The Mailchimp destination sends emails using Mandrill (Mailchimp Transactional API). All recipient and content information comes from your incoming data—no Mailchimp list or audience is used. You can send one email per row or one email per group when using Group By.
You need a Mandrill API key from Mailchimp: Account & Billing → Extras → Mandrill. This is separate from the Marketing API key. Verify your sending domain in Mandrill so emails can be delivered.

Credentials

Create a Mailchimp destination and complete the Credentials step:
  • Mandrill API key (required): Your Mandrill API key from Mailchimp.
  • From email: Sender address for outgoing emails. Must be a verified domain in Mandrill. Defaults to noreply@less.tech if empty.
  • From name: Display name for the sender.

Using the Destination tool

On the canvas, add a Destination tool and select your Mailchimp destination. Configure:
  • Group by (optional): When set, one email is sent per unique combination of the selected columns. Leave empty for one email per row.
  • Recipient email column: The column in your data that contains the recipient email address. When grouped, all unique emails in each group receive the email.
  • Subject: Email subject line. Use [ColumnName] to insert values (only group-by columns when grouping is active). Type [ to see autocomplete suggestions.
  • Email body: Rich text editor with formatting. Type [ to autocomplete column names. Use [DATA_TABLE] where you want the inline data table to appear.
  • Attach dataset as: None, CSV, or Excel. When Group by is set, each email gets its group’s data as the attachment.
For one email per row, leave Group by empty — all columns can be used as placeholders. For one email per group (e.g. per region or per customer), select the columns to group by — only those columns are available as placeholders.
