If you are using the Purchase API, you may also be sending receipts and shipping confirmations as transactional emails.

An existing customer could sign up, opt out of all emails, and then order a product. In these cases, use the following send_template parameter in your Purchase API calls. It will send the customer a receipt or shipment confirmation regardless of their opt-out level. In the rare case that a customer opts out of the confirmation template itself, further confirmations will not be sent, even with this parameter set.

1. Pass a purchase API call in post mode

Pass the <span class="c1 c3">send_template</span> parameter. The value is the name of the receipt or confirmation template you wish to send. Example (in JSON)

{"email":"mycustomer@gmail.com","items":[{"qty":1,"title":"T-shirt","price":1099,"id":"1234","url":"http://www.mydomain.com/product/tshirt"}],"send_template":"purchase receipt"}

2. Re-engagement for opted out users

The template should also include in the HTML an if/else statement that displays a re-engagment message if the user is opted out.{if profile.optout} Your purchase is on its way! We noticed you've opted out of email communications from us. We're sorry to see you go! Would you like to hear from us again? Click here to opt back in. {/if}

It should also link to a hosted user management/preference center page where the user can opt back in.

Note: If the user's email address status is 'hard-bounced,' the message will not be sent.
