Answer 1

Yes, you need to execute sendmail through the for loop:

for /f "tokens=*" %%a in ('[sendmail command line]') do (
    set VAR=%%a
)

After this runs, VAR will be set to the last line that sendmail output. You can then do processing on that line

for /f "tokens=5,* delims= " %%a in (%VAR%) do (
    if "%%b"=="Email was sent successfully!" (
        echo SUCCESS
        exit /b 0
    ) else (
        echo FAILURE
        exit /b 1
    )
)

Answer 2

normally, you just use the for loop to capture the output. see here notes 4. (and search internet for more)
