Email remains a key mechanism to communicate with your business’s users. Mostly behind the scenes, email has been changing over the last 10 years. Initially created in the “trust everyone” early days of the internet, email has been shifting to thwart its exploitation by abusers, spammers, and miscreants of various stripes. The biggest step toward a trusted email environment has been the development of domain authentication for sources of email. Even if you outsource most of the heavy lifting for sending your service’s email flow, this tutorial will help you to know which questions to ask when interviewing potential vendors. If you drive your own email flows, this information will be critical to ensure that you can effectively deliver your message to your end users—reliably, safely and while protecting your brand identity.
Email authentication is an alphabet soup of IETF standards, from SMTP through the latest standard in work, DMARC. This guided tour will help you sort out how to configure your DNS and your mail systems to work with internal sources and external vendors. Ensuring that your messages adhere to the accepted industry standards and best practices will reduce the likelihood that your messages are rejected by receiver systems, and increase the reliability of communicating to your intended recipients. Authenticated email is the best protection for your brand and for your users alike.
This tutorial will cover SMTP, ESMTP, MIME, SPF, DKIM, DMARC and best practices for email sending, so that end-to-end, your message will have the best chance of getting through the gauntlet of noise that bombards most inboxes.
The tutorial will also include suggestions on how to implement these practices within an existing organization.
