At Assette, the security and privacy of our clients’ information are of paramount importance. To ensure that all email communications are secure, Assette utilizes Transport Layer Security (TLS) encryption provided by the third-party service SendGrid for all emails sent from our platform. This article explains how Assette leverages TLS encryption via SendGrid to protect email communications, the benefits of this approach, and what it means for our users.
What is TLS Email Encryption? #
Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. When applied to email, TLS encryption ensures that the connection between email servers is secure, preventing unauthorized access and interception of email content during transmission.
How TLS Works in Email Communication #
- Establishing a Secure Connection: When an email is sent, TLS initiates a handshake between the sending and receiving email servers to establish a secure, encrypted connection.
- Encryption: The email content is encrypted during transit, making it unreadable to anyone who might intercept it.
- Decryption: The receiving server decrypts the email so it can be delivered to the recipient’s inbox securely.

How Assette Uses TLS Encryption via SendGrid #
Secure Email Transmission #
All emails sent from Assette’s platform are routed through SendGrid’s servers, which support TLS encryption. This means:
- Automatic Encryption: Emails are automatically encrypted during transmission if the recipient’s email server also supports TLS.
- Downgrade Protection: If the recipient’s server does not support TLS, SendGrid ensures that the email is sent over a secure connection whenever possible and follows best practices to protect the email content.
Frequently Asked Questions #
Do I Need to Do Anything to Enable TLS Encryption? #
No action is required on your part. TLS encryption is automatically applied to all outgoing emails from Assette when sent to email servers that support TLS.
What If My Email Provider Does Not Support TLS? #
If your email provider does not support TLS, SendGrid will attempt to deliver the email over a secure connection using the next best method.
Is the Content of the Emails Encrypted at Rest? #
TLS encryption secures the email content during transmission. For encryption at rest (when the data is stored), Assette employs additional security measures within our platform and complies with data protection regulations.
