| Option | What starts it | Good at | Keep in mind |
|---|---|---|---|
| Letaido AI agent | A new Mailchimp subscriber, a mention of @Letaido in Slack, a daily or weekly schedule, or you asking | Subscriber posts with company and job title, campaign reports with top links and bounce, unsubscribe and spam flags, a weekly recap, and draft checks with a test email | Mailchimp is only read, except the test email the draft check sends to the person who asked. These featured jobs never send or schedule campaigns. Invite the Letaido bot to each channel |
| Mailchimp app for Slack | Subscribes, unsubscribes and campaign sending status in the audience you pick | Simple alerts in the Slack channel you choose | Made by Slack. Alerts only: no open or click results, no reports, and nothing starts from Slack |
| Zapier, n8n and similar | A Mailchimp trigger such as New or Updated Subscriber, New Campaign or Link Clicked, a schedule, or a Slack message | Fixed recipes, such as a Slack message for each new subscriber, unsubscribe or new campaign | You build and look after each recipe. On Zapier, campaign and link click triggers check for new data on a timer, not the moment it happens. Reports need extra steps you set up, and a draft check or test email needs custom API steps |

Frequently asked
Does Mailchimp integrate with Slack? +
The Mailchimp app for Slack, made by Slack, posts alerts when people subscribe or unsubscribe and when a campaign is sent. With Letaido, its AI agent Leta uses Mailchimp and Slack in the same job: it posts new subscribers with their company and job title, reports on each campaign, and checks drafts from Slack.
How do I connect Mailchimp and Slack to Letaido? +
Paste a Mailchimp API key, then create the Slack app from Letaido's manifest and invite the Letaido bot to the channels it posts in. For the subscriber job, Letaido registers the audience webhook in Mailchimp for you, so there is no URL to paste.
Can it post new Mailchimp subscribers to Slack? +
Yes. When someone signs up to your audience through a form, Leta posts their name, email, company, job title, signup source and country to the channel you pick, with Work email: Yes or No. Imports and contacts your team or an API adds are skipped.
Is there a way to get Mailchimp campaign reports in Slack? +
Yes. One job posts a report for each campaign sent 24 to 48 hours earlier: open and click rate next to the audience average, the top three links, and bounces, unsubscribes and spam complaints flagged against that audience's 90 day average. Another posts a recap of the week's campaigns every Friday.
Does it send or schedule Mailchimp campaigns from Slack? +
This draft check never sends or schedules the campaign. Mention @Letaido with a draft's name and it runs Mailchimp's send checklist, sends a test email to the person who asked and replies in the thread with what still needs fixing. These featured jobs never send or schedule campaigns; you send the campaign from Mailchimp.
Can Zapier connect Mailchimp and Slack? +
Yes. A Zapier recipe follows the steps and message template you set up, such as one for each new subscriber or new campaign. Leta can also compare results with your audience averages and check a draft when someone asks in Slack.
Will it ask before it posts to Slack? +
Yes. Allow all read operations once per app; approve each kind of write once.
