Updated October 20, 2026 · By [Robert Breen](https://learn.ynteractive.com/content/about) ## Why it matters for a small business Most small firms already have the list: past clients, event guests, newsletter sign-ups sitting in a spreadsheet. Mailchimp turns that list into something you can send to properly, with an unsubscribe link, open and click reports and the option to send only to a segment instead of everyone. Its help center shows the basic path: **Audience**, then **Add contacts**, then **Import contacts**, and upload a CSV or TXT file that has an **Email Address** column. You match each column to an audience field, set the marketing status and click **Complete Import**. Mailchimp asks you to confirm you have permission to email anyone you import as subscribed. When you create an email, the checklist walks you through **To**, **From**, **Subject**, **Send time** and **Content**. In **To** you can pick all subscribers or a segment, or exclude tags. On Standard and higher plans, **Write with AI** can draft subject lines and copy, and Mailchimp says to review AI output before sending. ## In a real lesson: Protect Your Sender Reputation Before a Big Send using no2bounce The [no2bounce lesson](https://learn.ynteractive.com/content/no2bounce-clean-email-list-sender-reputation) does not use Mailchimp. It covers the step right before a big send. Nora runs marketing at Lantern Hill Venue, a made-up event space. Her last open house invite went to 600 contacts and 54 bounced, which is 9 percent. Bounces hurt sender reputation, so more good mail lands in spam. In no2bounce she uploads the contact CSV, picks the **email** column, clicks **Validate** and then downloads only the **Deliverable** addresses. The lesson ends with one instruction: load that file into your email tool. That email tool is where Mailchimp fits. You import the clean file under **Import contacts**, tag it (for example "open house"), and send the next invite to that tag only. The validator protects the list; Mailchimp does the sending, the unsubscribes and the reporting.

Mailchimp sends marketing email to a list with unsubscribe links, sign-up forms and campaign reports, which is what bulk sends need. See [email deliverability](https://learn.ynteractive.com/content/glossary/email-deliverability). ### Audience vs segment The audience is your whole contact list in Mailchimp. A [segment](https://learn.ynteractive.com/content/glossary/audience-segmentation) is a filtered slice of it, such as everyone with one tag, that you choose in the **To** step. ## Tips - Clean the list before the first import so old bounced addresses never count against you. - Import one marketing status per file; Mailchimp only accepts one status per import. - Tag each import with where the contacts came from, then send to the tag. - Read every AI-written subject line and paragraph before you send. ## Related terms [Email bounce](https://learn.ynteractive.com/content/glossary/email-bounce) · [Email deliverability](https://learn.ynteractive.com/content/glossary/email-deliverability) · [Audience segmentation](https://learn.ynteractive.com/content/glossary/audience-segmentation) · [Drip campaign](https://learn.ynteractive.com/content/glossary/drip-campaign) · [Email opt-in](https://learn.ynteractive.com/content/glossary/email-opt-in) · [CSV](https://learn.ynteractive.com/content/glossary/csv) ## More Web apps terms [Metricool](https://learn.ynteractive.com/content/glossary/metricool) · [Miro](https://learn.ynteractive.com/content/glossary/miro) · [Mixo](https://learn.ynteractive.com/content/glossary/mixo) · [Notion](https://learn.ynteractive.com/content/glossary/notion) ## Where you use it: free lessons - [Protect Your Sender Reputation Before a Big Send using no2bounce](https://learn.ynteractive.com/content/no2bounce-clean-email-list-sender-reputation) (no2bounce, 8 min) - [n8n: Weekly Client Status Emails from a Google Sheet, Written by AI](https://learn.ynteractive.com/content/weekly-client-status-email-google-sheets-ai-n8n) (n8n, 14 min) ## AI tools that use it - [Mailchimp](https://learn.ynteractive.com/content/ai-tools/marketing-social#tool-mailchimp) - [no2bounce](https://learn.ynteractive.com/content/ai-tools/email-inbox#tool-no2bounce) ([free lesson](https://learn.ynteractive.com/content/no2bounce-clean-email-list-sender-reputation)) [More terms by tool](https://learn.ynteractive.com/content/glossary/ai-tool-terms) ## Frequently asked questions **Is Mailchimp free?** Yes, Mailchimp has a free plan for early-stage senders with a contact limit and monthly and daily send limits.
