Setting up marketing automation

In just a click, you can enable Marketing Automation on your website and track your contacts' activity on your website. This is very easy to do: check the "Activate marketing automation through SendinBlue" and click on the Save button at the top right.

Once Marketing Automation is enabled and functioning properly, you will find these logs in your SendinBlue account under Automation > Logs > Event logs:

  • page
  • identify
  • track events


Note that the plugin uses the RESTful implementation. For this reason, the tracking ID status on the Tracking code page will not show as verified.

2. Creating an abandoned cart workflow

The plugin automatically creates 3 track events that can be used to create an abandoned cart automation workflow:

  • cart_created is passed when an item is added to the cart by an identified contact. When the cart is updated, updated data will be passed in this event as well.
  • cart_deleted is passed when a cart is emptied
  • order_completed is passed when the order has been made

Configuring transactional emails

Go to the Transactional Emails tab to set up your transactional emails.

1. Sending transactional emails

Selecting "Yes" to activate SendinBlue SMTP, your transactional emails (order confirmations, password resets, etc.) will be sent via the SendinBlue SMTP. Your password can be found in your SendinBlue account, under the SMTP tab. You must make sure that your SMTP account has been activated.


You can send a test email thanks to the field "Send email test From/To". This test email will appear in the transactional logs of your SendinBlue account.


2. Setting up email confirmation emails

To use a SendinBlue template for your confirmation emails, you have to make sure that emails are sent through SendinBlue SMTP.

To welcome your new subscribers, you have 3 options.


  1. No confirmation > With this option, subscribers will be added to the list(s) you've selected under the Contacts Manager tab without any confirmation email.
  2. Simple confirmation > With this option, subscribers will be added to the list(s) you've selected and will receive a confirmation email. Select a SendinBlue template in the dropdown list.
  3. Double opt-in confirmation > With this option, subscribers will be added to the list(s) you've selected and will receive a confirmation email. Select a SendinBlue template in the dropdown list. Check the "Send a final confirmation email" box if you want to send another email after a new subscriber has clicked on the confirmation email. We recommend using a double opt-in form.

If you want to redirect your contact to a landing page or your website, check the "Redirect URL after clicking in the validation email" box. If you want to redirect to a landing page created on SendinBlue, paste the URL you get after publishing your landing page.

3. Setting up notification emails

You can override OpenCart notification templates with SendinBlue templates. Note that it is not possible to personalize the templates with variables such as order number, order price, shipping status etc. Below is the list of notifications that can be overridden.

  • Canceled
  • Canceled Reversal
  • Chargeback
  • Complete
  • Denied
  • Expired
  • Failed
