Test email sending from my app (offline)


All I’m trying to achieve is test (preview) the emails sent out by the Wordpress/Woocommerce app.

Is there any sort of email catcher or email previewer I could use ?

The solutions presented in this thread: How can I send email from my app? are paid (SendGrid and Mandrill) and this Google Compute Engine One seems too complicated and not sure if paid or not either

Please advice
