How did my domain get blacklisted?

Common causes include sending spam (even unintentionally), compromised email accounts or servers, shared hosting with bad neighbors, misconfigured email authentication, malware infections, and bulk email practices without proper opt-in. Our tool helps identify the likely cause.

How do I get delisted from a blacklist?

First, fix the underlying issue (compromised account, misconfigured server, etc.). Then visit each blacklist's website and follow their delisting process. Some lists delist automatically after the issue is resolved. Our report provides direct links to delisting procedures.

How long does delisting take?

Delisting times vary: some lists remove entries within hours of a request, others may take 24-72 hours, and some have mandatory waiting periods of 1-2 weeks. A few lists (like Spamhaus) require manual review. Address the root cause first to prevent re-listing.

Does blacklisting affect SEO?

While blacklists primarily affect email deliverability, Google Safe Browsing can flag your site as dangerous, which severely impacts SEO rankings. Malware and phishing listings can trigger browser warnings for visitors. Our tool checks both email and web-facing blacklists.

How often should I check my blacklist status?

Check at least weekly, or more frequently if you send high-volume email. Vysiro offers continuous monitoring that alerts you immediately if your domain or IP appears on any blacklist, allowing you to respond before deliverability is impacted.

Frequently Asked Questions

Everything you need to know about blacklist checking

A DNS blacklist is a database of IP addresses and domains known to send spam or malicious content. Mail servers query these lists to decide whether to accept or reject incoming email. Being listed can cause your emails to be blocked or sent to spam folders.
