How to Use SPF Records to Improve Email Deliverability
The Sender Policy Framework (SPF) record is a DNS record that validates the domain name from which email messages are delivered, thereby preventing spoofing and phishing. SPF compares the sender’s IP address to the owner of the sending domain.
Update Existing SPF Record
If your domain already has an SPF record, you can simply update it. You are only permitted to have one SPF record for a domain, so do not create another.
For example, if your current record is as follows:
v=spf1 include:spf.protection.outlook.com -all
Include the spf.bolddesk.com record in the above TXT record like below,
v=spf1 include:spf.protection.outlook.com include:spf.bolddesk.com -all
Create a New SPF Record
If your DNS hosting provider does not have an SPF record, you will need to create one in order to include our servers. SPF records are added as a TXT record type. create a new record and update the below value,
v=spf1 include:spf.bolddesk.com ~all
It may take some time for new SPF records to take effect; you may verify your domain in tools like MX Toolbox.
If you’re having trouble setting up the SPF, here are additional detailed instructions for each DNS provider,
