How Spam on Shared Hosting Gets You Blacklisted
Shared Server Spam: How It Can Get Your IP Blacklisted (and What to Do About It)
Shared server spam is one of the biggest risks of shared hosting.
If just one account on your server is compromised, your IP and even your domain name
can get blacklisted — affecting your emails, SEO rankings, and online reputation.
In this article, we’ll explain:
- How shared server spam leads to IP and domain blacklisting
- The dangers of using nulled WordPress themes/scripts
- What Aekpani does to protect clients (including email limits)
- Why upgrading to a Dedicated IP or VPS is the best long-term solution
What is IP and Domain Blacklisting?
An IP blacklist is a database used by ISPs, mail providers, and security systems
to block servers suspected of sending spam. Once blacklisted, all outgoing email from that IP will
be blocked or marked as spam.
But it doesn’t stop there:
- Some providers also enforce a domain blacklist, blocking the entire domain name
if it’s associated with spam activity. - This means your brand’s domain reputation can be damaged, not just the server IP.
How Shared Server Spam Gets You Blacklisted
On shared hosting, multiple users share the same IP. If one account is compromised:
- Hackers use it to send spam emails.
- Security systems detect spam and flag the shared server IP.
- RBLs may also blacklist associated domains.
- Every customer on that server suffers — even if they did nothing wrong.
Result: Your emails bounce, your SEO drops, and your brand loses trust due to
shared server spam.
The Hidden Dangers of Nulled WordPress Themes and Scripts
Many website owners try to save money by installing
nulled WordPress themes or scripts.
But this is one of the leading causes of shared server spam.
Why it’s risky:
- Nulled files often contain backdoors and malware.
- Hackers use them to send spam emails from your account.
- Both your IP and domain can end up blacklisted.
- Cleaning and recovery is costly and time-consuming.
Always use licensed, genuine themes and plugins.
The short-term savings of nulled scripts aren’t worth permanent blacklisting risks.
Aekpani’s Email Policy (Protecting You from Shared Server Spam)
To minimize the risk of IP blacklisted shared hosting, Aekpani enforces a
default outgoing email limit of 50 emails per hour per domain.
Why?
- Prevents hacked accounts from sending thousands of spam emails.
- Reduces the risk of the entire shared server IP being blacklisted.
- Ensures fair use of server resources for all clients.
❌ We do not support bulk mailing on shared hosting.
For large volumes, use professional email services like Google Workspace, Microsoft 365, or transactional
providers (Amazon SES, Mailgun, SendGrid).
What to Do If You’re Blacklisted
- Scan your website for malware and remove infections.
- Remove nulled scripts or suspicious plugins immediately.
- Reset email passwords and enable 2FA if possible.
- Check blacklists with
MXToolbox
or Spamhaus. - Request delisting after fixing the issue.
- If issues persist, migrate to a Dedicated IP or VPS.
Dedicated IP vs Shared Hosting
When comparing dedicated IP vs shared hosting,
the difference is clear: with a dedicated IP, your email reputation depends only on your activity,
not on other users on the server.
Benefits of a Dedicated IP
- Your email reputation is fully isolated.
- Fewer email deliverability issues.
- Best for invoices, client communication, and sensitive business emails.
VPS Hosting Benefits
- Your resources (CPU, RAM, IP) are completely dedicated.
- Stronger security and customization.
- Scalable as your business grows.
- No risks from shared server spam.

Conclusion
Shared server spam doesn’t just hurt one website — it can
damage every domain on the same server. Once blacklisted, recovery is slow and harmful to your brand.
The best protection is prevention:
- Avoid nulled themes/scripts.
- Follow security best practices.
- Respect Aekpani’s outgoing email limits.
- Upgrade to a Dedicated IP or VPS to protect your reputation.
