@Migma in any channel to create and edit branded emails. The bot replies in the thread with preview images and, when you ask, HTML files.
Migma for Slack is in beta and rolling out. Some workspaces may not see it yet.
Set up
1
Add the app
In Migma, open Settings → Integrations → Slack and click Add to Slack. Approve the workspace permissions. Any member can then tag the bot.
2
Connect your account
The first time you tag the bot, it shows a Connect Migma button. Click it, sign in to Migma, then choose Continue with Slack. This links your Slack identity to your Migma account, so the bot acts as you. You only do this once.

Tag the bot
Mention
@Migma with what you want. Each request runs in a thread on your message.What you can do
Talk to it in plain language:
You can also drop a screenshot in the message and say
@Migma make an email like this for Stripe to clone a design into a branded email.
Every result includes an Open in Migma button to edit, download, or send in the app.
Slack is the chat surface. Migma does the work: brand access, generation, previews, HTML, and inspiration. Sending and exporting stay in Migma.
How brands work
When you name a brand, Migma matches it against your existing brands. If none match, it asks for a website and imports it first. To use a different brand mid-thread, just name it or paste a URL.Connecting and disconnecting
The connection uses Sign in with Slack, so your identity is verified by Slack, never pasted. Migma stores it encrypted and acts as you for later messages. To disconnect, either say@Migma disconnect, or revoke the key named for your Slack workspace under Settings → Developers → API Keys in Migma. After that, the bot asks you to connect again on your next mention.
