Shopify changes sender email addresses to protect its ecosystem from abuse, enhance deliverability, and combat phishing and spam, complying with evolving ESP and Yahoogle policies. This occurs when domains aren't properly authenticated, harming sender reputation. To resolve this, users must correctly configure SPF, DKIM, and DMARC records in their DNS settings, authenticating their domain and authorizing Shopify to send emails on their behalf. This ensures emails reach recipients' inboxes, builds trust with email providers, and improves overall email deliverability. Failure to do so results in Shopify reverting to its generic sender email.

Shopify changed sender email addresses due to an increased focus on deliverability and security. Unauthenticated domains harm sender reputation and increase the risk of phishing attacks, prompting Shopify to enforce authentication. To prevent this, users should configure SPF, DKIM, and DMARC records in their domain's DNS settings, which validates the sender and improves email deliverability.

Shopify's change in sender email addresses is primarily driven by the need to protect its platform from abuse, enhance deliverability, and comply with emerging email standards. This includes Yahoogle updates and ESP policies. More stringent authentication policies combat phishing and spam. Authentication, which involves setting up SPF, DKIM, and DMARC records, is key to resolving the issue and ensuring emails reach recipients reliably. Using a custom branded domain will affect this too.

Shopify changes the sender email address if the domain is unauthenticated to protect against phishing and spam. Authentication involves adding SPF and DKIM records (and DMARC for a more robust policy) to your domain's DNS settings. These records verify the sender's identity, authorize Shopify to send emails on your behalf, and improve email deliverability by preventing emails from being flagged as spam or identified as forged.
