Why Spam Emails Are a Big Problem for Businesses

Spam isn’t just annoying, it can be dangerous:

Phishing emails trick employees into giving away passwords and company data
Malware attachments can infect your network
Email overload lowers productivity and clutters inboxes
Accidental clicks can cause major breaches and financial losses

According to cybersecurity experts, over 85% of cyberattacks start with email. So, taking email security seriously is no longer optional.

How to Stop Spam Emails in Your Business Inbox

1. Use a Business-Grade Email Security Solution

Basic spam filters often miss sophisticated threats. To protect your inbox, invest in an advanced email filtering solution like MailSafi Email Security, which offers:

99% spam detection rate
Real-time phishing & malware filtering
Protection from spoofing, ransomware, and BEC
Compatibility with Microsoft 365, Google Workspace, Zimbra, cPanel & more

Tip: Choose a solution that works across multiple platforms and includes automatic updates to fight evolving threats.

2. Enable SPF, DKIM & DMARC on Your Domain

These are email authentication protocols that:

Prove that your business is the real sender
Help block forged or spoofed emails pretending to be from you
Reduce spam from your domain
Increase email deliverability and protect your reputation

If you’re not sure how to set this up, ask your IT team or email provider. MailSafi includes this setup with hosting.

3. Train Your Team on Email Security Awareness

Your employees are the first line of defense. Even the best software won’t help if users don’t recognize threats. Training should cover:

How to spot phishing emails
Not clicking on unknown links or attachments
How to report suspicious messages
Using strong passwords and two-factor authentication (2FA)

Consider enrolling your team in Kaluari’s Cybersecurity Awareness Training to stay updated on the latest threats.

4. Archive and Backup All Emails

Accidentally deleted an email or fell for a phishing scam? With M@ilSafi Email Archiving, you’ll have:

A tamper-proof copy of all inbound & outbound emails
Easy search and retrieval
7+ years of retention for legal & business needs

Email archiving doesn’t just help with compliance, it adds a powerful layer of protection against loss and manipulation.

5. Limit Use of Business Email Addresses

Avoid publishing your email addresses in plain text on your website or social media. Spammers often scrape public sites for addresses. Use:

Web forms instead of emails
Email obfuscation tools
Generic contact addresses (e.g., info@yourcompany.com) instead of personal emails

6. Separate Marketing & Operational Emails

Segment your email infrastructure. Use different domains/subdomains for:

Marketing emails (e.g., newsletter@marketing.yourcompany.com)
Transactional emails (e.g., alerts@yourcompany.com)
Internal operations (e.g., john@yourcompany.com)

This structure improves security, reduces risk, and enhances deliverability.

7. Partner with a Secure Email Hosting Provider

Free or basic email services aren’t designed for business-grade protection. M@ilSafi offers:

Secure, reliable cloud email hosting
Spam filtering & virus protection built-in
File sharing, calendar, collaboration, and backup
