Post a message in Discord when someone joins the mailing list in Mailchimp

What each client fills in

Mailchimp: Audience ID

Audience → Settings → Audience name and defaults: the Audience ID.

The accounts it needs

Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.

• 

  In the client’s Mailchimp: Profile → Extras → API keys → Create A Key. The server prefix is the part after the dash (us21).

• 

  In the client’s Discord server: Server Settings → Integrations → Webhooks → New Webhook → pick the channel → Copy Webhook URL.

After you install it

It lands switched off. The client’s checklist holds exactly this:

1. Connect the client’s Mailchimp, for “Someone joins the mailing list”
2. Connect the client’s Discord, for “Post a message”
3. Fill in Mailchimp: Audience ID (Audience → Settings → Audience name and defaults: the Audience ID)
