One finding blocks deliverability.
ywaozhuo.com publishes an enforcing DMARC policy, so mail that forges its domain is quarantined or rejected at the recipient.
Your domain does not currently have a valid SPF record, so receiving mail servers can’t verify which services are allowed to send email for your site. This matters because it can increase the chance that your messages land in spam or that attackers can more easily spoof your address. The fix is to add or correct the SPF setting in DNS so it lists the email services you actually use to send mail.
One send: the full report — every finding and fix — lands in your inbox, with a free account waiting. Opening it signs you in and starts a 14-day Monitor trial. No card, and you can unsubscribe in one click.
