We can imagine that having website enquiries coming from info@rocketspark can sometimes be frustrating. However, we can't change the from address to be the enquirer's email. There is a strong rationale for this:
- The email was not sent by that person, it was actually sent by your website, which is on the Rocketspark servers.
- If we set the from address as the customer's email address instead of an @rocketspark email address, your email programs (Outlook, Google+) can detect that the domain of the from address does not match the server it was sent from and would likely block it as spam a good amount of the time, which would mean lost enquiries for you.
- The reason these email programs do this is that this is how scammers appear to email you from trusted companies like banks, paypal, google etc. They make it appear like the email has come from a legitimate source because the from address says so, when in reality the scammer's web server is just creating an illusion.
