I added DNS records on cloudflare and upon checking DNS, all turned out OK.

I'm currently using WP Mail SMTP plugin on my wordpress website and have added Emailit as the mailer. Email delivery is working upon testing, but I also got below error from the plugin.

"Action Needed: It doesn't look like the SPF record required by your SMTP server has been added to your domain. Please contact your SMTP server provider for details on how to find the SPF record, and how to add this record to your domain's DNS."

"The test email might have sent, but its deliverability should be improved."

Is this something that can be ignored, or is there something I could fix?
