Finally, No More Spam Folder Issues with PHP Mail!
As a freelance web developer working with a marketing agency, I need to set up SMTP for every website I build. However, my clients aren't always ready to provide SMTP credentials, which forces me to fall back on PHP mail — and that almost always ends up sending emails straight to the spam folder. This plugin completely solved that problem. I can now use PHP Mail instead, and it works perfectly. Honestly, this is a game-changer for my workflow.
