00:19 What is Sender Policy Framework (SPF)?
Sender Policy Framework (SPF) is an email authentication protocol designed to prevent email spoofing and spam. It restricts who can use an organization's domain as the sender of the email. In most phishing attacks, threat actors usually spoof the sender's email address to look official. SPF prevents that from being received.

00:37 How does SPF work?
SPF uses a Domain Name System (DNS) record that lists hosts and IP addresses that are authorized to send email for your domain. It gives a simple method for receiving mail servers to check that the host of the incoming email is authorized by the domain's administrators. That's fancy IT talk for the SPF being the bouncer checking to see if the email sender made it on the list.

01:20 Why is SPF important?
prevents spoofing
enhances deliverability
improves domain reputation
helps fight phishing attacks
supports compliance

01:30 Do I need an SPF record?
While we can't make you do anything, having an SPF record is definitely a good idea. This record protects your domain reputation. Without it, your legitimate emails could get blocked and sent to spam folders which destroys your domain rep and makes it increasingly difficult to communicate with customers and potential clients.

01:48 SPF Limitations
Like all great technology, SPF still has some limitations. It’s a DNS record, so there are length and complexity limitations.
And it can be a pain to maintain, especially for organizations with complex email infrastructures. As organizations add more email servers or thirdparty email services, keeping the SPF record up to date can become difficult. It’s also difficult for organizations who don’t have control over folks signing up for new services that might send out emails without considering whether an SPF update is needed.
