Combating a relentless spammer requires a comprehensive strategy involving several steps. Begin by reporting the spammer to Google. If possible, identify the ESP and file a complaint. Utilize Gmail's blocking and filtering features, including wildcards for domain blocking. For enhanced security, use temporary email addresses for new sign-ups and regularly review email privacy settings. Protect your domain by implementing DMARC records. Report phishing attempts to Google at abuse@google.com. Continuously update blocklists and consider advanced filtering techniques. Be cautious of suspicious emails and verify sender addresses.

To combat relentless spammers who switch domains and send via Google Workspace, a multi-faceted approach is necessary. Reporting the spammer to Google, identifying the ESP for complaint, and utilizing Gmail's filtering capabilities (including wildcards) are essential. Furthermore, employ best practices such as using temporary email addresses, reviewing privacy settings, and unsubscribing from unwanted lists. For domain protection, implement DMARC records. Report phishing attempts to Google via abuse@google.com.

Combating persistent spammers requires a multi-layered approach. While reporting to hosting providers like AWS might be ineffective, blocking the spammer and reporting abuse to domain registrars like Namecheap is advised. Experts emphasize advanced filtering, continuous blocklist updates, and machine learning for pattern identification. Tracking and reporting spoofed or compromised accounts to abuse desks and Google Workspace are also crucial for prevention.

Google Workspace Admin Help provides several methods to stop spammers. Users can directly block senders in Gmail. Admins can create email filters based on sender, recipient, subject, or keywords to manage emails automatically. Google Safety Center advises caution with suspicious emails, urging users to verify senders and report phishing attempts.
