Preventing your Emails from being received into Spam Internet Service Providers (ISPs), like Google, Yahoo, and Microsoft, use different types of authentication as a way to scan incoming emails for spam. Emails that fail this authentication are more likely to end up in a spam or junk folder. Because Launchmetrics is sending emails on your behalf, emails sent from the system look “unsafe” to recipients unless authentication is in place- especially to email addresses associated to big corporations who have their own set of email security in place.
