Definitions, as per Wikipedia:
Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses.
DomainKeys Identified Mail (DKIM) is a method for associating a domain name with an email message, thereby allowing a person, role, or organization to claim some responsibility for the message.
We do not currently support custom DKIM keys for most accounts because we sign with our own. We do support DKIM for Teams accounts.
- A good testing tool for SPF can be found here.

If you have any questions about modifying your SPF records for BombBomb emails or setting up DKIM for your team, please contact us as email@example.com to speak with our Deliverability department. These records can be messed up easily, so it is imperative you speak with our Deliverability specialists if you think you need to do this.
