Hey there,
I am currently creating an opencart site for my ecommerce business and I am worried about customers receiving emails correctly. The final stages of the checkout sends some important information to the buyer and I want them to receive it no matter what. I am using a secure HTTPS server but I am still testing on localhost at the moment.
What I want to know is, are all emails sent via HTTPS guaranteed to pass the customer’s spam filter and arrive in the inbox?
thanks
No.
Mail never gets sent via HTTPS no matter what you do as that is a web format for passing web page data between the browser and the server only.
Even when you apply mail security certificates to the email (one from the sender and one from the receiver) it only allows you to encrypt the email so no one can intercept it. Since it needs the recipient’s public key to do the encryption it requires prior exchanges of email to get it and so you’d at least know that the recipient doesn’t have the sender email address blacklisted.
