📥Receiving Email:

6 main items to consider in verifying email sender’s origin, and if email is suspected of scam

1. Email protocol info (eg. SMTP): Verifies email’s source and country
2. Past conversations’ contact parties: Verifies if past conversations are not forged or disguised as original sender
3. Mail server’s source country: Verifies if the sender's email server is not from an unrelated country
4. Sender domain registration information: Verifies if info on registration matches contact’s
5. Domain’s website screenshots: Verifies if webpages/sites appear legitimate
6. Verify email by comparison (if stored by sender): Verifies email content’s originality, highlighting any differences

📤Sending Email:

Different ways of handling messages, meeting your distinct needs

1. Preserve on blockchain: Sensitive emails kept as proof, valuable for future court case defense. Email's digital fingerprint is permanently stored on blockchain and its timestamp is recorded.
2. Encrypt email content: Prevents sensitive information leaks while in transit. Email can first be encrypted by assigning it a password, before being sent out.
3. Supports everyday emails: Can still send/receive emails as normal, after tool added on
4. Add on & use instantly: Businesses can automatically deploy to their employees’ devices (G Suite required)

ChkSender helps users validate email integrity by verifying sender's domain information.
This version supports Gmail, and will support other Webmail service soon.
