add to your app config files something like this

{lager, [
    {handlers, [
        {lager_sendmail_backend, [
            {level, error},
            {from, "lager_sendmail_backend <from@example.com>"},
            {to, ["errors@example.com"]},
            {subject, "erlang errors in my app"},
            {aggregate_interval, 600000}, % aggregation interval (10 minutes by default)
            {msg_limit, 20}, % messages per letter. thats default
            {sendmail_cmd, "/usr/sbin/sendmail -t"} % cmd to send email. thats default. use "cat > bla" for debug
        ]},
        {lager_sendmail_backend, [
            {level, warning},
            {from, "lager_sendmail_backend <from@example.com>"},
            {to, ["warnings@example.com"]},
            {subject, "erlang warnings in my app"}
        ]}
    ]}
]}

unfortunately, you cannot use one instance of backend for both warnings and errors for now...
