Cortex does not handle transactional emails at this time. However we can integrate your transactional emails with SendGrid using your ReSci account and e-commerce software.
Need to send transactional emails such as an immediate welcome email after a couple minutes of sign up or shipping confirmation notice? You can do so with the same SendGrid user that is connected via Retention Science.
Get started with their documentation to integrate with SendGrid.
Check out the Magento SendGrid Aschroder SMTP Extension on Magento Connect.
You can also find detailed installation instructions from SendGrid's documentation.
To send email through SendGrid using WordPress we recommend the Official SendGrid WordPress Plugin. To install, use the WordPress admin panel or follow these instructions. Once installed, click on the Settings link for the plugin on your plugins page, enter your SendGrid username and password, and you’ll be ready to go!
