Blacklist checker — FAQ

What is an email blacklist (DNSBL)?+

A DNSBL is a real-time list of IPs and domains flagged for sending spam. Mail servers check these lists and may reject or junk mail from listed senders.

Why is my IP or domain blacklisted?+

Common causes: a compromised account sending spam, a misconfigured mail server, shared-IP neighbours, or past abuse. The detailed results show which lists flagged you and where to request delisting.

How do I get removed from a blacklist?+

Each blacklist has its own delisting process — fix the underlying cause first (secure accounts, fix DNS/SPF/DKIM), then submit a removal request via the link shown in the results.

Does The PowerHost hosting avoid blacklists?+

Our hosting uses clean IPs, Imunify360 and outbound spam controls to keep sender reputation healthy — and our team helps if you ever get listed.
