One in Two Users Receive Spoofing Emails Monthly; 55.7% of Email Recipients Say Brand Logo Display Influences Email Opening Decisions

GMO Brand Security Inc. (President and CEO: Mitsuaki Nakagawa; hereinafter "GMO Brand Security"), a member of the GMO Internet Group, has conducted a survey on the adoption and impact of Brand-Logo-Enabled Email (BIMI) targeting both email recipients and email service providers. This marks the second survey following the July 2025 research (*1).

The survey results revealed that email recipients reported high concerns about spoofing emails and phishing threats, with 55.7% of respondents indicating that the display of corporate logos influences their decision to open emails. However, the adoption rate of BIMI among email service providers remains limited at 16.3%, indicating that implementation of this protective technology is still lagging significantly.
