## gmailで指定のチャンネルのログを流す
スプレッドシートからメール文面を作成し、送信処理を行う

```javascript:send_mail.gas
// Configuration: Obtain Slack web API token at https://api.slack.com/web
var API_TOKEN = PropertiesService.getScriptProperties().getProperty('slack_api_token');
var FOLDER_NAME = 'Slack Logs';

// メール送信先
var mail_to = [
  "hogehoge@gmail.com",
  "fugafuga@gmail.com"
];

var dObj = new Date();
dObj.setDate(0);

// ここでシートを指定する
var sheetName = "no-name-sheet (C2SDE2D2)";
var body=sheetName+"のaログ\n\n";

## 感想
もっときれいに整形できるはず
無料枠の限界を感じる
