How to Reduce or Eliminate Spam Emails Using a Spam Filter

Spam email is electronic junk mail or any unsolicited commercial email. Be cautious of spam emails, as they can be harmful. They may contain harmful links that can infect your computer with malware. You should avoid clicking on any links in spam emails, especially those that sound urgent; for more information on how to identify spam, check out How to Detect Unwanted Email.

Spam can't be eliminated entirely, but reducing it is possible. Unfortunately, stopping unsolicited emails from piling up in your inbox is not a one-click solution—it's a balance between prevention techniques and email filters.

How to Protect Yourself from Spam Email

To safeguard your email address against unwanted attention from spammers and cyber threats, it's crucial to maintain its confidentiality. Share your email address exclusively with trusted individuals, refraining from publicizing it on platforms like websites, chat rooms, or forums. Instead, consider employing a contact form on your website as a more secure means of communication. Additionally, where feasible, activate domain privacy for all your domains to shield your email address from potential spammers.

What to Do if You Receive Spam Email

If you come across a spam email in your inbox, it's advisable to report it to your email provider. Almost all email providers offer the option to report spam emails as junk or spam. Reporting spam enhances the efficacy of the antispam filters and prevents future spam messages from entering your inbox.

Spam Filters

The subsequent action involves configuring a spam filter to further combat spam. It's advisable to establish this filter immediately upon accessing your new hosting account, significantly reducing the likelihood of encountering spam. Even if you've already faced a spam onslaught, implementing a spam filter at any time will promptly commence its protective measures.

When it comes to spam filters, we propose considering the following options:

  • SpamAssassin: This free spam filter identifies common spam phrases and formats, assigning a spam score accordingly. While SpamAssassin requires some initial setup, adjustments to your email settings or the addition of supplementary email filters may be necessary to accommodate its changes. Regular updates may also be required to counter emerging spam tactics.

    Note: Refer to our SpamAssassin article for comprehensive details.

  • SpamExperts: Offering a more streamlined solution, SpamExperts boasts advanced filtering capabilities, capable of eliminating 99.98% of unsolicited bulk emails. Operating at the domain level, SpamExperts allows for personalized rules to be set for individual email addresses.

    Note: For more information, please see SpamExperts: Simply Spam Free and SpamExperts: Features and Functions. Note that these articles are for information purposes only, as we no longer offer SpamExperts.

While both spam filters are effective, we recommend only using one. SpamExperts is best for more advanced filtering if your spam filtering needs are greater. SpamAssassin is the better choice if you want to protect against basic spam.

In addition to managing spam with SPF records, Bluehost also allows you to change your Domain Name System (DNS) settings. This can be helpful for a variety of reasons, such as pointing your domain name to a new website host or setting up email for your domain.

Here's a quick recap of SPF records:

  • SPF records are helpful when it comes to spam filtering.
  • There are three common SPF record policies:
    • all "Hard Fail" indicates that all mail not on the allowlist is rejected.
    • ~all "Soft Fail" indicates that it accepts mail that is not on the allowlist but handles it carefully (e.g., may send it to spam).
    • ?all "Neutral" indicates no policy for servers not on the list; it allows all mail. This is the default configuration.

For more information on how to change your DNS settings or manage SPF records, please refer to Bluehost's knowledge base articles:


Prevent spam email and protect your computer from malware. Be cautious of spam emails, which can be harmful and contain dangerous links. It's important to keep your email address private, avoid posting it on public websites, and enable domain privacy to prevent your email from being targeted by spammers. Additionally, upgrading to a professional email hosting service can give you even stronger defenses against spam.
