SPF (or Sender Policy Framework) is one of the most commonly used forms of authentication. SPF sort of functions like a permission slip. Your domain lists servers that are authorized to send on your behalf and recipient email servers check who is sending against that "permission slip"
To ensure the best level of deliverability while using rezora, we strongly recommend making sure your SPF record is configured in a way to allow rezora's sending servers to send on behalf of you and your agents. Without this setting in place, receiving email servers may be less trustful of the emails you are sending, potentially causing degraded deliverability.
This is done by adding include:sendgrid.net before the final all mechanism in your SPF record.
For example, if your existing SPF record is:
- v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com ~all
the new record might look like:
- v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com include:sendgrid.net ~all
If SPF is like a permission slip, DKIM is more of a secret passphrase/signature. It is a digital signature added to outgoing messages that lets receiving servers know that the email is actually from you (not someone posing as you).
You may need to see if your domain has DKIM set up. DKIM is a little more complicated to set up than SPF as we need to generate a unique signature to share with your team directly so they can set it up.
If you do have DKIM set up, please let us know so we can loop in our engineering team to generate and send your team what they need.
Email us at email@example.com if you have DKIM for your domain and we'll get to work getting you the information that you'll need!
