Email Messages

Back in Stock can send three kinds of customer email. Each one serves a different part of the sign-up and notification process, so stores can enable the messages that suit them.

Confirmation Messages

A confirmation acknowledges that an immediately active subscription was created. It does not ask the customer to take another action and does not mean the product is available.

Enable Confirmation Email when customers should receive a receipt for joining the waiting list. If email verification is required, the verification message is sent instead.

Verification Messages

A verification message contains a signed link that activates a pending subscription. Until the customer follows that link, the request is not eligible for an availability notification.

The verification link remains valid for the configured verification window. Its message should make the required action and expiry clear without implying that stock has been reserved.

Availability Messages

An availability message is sent after a variant becomes available and the subscription is selected for notification. It identifies the exact Commerce variant and directs the customer back to the product.

Back in Stock records a message as sent when Craft’s mailer accepts it. This does not confirm that the email reached the inbox, was opened, or led to a purchase. Notification Activity explains the sending results kept by the plugin.

Editing Message Content

The default confirmation, verification, and availability content is managed through Utilities → System Messages. This is the usual place to edit subjects and message bodies, including localised content for a multisite project. The message keys are back_in_stock_confirmation, back_in_stock_verification and back_in_stock_available.

Projects that need complete control over the HTML can configure a site Twig template for confirmation or availability messages. A custom template replaces the corresponding System Message body and receives the subscribed variant, subscription, decoded options, signed cancelUrl, and rendered subject. Verification remains a System Message and also receives its signed verifyUrl.

Sites upgraded from Back in Stock 4.1 keep sending the plugin’s bundled templates with their saved subjects. Clear the template fields on the Email page to switch to System Messages.

Sender name and address can be set on the plugin’s Email page. When left empty, the plugin uses Craft’s system email settings.
