How record calls through mail

I think you meant to ask "How to record calls through mail?"

Unfortunately, it's not possible to record calls through the mail. Recording a call requires a device or software that can capture the audio signal, which is not something that can be sent through the mail.

However, there are a few ways to record calls:

1. Phone recording apps: You can use a phone recording app on your smartphone to record calls. These apps can record both incoming and outgoing calls, and some even allow you to record calls automatically. Some popular phone recording apps include TapeACall, Call Recorder, and Automatic Call Recorder.
2. Landline phone recording devices: If you have a landline phone, you can use a phone recording device that connects to your phone line. These devices can record incoming and outgoing calls, and some even allow you to record calls automatically.
3. Computer-based recording software: You can use computer-based recording software to record calls made through your computer's speakers or microphone. This method is often used for conference calls or online meetings.
4. Cloud-based recording services: Some cloud-based services, such as Grasshopper or RingCentral, offer call recording features. These services allow you to record calls made through their platforms.

Remember to always check the laws and regulations in your country or region regarding call recording, as some jurisdictions may have specific requirements or restrictions.
