If you’ve chosen to send Collaborate emails from your team’s email domain, rather than the default address firstname.lastname@example.org, you will want to set up email authentication to help ensure your emails reach the inbox of your recipient.
Email Service Providers (ESPs) rely on authentication to fight spam, prevent phishing, and provide protection against other forms of fraud, which makes it an important step to take. Many ISPs use authentication to help track sender reputation. Authenticating your email domains will reduce the chances of your emails going to your recipients’ spam folders. Finally, some email clients will show a warning message if they are unable to verify the sender is sending from an approved IP address. For the best customer experience, be sure authentication is set up so those alerts don’t show.
Once domain authentication has been set up, emails will be sent with a signature that matches a record in your DNS (Domain Name Servers). This way, ESPs have a way to ensure the sender is legitimate. Emails that do not pass authentication may be blocked or put through additional scrutinization, and in some cases will not make it to the recipients’ inbox.
