Email encryption in transit
S/MIME is used to support enhanced encryption in transit, and automatically encrypts your outgoing emails if it can.
Important: These steps only work if you have S/MIME enabled on your account.
Check if a message you’re sending is encrypted
- Start composing a message.
- Add recipients to the “To” field.
- To the right of your recipients, you’ll see a lock icon that shows the level of encryption that is supported by your message’s recipients. If there are multiple users with various encryption levels, the icon will show the lowest encryption status.
- To change your S/MIME settings or learn more about your recipient’s level of encryption, click the lock, then View details.
Check if a message you received is encrypted
- Open a message.
- On an Android device: Tap View details
View security details.
On an iPhone or iPad: Tap View details. - You’ll see a colored lock icon that shows you what level of encryption was used to send the message.
What the encryption icons mean
When you’re sending or receiving messages, you can see the level of encryption a message has. The color of the icon will change based on the level of encryption.
- Green (S/MIME enhanced encryption)
. Suitable for your most sensitive information. S/MIME encrypts all outgoing messages if we have the recipient’s public key. Only the recipient with the corresponding private key can decrypt this message.
- Gray (TLS – standard encryption)
. Suitable for most messages. TLS (Transport Layer Security) is used for messages exchanged with other email services who don’t support S/MIME.
Tip: TLS support is not guaranteed. Support is inferred from past communications with the email service. - Red (no encryption)
. Unencrypted mail which is not secure. Past messages sent to the recipient’s domain are used to predict whether the message you’re sending won’t be reliably encrypted.
I see the red lock icon
If you’re writing a message and see the red lock icon, consider removing these addresses or deleting the confidential information. To see which address is unencrypted, click View Details.
If you received a message with the red lock icon and the message contained particularly sensitive content, let the sender know and they can contact their email service provider.

great I just learned about this translating things that you neednt translate and getting something out of them and here I need to do it and cannot compute maybe because of exhaustion
