In the present situation, Intercom handles SPF authentication for outbound emails themselves since they don’t allow emails to be sent using a return-path address that isn’t their own. Hence if you are using Intercom as a sending source, you don’t need to manually configure SPF.
However, SPF alone isn’t enough to protect your domain from the malicious intentions of threat actors. To maximize your protection against email abuse and impersonation, make your emails DMARC compliant today by signing up for a free DMARC trial!
