Why BIMI email clients matter
BIMI email clients are helping companies strengthen security and boost brand visibility in email inboxes. The amount of BIMI email clients is increasing, allowing more businesses to enhance their email marketing impact and deliverability.
Implementing the standard shows your organization’s commitment to security and brand integrity.
