Order Confirmation Emails Are Sent Twice

Mex — Fri, 09 Oct 2026 13:45:46 +0000

There is a confirmed issue in some Magento 2 versions: an order is placed successfully, but the customer receives two order confirmations for the same order. The cause is not necessarily the mail server, SMTP module or custom sending logic.

Adobe has confirmed a Magento core issue. A patch is available through the current Quality Patches Tool 1.1.84 under the identifier ACP2E-5059 .

According to Adobe, the affected versions include Magento Open Source and Adobe Commerce from 2.4.8 through 2.4.9. Customers may receive duplicate order confirmation emails for a single purchase.

If you encounter this in a current Magento store, do not start by rebuilding your entire mail configuration. Depending on the version, it may simply be this known core issue.

The patch ACP2E-5059 can fix the issue without waiting for a full Magento upgrade.

If your store sends duplicate order confirmations, I can check whether this patch applies or another issue is responsible.

Fixing Incorrect authentication data

You or your customers may encounter the message Incorrect authentication data in various places in Magento 2, both on the storefront and in the admin area.

You are probably sending mail through SMTP, and the saved authentication details are incorrect or outdated. Check and correct the SMTP credentials. That should resolve the issue.

Contact form message content appears as a single line

Mex — Thu, 02 Sep 2021 09:20:10 +0000

Are comments submitted through the Magento 2 contact form displayed as a single line, losing the sender’s line breaks? A small change to your email template can solve that.

Change the following line in your email template:

{{var data.comment}}

{{var data.comment|nl2br}}

Formatted messages should now display correctly.

Changing customer email addresses in Magento

When testing new features locally on your development machine, it is advisable to change the customers’ email addresses. You can use the following script for this purpose:

Warning: Never execute these statements on a production system!

update sales_flat_quote set customer_email = (concat(substring(md5(rand()) from 1 for 20), '@example.com'));
update sales_flat_order set customer_email = (concat(substring(md5(rand()) from 1 for 20), '@example.com'));
update sales_flat_quote_address set email = (concat(substring(md5(rand()) from 1 for 20), '@example.com'));
update customer_entity set email = (concat(substring(md5(rand()) from 1 for 20), '@example.com'));

Now open an order, for example, and check that the email address has been replaced.

Changing Magento store email addresses in a local installation

Warning: Never execute these statements on a production system!

The following query generates an update script according to a pattern you define. In this example the pattern is “your-domain.com”. Replace it with your own domain.

select concat('update core_config_data set value = \'test@example.com\' where path = \'', path, '\';')
  from core_config_data where value like '%@ihre-domain.de%'

The resulting script might look like this:

update core_config_data set value = 'test@example.com' where path = 'general/imprint/email';
update core_config_data set value = 'test@example.com' where path = 'sitemap/generate/error_email';
update core_config_data set value = 'test@example.com' where path = 'sales_email/order/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/order_comment/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/invoice/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/invoice_comment/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/shipment/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/shipment_comment/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/creditmemo/copy_to';
update core_config_data set value = 'test@example.com' where path = 'sales_email/creditmemo_comment/copy_to';
update core_config_data set value = 'test@example.com' where path = 'trans_email/ident_general/email';
update core_config_data set value = 'test@example.com' where path = 'trans_email/ident_sales/email';
update core_config_data set value = 'test@example.com' where path = 'trans_email/ident_support/email';
update core_config_data set value = 'test@example.com' where path = 'trans_email/ident_custom1/email';
update core_config_data set value = 'test@example.com' where path = 'trans_email/ident_custom2/email';
update core_config_data set value = 'test@example.com' where path = 'contacts/email/recipient_email';
update core_config_data set value = 'test@example.com' where path = 'paypal/general/business_account';
update core_config_data set value = 'test@example.com' where path = 'samples/email/recipient_email';
update core_config_data set value = 'test@example.com' where path = 'bewertung/email/recipient_email';
