What is Transport Layer Security (TLS) and why is it important?

TLS encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence.

APSIS One requires at least TLS encryption 1.2.

TLS encryption is basically a cryptographic protocol that provides end-to-end security of data sent between applications over the Internet.

  • For emails sent through APSIS One Marketing Automation tool and Transactional email forced TLS encryption is the default standard since they are considered personal emails.

  • Sending done through the Email tool have TLS encryption as the default standard. But if the recipient mail server doesnt support TLS encryption, then the mail will be delivered unencrypted. If you dont want the mail to be delivered unencrypted, you can request that all your sendings are sent through channels (specific mail server accounts) that are configured to require TLS encryption - making the TLS encryption forced.

If you wish to enable forced TLS encryption for all types of sending, please reach out to our Support Team and they will help you set it up. If you decide to, it will cover all sections in your APSIS One account.

The impact of enabling forced TLS encryption

When enabling forced TLS encryption mails are sent through channels - specific mail server accounts - that are configured to require TLS encryption. If the recipient mail server does not support encryption, the connection is dropped, and the mail is discarded - meaning you might experience slightly higher bounce rates.

Note: In some jurisdictions the GDPR regulations call for a higher level of security when you send emails. Make sure to investigate regulations for your local jurisdictions.
