Loops vs Mailchimp
SaaS lifecycle and transactional email versus a broad legacy marketing suite.
What matters for growth and lifecycle teams
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.

For lifecycle and activation work running behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, the two are level on every priority that can be scored here, so the choice comes down to price and to which product your team would rather operate. On free tier, Loops offers 1,000 contacts and 4,000 sends/mo on the Free plan against 500 contacts, 1,000 sends/month from Mailchimp / Mandrill. That ordering reflects this audience. Weigh the same table differently and the answer changes.

Mailchimp / Mandrill
