Mailchimp, simple, popular, pricier at scale
Mailchimp is easy to start and widely known. Its weakness is automation depth and pricing that climbs steeply as your list grows.
Klaviyo, built for e-commerce and automation
Klaviyo's strength is powerful, data-driven automation and segmentation, especially for e-commerce. It's more advanced and costs more for large lists.
Which to choose
Choose Mailchimp for simple newsletters on a small list; choose Klaviyo (or ActiveCampaign) if automation and segmentation are central to your strategy.
Frequently asked questions
Is Mailchimp enough for a small business?
For basic newsletters, yes. If you want automated sequences and segmentation, Klaviyo or ActiveCampaign are stronger.
Can I switch platforms later?
Yes, you can export your list and import it elsewhere. Automations need rebuilding, so pick the platform that fits your growth plans.
