Q&A for How to Send An Anonymous Email

VPN means Virtual Private Network. It changes your IP so that it looks like you're located someplace else to anyone monitoring your internet use.

VPNs are weak security. One can trace down a VPN easily by using a name server lookup of the proxy's out-facing IP, which will come back to the VPN provider. VPNs also log their customer's IP addresses, and are not anonymous. However, most of them will lie about this. Tor, by contrast, is a "public" VPN of sorts, with encryption in place, in such a way that prevents the outbound facing servers from ever knowing your true IP.

Establish a temporary free email account (through Yahoo, Gmail, Hotmail, etc.) and send the email from there. You never have to use that account again.

All apps are accessible using a VPN. The only restrictions are that some websites (especially payment providers) block or flag known public VPN IPs in order to prevent fraud.

Yes. All devices connected to the Internet (computers, notebooks, phones, tablets, wireless printers, etc.) are assigned an IP address by the router/cable modem.

You just have to choose your VPN provider (carefully) based on your preferences and their privacy policies. Then, you can just set it up on your device following their instructions.

If you mean using an existing email account of your own, then yes! You might have to change the settings to ensure that it looks like the message is being sent from a different person, though. If it's someone else's existing account, then you'd have to know the password.
