Migma for Slack is in beta and rolling out. Some workspaces may not have access yet.

​
Before you start

You need:
  • A Migma account
  • Permission to install apps in your Slack workspace
  • A Slack workspace where you can invite and mention apps
The Migma app is installed once per workspace. Each teammate links their own Migma account before using it.

​
Connect Migma in five steps

1

Open the Slack integration

In Migma, open Settings → Integrations, find Slack under Chat, then select it.You can also add Migma to Slack directly.

2

Choose a workspace and approve access

Select the correct Slack workspace, review the requested permissions, then select Allow.Migma needs access to read messages that mention the bot, reply in threads, and upload preview files. If your workspace restricts app installations, a Slack owner may need to approve it first.

Return to Slack and send the request again

Return to the channel and mention @Migma again. The request that opened the connection flow is not resumed automatically.Migma replies in a thread with its result. Use Open in Migma to continue editing, download HTML, or prepare the draft for sending.

​
What the connection allows

The Slack connection does not include email-send access. Sending, exporting, and final approval stay in Migma.
Migma processes messages that mention the bot. Unrelated channel messages are not sent into the Migma reply flow.

​
What you can ask

Talk to Migma in plain language: You can also attach a screenshot and say @Migma make an email like this for Stripe.

​
Channels, threads, and brands

  • Mention @Migma for each new request.
  • Keep follow-up edits in the same thread so Migma has the right context.
  • Invite Migma to a private channel before mentioning it there.
  • Name another brand or paste its website when you want to switch brands.
When you name a brand, Migma checks your existing brands first. If none match, it asks for a website and imports it.

​
Disconnect

Say @Migma disconnect, or revoke the key named for your Slack workspace under Migma Settings → Developers → API Keys. After disconnecting, Migma asks you to link your account again on your next mention.

​
Troubleshooting

​
I cannot install the app

Your Slack workspace may require owner approval. Ask a workspace owner to approve Migma, then restart the install. See Slack’s guide to adding apps.

​
Migma does not reply

Check that:
  • Migma is installed in the current workspace.
  • Migma is a member of the channel.
  • Your message includes the exact @Migma mention.
  • You are testing in a thread or channel where apps can post.

​
The Connect Migma button does not appear again

The bot limits repeated connection prompts. Wait up to one hour, then mention @Migma again.

​
I linked my account, but my request did not run

Return to Slack and send the mention again. The original connection request is not resumed after linking. Disconnect, link again, then retry the mention. If the problem continues, contact Migma support with your Slack workspace name and approximate time of the failed request.
