Telegram is fine for a single-user setup or for a small team. If you need better multi-user and multi-channel support, you can use Slack.

Both have an easy to use bot API and both support adding action buttons to messages that you can connect to your app's webhooks.

Using a messenger, in my experience, feels more convenient than using an email client when dealing with automations. You can view messages by channel, you don't have to deal with GMail assigning random categories to your emails, and the UI is faster.
