Why are my Shopify store notification emails going straight to spam?

Shopify notification emails land in spam when your domain lacks SPF and DKIM authentication records, causing receiving servers (like Gmail and Yahoo) to flag Shopify’s mail servers as unauthorized senders.

“This is almost always missing SPF and DKIM authentication, so Gmail and Yahoo have no way to confirm your emails are legitimate. I’ll get your domain properly authenticated within 24 hours for $99.”
