I often hear people complain that their WordPress or WooCommerce sent emails go straight to spam. This is very common because, by default, WordPress relies on your hosting server to send emails. Hosting servers are made to host websites and are very seldom optimised for email sending.
Fortunately with just a few minutes effort you can get high reliability WordPress and WooCommerce email sending using Mailchimp Transactional Email. The instructions in the video show how to use a free WordPress plugin to get the reliable sending of Mailchimp for your contact form and eCommerce emails.
