Klaviyo vs Mailchimp
Ecommerce-first automation at $45/mo against the legacy suite that starts at $13/mo.
What matters for early-stage startups
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
