The ease of creating numerous free accounts allows them to circumvent sending limits and send high volumes of emails. Some claim they use Gmail because their own domains are blocked.

What the experts say
3 expert opinions
Experts suggest that spammers use Gmail addresses for business outreach because, despite Gmail's efforts to block spam from Google Workspace accounts, some spammers are still using regular @gmail.com addresses. These addresses may provide deliverability benefits compared to the spammer's own domains, as Gmail might not block or flag them as readily. There's a historical parallel with companies violating Google's AUP, hinting at spammers potentially exploiting loopholes or circumventing Gmail's spam detection mechanisms.
Key opinions
- Deliverability Benefits: Gmail addresses may offer better deliverability for spammers compared to their own domains, possibly due to Gmail's less aggressive spam filtering on its own domain.
- Circumvention Tactics: Spammers may be exploiting loopholes or circumventing Gmail's spam detection mechanisms, similar to past instances where companies violated Google's AUP.
- Trustworthiness Questioned: The use of generic @gmail.com addresses for business outreach raises questions about the legitimacy and trustworthiness of the sender.
- Improved Blocking of Workspace: Google has improved at blocking spam from workspace accounts but not from generic @gmail.com accounts
Key considerations
- Verify Sender: Be cautious of unsolicited business emails from generic @gmail.com addresses and verify the sender's legitimacy through alternative channels.
- Report Suspicious Activity: Report suspicious emails to Gmail to help improve spam detection and filtering accuracy.
- Monitor for AUP Violations: Stay informed about Google's AUP and potential violations that could lead to spam or abuse originating from Gmail.
- Strengthen Spam Filters: Gmail users should strengthen their individual spam filters to combat increasing spam from generic @gmail.com accounts.
