Mailchimp

luftflow keeps your Mailchimp audience up to date. It can:

• Add or update a subscriber: someone new joins the audience as subscribed; someone already in it has their first name updated.
• Tag a subscriber, such as customer once they pay, so a campaign reaches only the people it fits.

Only add people who agreed to hear from you.

Keys

In Mailchimp, open Profile → Extras → API keys and create a key. Paste it into Connectors → Mailchimp, and give the server prefix: the part after the dash at the end of the key, such as us21. A separate test audience for staging keeps test runs out of your real list.

Audiences

A step names an audience by its id, under Audience → Settings → Audience name and defaults.
