	Any other reason — a short free-text note is required.

Each blocklist entry appears in the table with the Email, Reason, and the date it was Added, plus actions to edit the reason or remove the entry.

Note: Managing the blocklist (add / edit / remove) requires an Owner, Editor, or Operator role. Other roles have read-only access.

Bulk upload (CSV)

To block or unblock many customers at once, use Upload Blocklist CSV:

Download the template. Its columns are the customer email, an action (add, remove, or update), and a reason.
Upload your file. Accepted format is .csv only, up to 5 MB and 500 rows.
Review the results summary — counts of Added, Updated, Removed, and Failed, with a per-row status so you can fix any rows that didn't apply.
