Shopify Sender Email Rewritten to shopifyemail: Causes and Fixes

Quick Answer: Why Shopify Rewrites Your Sender Email

If your customer notification emails display a fallback sender address such as store+123@shopifyemail.com instead of your custom domain, or if your store's messages land directly in spam folders, your domain fails authentication checks. Modern mail providers like Gmail and Yahoo enforce strict sender guidelines requiring domain authentication and DMARC policies.

To fix this issue, you must authenticate your custom domain inside the Shopify Admin by adding 4 CNAME records to your domain's DNS manager (which configures DKIM and SPF verification) and adding a valid DMARC TXT record with at least v=DMARC1; p=none;. Once DNS changes propagate, Shopify stops rewriting your sender address.

Symptoms of Email Rewriting and Deliverability Problems

Shopify store owners typically encounter this issue through the following behavior:

  • Sender Email Substitution: Test order notifications or customer emails display an unwanted address like store+1029384@shopifyemail.com in the recipient's inbox.
  • High Spam Landing Rate: Store notification emails arrive in customer spam or junk folders instead of the primary inbox.
  • Shopify Admin Warning: A banner or notice appears in your Shopify Admin under Settings > Notifications indicating that your domain needs authentication.
  • Bounced Messages: Transactional emails fail to reach subscribers using major webmail services.

Primary Causes of Shopify Email Rewriting

Understanding why Shopify changes your outgoing email address helps prevent recurring configuration issues.

1. Unauthenticated Custom Domain

When you enter a custom sender email address (e.g., info@yourdomain.com) without verifying ownership, third-party mail servers treat outgoing messages as unauthorized. To protect your domain reputation and prevent impersonation, Shopify automatically rewrites the outgoing "From" address to their fallback domain (shopifyemail.com).

2. Missing or Misconfigured DMARC Record

Major inbox providers require a valid DMARC (Domain-based Message Authentication, Reporting, and Conformance) record. If your custom domain lacks a DMARC TXT record, Shopify enforces the fallback address to ensure delivery standards are met.

3. Using a Free Email Address

If your store's sender address uses a free webmail service like @gmail.com or @yahoo.com, you cannot authenticate ownership through custom DNS records. Shopify will always rewrite free email addresses to a shopifyemail.com fallback format.

4. Conflicting or Invalid DNS Records

Several common DNS setup mistakes can break verification:

  • Multiple DMARC Records: Publishing more than one DMARC TXT record on a single domain invalidates DMARC evaluation entirely across all services.
  • Strict Alignment Tags: Setting strict alignment tags like adkim=s or aspf=s in your DMARC record prevents Shopify's sender verification from passing.
  • DNS Propagation Delay: CNAME and TXT changes take time to update across global DNS networks.

Step-by-Step Fix: Authenticate Your Sender Domain in Shopify

Follow these steps to authenticate your custom domain and restore your custom sender email address.

Step 1: Check Your Sender Email Format

In your Shopify Admin, navigate to Settings > Notifications. Verify that your sender email address uses a domain you own (such as support@yourdomain.com). If you are using a free address ending in @gmail.com or @yahoo.com, change it to a branded email address on your custom domain before proceeding.

Step 2: Generate Shopify CNAME Records

  1. Go to Settings > Notifications in Shopify Admin.
  2. Locate the Sender email section and click Authenticate your domain.
  3. Shopify will generate 4 distinct CNAME records. Keep this window open or copy the Host Name and Value pairs provided.

Step 3: Add CNAME Records to Your DNS Provider

Log in to your domain registrar or DNS host (such as Cloudflare, Namecheap, or GoDaddy). Navigate to your domain's DNS management page.

  • Add each of the 4 CNAME records provided by Shopify.
  • Ensure the host names (or Name fields) and values match the entries generated in your Shopify Admin.
  • If your DNS provider uses proxy settings (such as Cloudflare's orange cloud), set these specific CNAME records to DNS Only (unproxied).

Caution: Be careful not to alter or delete existing MX records or business email TXT records, as doing so will disrupt your regular corporate email hosting.

Step 4: Create a Valid DMARC Record

Check your DNS manager to see if a TXT record for _dmarc already exists. If no DMARC record exists, create one with the following values:

  • Type: TXT
  • Name/Host: _dmarc (or _dmarc.yourdomain.com depending on your host)
  • Value/Content: v=DMARC1; p=none;

If a DMARC record already exists, do not create a second one. Instead, edit the existing record. Ensure it does not include strict alignment tags (such as adkim=s or aspf=s), which will cause Shopify domain verification to fail. Maintain relaxed alignment (adkim=r and aspf=r, or omit those tags to use defaults).

Caution: Creating multiple DMARC TXT records on a single domain invalidates DMARC checking. Furthermore, setting your DMARC policy to p=reject or p=quarantine before all legitimate sending channels are aligned can cause your valid business emails to bounce or land in spam folders.

Step 5: Verify Status and Allow DNS Propagation

After adding the 4 CNAME records and the DMARC TXT record, return to Settings > Notifications in your Shopify Admin and click Authenticate domain.

DNS record updates take time to spread across the internet. While changes often take effect in a few hours, full DNS propagation can take up to 24 to 48 hours. If Shopify shows a pending or failed status immediately after saving DNS records, wait several hours and check the status again.

Verification

Once domain authentication succeeds, confirm your setup is functioning correctly:

  1. Verify that the status banner in Shopify Admin under Settings > Notifications shows as Authenticated.
  2. Place a test order or send a test customer notification from your store.
  3. Inspect the incoming email headers or the "From" line in your email client. The email should display your custom sender address (e.g., orders@yourdomain.com) without any shopifyemail.com substitution.

Frequently Asked Questions

Why did Shopify start rewriting my email address automatically?

Shopify introduced automatic sender address rewriting to comply with strict anti-spam requirements established by major email providers like Google and Yahoo. If a store sends emails from an unauthenticated custom domain, receiving servers may mark the messages as spam or reject them entirely. Rewriting the address to a verified fallback domain ensures the message is delivered.

Can I use my personal @gmail.com or @yahoo.com address as my Shopify sender email?

No. Free email services do not allow you to configure custom DNS authentication records. If you enter a free public email address as your sender address, Shopify automatically rewrites it to the shopifyemail.com fallback format. You must use a custom domain name to display your own email address.

How long does domain authentication take in Shopify Admin?

Once CNAME and DMARC records are added to your DNS manager, verification can complete within a few minutes to a few hours. However, standard DNS propagation can take up to 24-48 hours depending on your DNS host and record TTL settings.
