Thunderbird for MacOS X 10.11
El Capitan (MacOS X 10.11) is not listed in https://www.mozilla.org/en-US/thunderbird/38.3.0/system-requirements/
There are warnings for installing El Capitan if important programs will not work on the new system. When will El Capitan be supported?

Give it a try. It will most likely work just fine.
