To keep WooCommerce emails out of spam, send mail through authenticated domains. Set up SPF and DKIM records, and add DMARC with a monitoring policy. Use a dedicated SMTP provider (SendGrid, Mailgun, Amazon SES, etc.) instead of PHP mail, and verify your “From” address matches the domain. Avoid spammy subject lines, excessive caps, and too many links. Include your business address and unsubscribe/notification preferences where appropriate. Keep templates clean, mostly text with one logo image, and test with mail-tester. Warm up new domains/IPs gradually, and monitor bounces and complaints. Also ensure your server has rDNS, TLS, and consistent sending volume.
