SaaSpark Mailchimp's roots are in newsletter sending for small businesses. If you're running a SaaS, you'll outgrow it the moment you need product-event triggered automations.
**Loops** is the modern marketing-email default for SaaS. If your sending is actually transactional (welcome emails, password resets), look at **Resend** instead — different category, but often what people ask for when they say they're "looking for Mailchimp alternatives".
Loops
Marketing email built for modern SaaS — automations, broadcasts.
- Category: marketing-email
Why we picked it: Built specifically for SaaS — automations, segments, broadcasts.
Resend
Email API for developers. Send transactional and marketing email at scale.
- Category: transactional-email
Why we picked it: If your need is transactional email rather than marketing campaigns.
