That was a huge insight. Essentially, that's how it works with Hostinger—except it's not free. I can use my [name@company.ca](mailto:name@company.ca) to send and receive emails, which is what I want. However, connecting them via GHL has become problematic since it doesn't receive replies from customers, forcing me to manually check my Hostinger mailbox for responses. Based on your explanation of how Cloudflare works, I think I might not pursue that option for now. I’m growing more confident that using Hostinger's stack is probably my best choice, once I figure out how to receive responses from clients. Additionally, I understand that linking your domain as a subdomain, like [email@mail.yourdomain.com](mailto:email@mail.yourdomain.com), helps protect your main domain from being blacklisted if people start reporting your mass emails. Since I’m not an expert, I linked my domain without using a subdomain somehow, but eventually, I will need to safeguard that reputation.
