    I got this email from my sendgrid account and since I use this plugin and a few others to work with the API I was wondering what version of TLS you are using with your plugin to know if any action needs to be taken on my part to get switched to TLS 1.2 or newer.

    Twilio SendGrid will be deprecating its support for TLS Versions 1.0 and 1.1. After April 20, 2023, any mail sent using these TLS versions will fail to send.

    Thank you.

    Hello @jhanten,

    TLS is an authentication encryption mechanism when used in Fluent SMTP. The email delivery provider is actually responsible for the exact version of the TLS

    More specifically Fluent SMTP use TLS over HTTP as RFC 2818

    The hosting you use and the version enabled will be effective and most the versions are now TLS 1.3 for popular web hostings and control panels

    Thank you
