Spam emails are unsolicited electronic messages typically used to conduct phishing, distribute malware, or execute fraudulent schemes. These emails are designed to deceive recipients into sharing sensitive information or triggering harmful downloads. A frequent method used to source recipients is email scraping, a process where automated bots extract email addresses from websites to create mailing lists for bulk spam delivery. This tactic increases exposure to cyberattacks and undermines inbox security.
Spam emails can compromise security and disrupt operations. These messages often contain malicious content, impersonate legitimate sources, or request sensitive data under false pretences. Forwarding spam internally increases the risk of exposure and can weaken email security systems.
Spam emails often follow identifiable patterns designed to mislead recipients and extract personal or financial information. Recognising these categories is critical to improving detection and response.
Identifying spam requires close inspection of both the sender and the message content. Indicators of spam include irregular formatting, misleading language, and attempts to create urgency or induce panic. Avoid engaging with suspicious messages to reduce exposure to threats.
Reducing spam requires consistent application of email hygiene practices. Users should minimise exposure, limit engagement with unknown senders, and secure their accounts using established safeguards.
Third-party spam filters offer an additional layer of protection by identifying and blocking unsolicited or harmful messages before they reach the inbox. These tools use algorithms and threat intelligence to detect spam indicators and reduce user exposure.

Organisations may choose between self-hosted email systems for greater data control or managed cloud-based solutions for operational efficiency. Rubix Studios provides managed service provider (MSP) support for secure, compliant cloud-based email hosting.
All Rubix Studios MSP services require email subscriptions to be initiated through Rubix Studios to establish direct service management and support.
Chat solutions help reduce exposure to spam by limiting the use of public-facing email addresses. By replacing contact forms with real-time communication, these tools lower the risk of email scraping by automated bots.
To further protect forms from bot activity, implement anti-bot mechanisms such as Google Captcha or Cloudflare Turnstile. These tools help secure website input fields and reduce automated scraping attempts.
Cloudflare provides integrated tools to prevent email scraping and reduce spam exposure. Its features work by limiting automated access to email addresses and securing web forms against malicious traffic.
Features
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps prevent spoofing, phishing, and other forms of email fraud. It operates in conjunction with SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify that emails are sent from authorised sources.
To configure DMARC, add a DNS TXT record to your domain's DNS settings via your domain registrar or DNS hosting provider.
Configuration
v=DMARC1; p=none; rua=mailto:your@email.com; ruf=mailto:your@email.com; fo=0Replace your@email.com with the address designated to receive DMARC reports.
v: Protocol version. Always set to DMARC1.
p: Policy for handling unauthenticated messages:
rua: Address to receive aggregate reports.
ruf: Address to receive forensic reports.
fo: Forensic options, specifying when forensic reports are generated. fo=0 sends reports for all failures.
Monitor only
v=DMARC1; p=none; rua=mailto:reports@example.com; ruf=mailto:alerts@example.com; fo=0 Quarantine failed
v=DMARC1; p=quarantine; rua=mailto:reports@example.com; ruf=mailto:alerts@example.com; fo=0 Reject unauthenticated
v=DMARC1; p=reject; rua=mailto:reports@example.com; ruf=mailto:alerts@example.com; fo=0 Effective spam control requires a multi-layered approach combining user vigilance, technical safeguards, and policy enforcement. From identifying fraudulent messages and deploying reliable spam filters to configuring authentication protocols like DMARC, every measure contributes to stronger email security and improved operational integrity.
Organisations should regularly review and update their email protection strategies to address evolving threats. Managed email services, anti-scraping tools, and structured communication systems further reduce exposure and support compliance.
