SPF verification still showing a warning after SPF has been updated

Question

Why do I still see the verification warning after I've updated my external address's SPF record? 

Answer

You must retry the SPF check after updating the record to verify the SPF settings. To do so:

1. Navigate to Admin icon () > Channels > Email.
2. Select the address displaying the warning. 
3. From the options that display, select Retry next to the SPF check. 

If you see the warning still shows after doing the above, you may have an invalid record. Follow our guide, Why is my SPF record not validating? for further troubleshooting.
