DKIM (DomainKeys Identified Mail) is an email authentication method used to verify the authenticity and integrity of an email message. It allows the recipient’s email server to check if an email was genuinely sent by the claimed sender and if it was altered during transit.

Act Marketing Automation is an email marketing service that helps businesses send marketing emails to their contacts via Act CRM. DKIM can be used with Act Marketing Automation to enhance email deliverability and improve the chances of emails reaching the recipients’ inboxes instead of being flagged as spam.

When DKIM is implemented with Act Marketing Automation, a digital signature is added to each outgoing email. This signature is generated using cryptographic techniques and is based on the sending domain. When the recipient’s email server receives an email sent through Act Marketing Automation, it can use the DKIM signature to verify that the email was indeed sent by the claimed sender and that it has not been tampered with during transmission.

By implementing DKIM, Act Marketing Automation helps businesses establish trust with email recipients and reduces the likelihood of their emails being marked as spam. This can improve email deliverability rates and ensure that important messages and marketing campaigns reach the intended audience.
