Email Issue

Forgive me if this is not the right forum to post. Emails I send are now arriving as pages of code. I have WP Mail SMPT installed as well as Woocommerce and FunnelKit. I am using FunnelKit to customize emails going to customers, but this issue was happening before activating FunnelKit. In the Woocommerce settings under the Email tab, the various emails are set to HTML, but in all honesty I am unclear as to whether these setting have any effect on the emails being sent if I am using FunnelKit to automate and send such emails. Any help and light shed on this so I have a better understanding is greatly appreciated.
