Summary
Dealing with a relentless spammer who constantly switches domains and sends emails via Google Workspace (formerly G Suite) can be incredibly frustrating. This challenge highlights the difficulty in combating persistent abuse when perpetrators leverage legitimate platforms and frequently change their digital footprint to evade detection.
Key findings
- Domain and address switching: Spammers often rotate domains and email addresses, making traditional blocking methods less effective as a long-term solution.
- Google Workspace as a vector: The use of legitimate services like Google Workspace adds complexity, as direct blocking of Google's IPs or domains is not feasible.
- Reporting to Google: Reporting abuse directly to Google is a critical step, as they have policies against spam and can take action against their users.
- Email headers: Analyzing email headers is crucial for identifying the true origin, sending platform, and any underlying patterns or identifiers.
Key considerations
- Persistent effort: Stopping relentless spammers requires persistent monitoring and reporting, as they will often adapt their tactics.
- Leverage authentication: Understanding email authentication protocols like SPF, DKIM, and DMARC can help you identify legitimate senders versus spoofers.
- Domain reputation: While you cannot control the spammer's domain reputation, understanding how domain reputation works can inform your strategy.
- Formal complaints: Submitting abuse reports to the spammer's ESP (Email Service Provider) or their domain registrar (e.g., via Google's abuse reporting form) can lead to service termination for the spammer.
What email marketers say
Email marketers often face the challenge of dealing with persistent spammers, both as victims and as professionals seeking to maintain their own sending reputation. Their insights highlight the practical difficulties and the often-limited immediate solutions available when spammers are adaptive and leveraging major platforms like Google Workspace. The consensus is often to use a multi-pronged approach involving direct blocking, reporting, and careful monitoring.
Key opinions
- Headers are key: Many marketers emphasize the importance of examining email headers to uncover details about the sender's true origin and ESP.
- Reporting to providers: There's a strong sentiment that reporting spam directly to the ESP, registrar, or even the hosting provider (like AWS) is essential, despite the potential for slow responses.
- Block if possible: Implementing internal blocks for specific domains or addresses is a common first line of defense, even if spammers frequently switch tactics.
- Relentless nature: Marketers acknowledge the persistent and frustrating nature of these types of spammers who adapt quickly.
Key considerations
- Understand the platform: If spammers are using platforms like Google Workspace or AWS, understand their abuse policies and reporting mechanisms.
- Automate blocking where feasible: Consider if your email system can automatically prevent sending emails to specific domains or patterns identified in the spam.
- Patience and persistence: It may take time for abuse reports to result in action, especially with large providers, so consistent reporting is vital.
- Identify blocklist impact: While it's the spammer's problem, general knowledge of how email blocklists work can help understand ISP reactions.
- Trace headers: Always look at email headers to find the most accurate information about the sender and their infrastructure.
Marketer view
An Email Geeks marketer advises users to paste email headers for analysis. This step is critical for identifying the underlying ESP or infrastructure used by the spammer, which can then guide where to file a complaint. Without headers, it is much harder to pinpoint the source effectively.
Marketer view
An Email Geeks marketer points out that if the spammer's domains are hosted on AWS, getting a quick resolution can be difficult. While AWS does have abuse policies, their scale can make individual complaints slow to process. This highlights a common frustration with large hosting providers.
What the experts say
Email deliverability experts highlight that persistent spam from platforms like Google Workspace often stems from compromised accounts or users abusing the service. Their advice focuses on leveraging official reporting channels, understanding technical indicators, and recognizing the limitations of recipient-side blocking against sophisticated spammers who employ domain rotation and other evasion techniques. They stress the importance of collaboration with service providers to enforce acceptable use policies.
Key opinions
- Google's role: Experts agree that Google has a responsibility and mechanisms to address abuse on their platform. Direct reporting is crucial.
- Domain reputation matters: Even with domain switching, a spammer's overall domain reputation will eventually suffer, impacting their deliverability. This can be monitored using tools like Google Postmaster Tools.
- Authentication standards: Strong email authentication (SPF, DKIM, DMARC) helps mail providers distinguish legitimate mail from fraudulent mail, although spammers using Google Workspace might have valid authentication for their Google domains.
- Abuse desks: Reporting to relevant abuse desks (ISP, ESP, registrar) remains the most effective long-term strategy for getting spammers taken offline.
Key considerations
- Identify patterns: Look for subtle patterns in the spam emails, even if domains change, such as consistent subject lines, content, or underlying IPs that might be unique to the spammer.
- Leverage DMARC reports: If you control a receiving domain, DMARC aggregate reports can provide insights into sources attempting to spoof your domain or send on behalf of domains they shouldn't.
- Industry collaboration: The Messaging, Malware and Mobile Anti-Abuse Working Group (M3AAWG) offers best practices for combating abuse that can be adapted by organizations dealing with persistent spammers.
- Spam trap networks: Spammers who hit spam trap networks will eventually face severe deliverability issues, reinforcing the long-term impact of their actions.
Expert view
An expert from Spam Resource stresses that persistent spammers, especially those using domain rotation, are a significant challenge because they constantly try to evade detection. Effective defense requires a combination of automated filtering and manual abuse reporting to catch new iterations of their campaigns.
Expert view
An expert from Word to the Wise explains that email service providers like Google Workspace have robust abuse desks that investigate spam complaints. While it might take time, consistent reporting with detailed headers is the most effective way to get spammers' accounts terminated.
What the documentation says
Official documentation from major email providers and internet standards bodies outlines the expected behavior for email sending and the processes for reporting abuse. These documents provide the foundational rules that legitimate senders and service providers are expected to follow, and they serve as the basis for anti-spam measures. When spammers leverage platforms like Google Workspace, their actions violate the platform's terms of service, which is a key leverage point for reporting.
Key findings
- Google's acceptable use policy: Google Workspace has strict policies against sending unsolicited bulk email or engaging in practices that harm other users. Violations can lead to account suspension.
- Reporting mechanisms: Major ISPs and service providers provide clear channels for users to report spam and abuse. These reports are critical for their automated and manual review processes.
- Domain registration data: ICANN regulations require domain registrars to maintain contact information for domain owners, which can be used to report abuse if direct email channels fail.
- Email authentication importance: RFCs define how email authentication standards like SPF, DKIM, and DMARC should be implemented, helping distinguish legitimate traffic from abusive patterns, even if spammers try to mimic legitimate senders.
Key considerations
- Detailed reporting: When reporting spam, providing complete email headers, the sender's email address, and the content of the spam message increases the likelihood of effective action by the service provider.
- Terms of service: Familiarize yourself with the terms of service of major providers like Google Workspace; this empowers your abuse reports by showing direct violations.
- Impact of blocklists: Documentation clarifies that being placed on a blocklist is a direct consequence of abusive sending, significantly hindering deliverability.
- Identifying suspicious domains: Resources often describe how to identify suspicious domains that spammers frequently use, which can inform your filtering rules.
- RFC compliance: The Internet Engineering Task Force's (IETF) RFC 5322 (Internet Message Format) defines the standard for email messages, and violations of its principles are often indicative of spam.
Technical article
Google's Acceptable Use Policy specifies that users must not transmit spam, bulk, or unsolicited emails. Violations of this policy are grounds for suspension or termination of Google Workspace accounts. This highlights the importance of reporting to Google directly when their platform is abused.
Technical article
RFC 2822, defining the Internet Message Format, outlines structural requirements for email messages, including headers and body. Spammers often manipulate these headers or ignore standards, which can be indicators for sophisticated spam filters to flag their messages as non-compliant.
