Now that you've successfully generated your SPF record, complete the setup by creating a TXT record for your domain. The process will be similar for most domain registrars and hosting providers with some small differences.
Here is an example SPF record to guide you.

An SPF record is a type of DNS record that stands for Sender Policy Framework. It is used to help prevent email spam by verifying that the sender of an email message is authorized to send email from the domain name that appears in the message's "From" field.
The way it works is by listing the authorized mail servers for a domain in the SPF record. When an email message is received, the recipient's mail server can check the SPF record for the sender's domain to see if the sending mail server is authorized to send email on behalf of that domain. If the sending mail server is not listed in the SPF record or is not authorized, the email can be marked as spam or rejected altogether.
Having a properly configured SPF record is important because it can help protect your domain and your email recipients from email spoofing and phishing attacks. It can also help improve email deliverability by reducing the likelihood that your legitimate emails will be marked as spam or rejected by recipient mail servers.
