SPF: Sender Policy Framework
Lets ESPs know what servers are authorized to send email from a domain. Basically just a list of approved senders.
DKIM: DomainKeys Identified Mail
Enables ESPs to verify the sending domain of an email and that its contents have not been altered-in-transit. The sender digitally signs the email using a private key that recipients can authenticate via a public key.
DMARC: Domain-based Message Authentication, Reporting & Conformance
Addresses shortcomings in SPF and DKIM by tying those standards to the "From" domain. Additionally, provides domain owners with reporting on who is sending from their domain, and authority to dictate how it is handled.
Domain owners can publish a DMARC record which tells ESPs that SPF and DKIM records must be in "alignment" and what to do if they're not.
You should set up a DMARC policy for your domain. You can send DMARC compliant emails from all the transactional email providers discussed.
You also should to add include:sendgrid.net to the SPF record of your root domain!
