What is SPF Email?

Define Sender Policy Framework:

What is SPF? Email SPF as mentioned under RFC 7208 is an email authentication standard that protects organizations against impersonation. The biggest threat to your customer’s email security is an attacker using your brand name and domain to send fake messages. Phishing emails like these can be convincing enough that your customers won’t know the difference — and end up falling prey to a scam. This can damage both your brand image and your reputation with email providers, making it less likely that your actual emails reach customer inboxes.
