Store Blacklist
Use the SellApp blacklist to block risky customers, IP addresses, countries, ASNs, and email patterns before checkout.
The Blacklist helps you reduce fraud and abuse before it reaches checkout. Use it to block customers or traffic patterns that should not be allowed to buy from your store.
Open Blacklist to manage entries.
Blacklist types
SellApp supports these blacklist types:
- Email for a specific email address.
- Wildcard email for a pattern across multiple emails.
- IP for a specific IP address.
- Country for country-level blocking.
- ASN for blocking a network or hosting provider range.
Each entry also includes a description. Write the reason clearly so another team member understands why the block exists later.
When to add an entry
Add a blacklist entry when you see repeated fraud attempts, abuse, chargeback patterns, spam tickets, bot traffic, or traffic from a source that should never purchase.
Avoid overly broad blocks unless the risk is clear. A country or ASN block can stop legitimate customers too, so use specific email or IP blocks when the issue is narrow.
Review periodically
Blacklist entries can outlive the original issue. Review older entries from time to time, especially broad wildcard, country, and ASN blocks.
If a real customer says they cannot checkout, check the Blacklist before assuming the payment method is failing. This can save time when troubleshooting blocked payments or failed purchase attempts.
