Notes on Capabilities
DMARC: Our data indicates Everbridge supports DMARC compliance via SPF.
DKIM: Contact Everbridge to ask about their DKIM capabilities.
SPF: Everbridge advises to add 'include:everbridge.net' to your SPF record, however note this pulls in two additional includes. Although they also advise to use a subdomain (which would help a lot in avoiding the 10 DNS lookup limit), it's still worth getting in touch with Everbridge and understanding if there's a lesser authorization to use.

When deploying DMARC, domain owners often find new sources of email.
Domain owners then wonder if the source is capable of sending DMARC compliant email.
