We are using Slack as a team. However, there are also parties that are not part of our team but can participate via a mailing list.
I want to set up a channel in Slack, say #mailinglist. Whenever some team member posts a message into this channel I want an email going out to the mailinglist address.
I solved this by using Slack's WebHook integration and let it call a little PHP script I wrote. The script takes the information and mails it.
The script is really simple and it's on GitHub.
/mail This is the email body or can the mail script be triggered automatically by a keyword in a post?
There's a Slack integration for that: MailClark. It includes a Group mode, which does exactly what you describe. You can have a Slack channel with any combination of Slack and email users, where Slack messages are sent out as emails, and emails are received as Slack messages.
This was asked quite some time ago and I think the answers are not accurate anymore. MailClark will put the plug end of 2022 and not sure if the php example is still working.
But I ended checking what's the latest desire for slack how to tackle such a problem and I guess it is a Slack Bolt App: https://api.slack.com/bolt
I can recommend it.
It is surprisingly easy to do a simple text matching that can e.g. reverse your text. So "hello" becomes ""olleh".
E.g. here in Javascript.
// Reverse all messages the app can hear
app.message(async ({ message, say }) => {
// Filter out message events with subtypes (see https://api.slack.com/events/message)
if (message.subtype === undefined || message.subtype === 'bot_message') {
const reversedText = [...message.text].reverse().join("");
await say(reversedText);
}
});
I guess from there it is easy to instead send the text as email (check sendgrid, mailgun, amazon SES) or start a Falcon 9 Rocket.
