DKIM (acronym for Domain Keys Identification Mail) is a method used to prevent people to fake email identities. Analyzing the domain part of the sending address – @domain.com – it verifies whether a message comes from the claimed source or not: basically, it’s an email authentication service.
DKIM is extremely useful. In fact, email is pretty easy to spoof: you have probably receveid lots of messages that pretended to be sent from your bank or from a Post Office – when they were phishing instead.
With DKIM, you get a digital signature that proofs your identity and avoid you to fall into spam filters: so this will kill phishing, increase legitimate email delivery, and enhance the general trust in this form of communication.
turboSMTP offers a default authentication process through its servers, but we strongly recommend to add a record to your DNS settings in order to improve your email delivery rate. This is a crucial technical requirement to make it sure that all your newsletters are correctly delivered to all intended recipients.
