When you cannot settle on a subject line → get it scored as you type
As you type the subject line, Mailchimp rates it on length, word count, punctuation and emoji use, drawing on patterns across the volume it sends.
Why this one: The subject line helper sits outside the "Generative AI Features" bucket that starts at Standard — it is its own row in Mailchimp's plan comparison — so it is the one recipe here that does not need the AI tier. Which plan it reaches is genuinely contested: Mailchimp's feature page says it is "free with every Mailchimp account", while the plan comparison table marks it not included on Free and included from Essentials up. Treat the comparison table as the one to plan around, and expect to find out which is true at the compose screen.
Tweak: Take the emoji advice with a pinch of salt on a business list — the scoring reflects Mailchimp senders in general, not the people on your list.
When someone new joins your list → welcome them without you being there
Open Automations, pick the flow template for welcoming new contacts, choose your audience, edit the email, switch it on. The signup itself is the trigger (the "when" — the event that starts an automation); Mailchimp calls it the starting point.
Why this one: Essentials caps a marketing automation flow at four steps, which happens to be exactly the shape of a welcome sequence — so this is the one automation you can grow into on the cheapest paid tier without paying for Standard's 200-step ceiling.
Tweak: Rather than building a second flow later, add a delay and a follow-up email inside this one while you still have steps spare.
When you have written a rough paragraph → ask the editor to shorten it or shift its tone
Inside a Paragraph, Heading or Button block in the email builder, Write with AI takes your prompt or one of its preset suggestions and returns a rewrite you accept or discard.
Why this one: Mailchimp also puts the same tool in the message box of the SMS builder, so one recipe covers cutting a paragraph you already like down to text-message length — the rewrite is anchored to copy you wrote rather than starting from a blank prompt.
Tweak: If it is missing on a plan that should have it, that is the staged beta rollout rather than a setting you got wrong.
When a shopper abandons a cart → let the AI draft the whole recovery sequence
With a supported store connected, Mailchimp's AI-powered flow templates generate branded emails for nine standard sequences — abandoned cart, price drop on a cart item, birthday, sign-up anniversary, win-back and more — pulling design from your Brand Kit. You pick the audience, review what it wrote, then activate.
Why this one: Three conditions have to be true at once — a Standard plan or higher, a US primary mailing address, and one of Mailchimp's supported store connectors — and Mailchimp's help page names all three, so you can rule this in or out before you commit to a contact tier.
Tweak: No store, or not in the US? The same sequences exist as ordinary flow templates in the same browser, with the timing pre-set and the writing left to you.
When you want to know why last month worked → ask, instead of building a report
Analytics AI answers questions about campaign performance, audience behaviour and revenue in conversation, reading your connected store data alongside your send history.
Why this one: Mailchimp launched it to remove the export-and-pivot step, so the answer comes back in revenue terms rather than as an open rate you then have to interpret.
Tweak: Mailchimp also publishes connectors for ChatGPT and Claude on the same tiers, so you can ask the same kind of question from whichever assistant you already have open.
