The first survey conducted in July 2025 confirmed high security awareness among email recipients and the contribution of BIMI to intuitive legitimacy judgment. However, the adoption rates of DMARC and BIMI among email senders remained low. This survey was conducted to continuously track how the situation has changed since then and to clarify the effects of BIMI and the actual implementation status and challenges on the sender side in more detail.
