Can I send my eLearnCommerce email notifications using the email service of my choice?
The answer is yes!
If you'd like to have your eLearnCommerce email notifications sent out using an external service, you can easily accomplish that with a plugin like wpMandrill or any other SMTP service.
If you choose to use wpMandrill, just install it and then go to Settings -> Mandrill in your WordPress installation to configure the plugin.
Once configured, it replaces the wp_mail function included with WordPress and allows you to use the Mandrill API to send outgoing emails.
If you have a different SMTP service of choice, you just need to follow the same process to get it installed and configured on your WordPress installation. Once you've done that, your eLearnCommerce email notifications will be sent out using your preferred service.
