How do I attach a file to an email?
If the file is saved in your Slack workspace:
Use the ‘Attach a file’ function which come with the message preview.
If you'd like to upload a file from your computer/mobile.
- Both in a channel or in a thread, use the ➕ sign or simply Drag & Drop your file.
- From the email preview, you'll have another chance to attach a file.
