Mailchimp
What Mailchimp is, who still uses it well, and where a generalist audience tool stops fitting as the list and the data get more specific.

A generalist sender with a long memory
Mailchimp is an email marketing product that grew up on newsletters and small-business campaigns. You keep an audience (their word for the list), send campaigns, and attach automations they now call customer journeys. Intuit owns the company. The product still shows up whenever someone says they need 'the normal email tool' and does not want a CRM project.
Typical use looks like this: a form on a site, tags for what people asked for, a welcome automation, and a campaign when there is news. Agencies also sit on it because clients already have logins. That familiarity is the product as much as the editor.

What people actually do in it
Audiences hold subscribers and the fields you add. Segments are filters on those fields and on campaign behavior. Campaigns are the one-off sends. Automations cover welcome, some ecommerce triggers if you connect a store, and simple drips. The builder is aimed at people who will not write HTML. Reports show opens, clicks, bounces, and unsubscribes with the usual caveats about open tracking.
Mailchimp also bolted on CRM-ish contact views, a website builder, and ads. Those extras matter only if you were going to use Mailchimp as the center of the business. Many customers ignore them and stay in audience plus campaign. That is a valid way to use the tool. Paying for a suite you treat as an ESP is a budget problem, not a moral one.
Where it still fits
A publisher, a local business, a community, or a B2B company with a simple newsletter and no catalog events. If your 'personalization' is first name and one interest tag, Mailchimp is in its original job. Connecting a basic store is possible. Confirm the current ecommerce features on their site rather than assuming Klaviyo-level catalog logic.
Free and low tiers exist and change. They are useful for learning the workflow. Read the send limits and branding rules before you promise a client a paid-looking program on a free account. Domain authentication is worth doing even on a small plan so Gmail knows you are you.
Where teams leave
They leave when the money is in triggered store email that needs inventory, collections, and browse. They leave when the company already standardized on a CRM and does not want a second contact database to keep in sync. They leave when they need a dedicated IP, a complex preference center, or a transactional stream that Mailchimp is not how they want to run.
Leaving hurts if tags were used as a junk drawer. Export audience, unsubscribes, and suppression before you switch. Rebuild segments from fields, not from folklore about what a tag meant in 2019. Mailchimp is not a trap. Messy audiences are.
Common questions
Is Mailchimp still only for email?
Email is still the reason most people log in. The company sells a broader marketing cloud around it. Judge the account by the features you will staff. A logo that says platform does not make your newsletter a platform.
Can I use Mailchimp for password-reset mail?
Transactional mail can live in Mailchimp or in a specialist sender. If you mix resets with promotions on the same domain and reputation, a bad campaign can delay a login email. Many teams put transactional mail on a separate subdomain and tool.
