DocuSign is deprecating support for outbound TLS 1.0 on 31st October 2021. Although DocuSign has not supported TLS 1.0 in our products since 2018, we did allow opportunistic TLS which means if a recipient's email server did not accept a higher version of TLS, they could receive emails via TLS 1.0. This will end on October 31st.

Additional information can be found on the DocuSign Support Center.

Please contact Technical Support if you have any questions.
