Notes on Capabilities
DMARC: WPEngine supports full DMARC compliance.
DKIM: Contact WPEngine support for DKIM configuration.
SPF: Add 'include:sendgrid.net' and 'include:mailgun.org' to your SPF record. WPEngine uses either SendGrid or Mailgun, depending on the types of emails being sent. As including the whole ranges of companies like SendGrid and Mailgun authorizes much more than you actually need, feel free to contact WPEngine support requesting a reduced list of IPs to include opposed to whole networks.
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.
