Is Your Business Email Ending Up in Spam Folders? Find Out in 30 Seconds

Your customers aren't seeing your emails. Your invoices are being ignored. Your marketing campaigns are failing. The problem might not be your message – it could be that your domain is blacklisted.

What Is a Domain Blacklist?

A domain blacklist is like a "do not trust" list that email providers use to identify potentially harmful or spammy domains. When your domain gets blacklisted, your emails automatically go to spam folders or get blocked entirely – even if you're sending legitimate business communications.

The Hidden Cost of Being Blacklisted

Lost Sales: Customer inquiries go unanswered because they never reach your inbox
Damaged Relationships: Clients think you're ignoring their emails
Wasted Marketing: Email campaigns with 0% open rates
Cash Flow Issues: Invoice emails trapped in spam folders
Reputation Damage: Looking unprofessional to prospects and partners

Common Signs Your Domain Might Be Blacklisted

Customers say they never received your emails (but you sent them)

Why is my domain blacklisted?

Because you acted like a spammy ex who keeps texting 'Hey.' at 3AM. Mail servers ghosted you for a reason.

Bro can you remove me from the blacklist?

Sure, right after you stop using a domain that sounds like a malware link and writing subject lines like FREE iPhone 69.

So like… what now?

Now? You repent. Set up your DNS like a civilized email sender, and stop DMing strangers like it’s a pickup line.

Why are my emails dying before they reach the inbox?

Because your domain’s karma is worse than a politician's Twitter history.

How do I avoid blacklists?

Don’t send 3,000 emails about your ‘life-changing course’ at 2AM from a .xyz domain. This isn’t 2011.
