How to Set Up/Modify SPF for SendinBlue
The following description addresses how to update a Domain Name Service (DNS) record to use SPF with your custom domain in SendinBlue.
SendinBlue utilizes an include mechanism during the set-up process. For example, if you do not have an SPF record on your domain, the following scenario is the most common and would pass SPF:
v=spf1 include:sendinblue.com ~all
If you do already have an SPF record on your domain, simply add the following to it:
include:sendinblue.com
To create an SPF record for your domain name, follow these steps:
1. Log in to control panel for your domain DNS host
2. Create a record with the following specifications:
v=spf1 include:sendinblue.com ~all
3. Decide how you want to enforce SPF failures:
~all results in a soft fail (not authorized, but not explicitly unauthorized)
-all results in a hard fail (unauthorized)
?all is neutral (similar to no policy)
As shown above, enter your choice after v=spf1 include:sendinblue.com
4. Save changes
