Sequenzy vs Mailchimp: Which is Better for Startups in 2026?

Overview

Mailchimp is the most recognized email marketing tool in the world. Sequenzy is a newer player built specifically for startups with native billing integrations. This comparison will help you understand which one fits your startup better.

The short answer: if you are a SaaS startup using Stripe, Polar, Creem, or Dodo, Sequenzy is the better choice. If you need the widest possible integration ecosystem and brand recognition, Mailchimp works.

Key Differences

Billing Integration

Sequenzy has native OAuth integrations with Stripe, Polar, Creem, and Dodo. Your billing data syncs automatically. You can segment subscribers by MRR, LTV, plan type, and payment status without writing code. Revenue attribution shows exactly which emails drive actual revenue.

Mailchimp has a basic Stripe integration, but it does not sync SaaS-specific metrics. You cannot segment by MRR or see revenue attribution. For SaaS startups, this is a significant limitation.

Pricing at Scale

Mailchimp starts cheaper at $13/mo but gets expensive quickly. The free tier dropped from 2,000 to just 500 contacts. At 10,000 contacts, you are looking at $100+/mo. Advanced automation requires higher tiers.

Sequenzy at $19/mo includes 20,000 emails with advanced automation and billing integration included. For most startups, Sequenzy offers better value as you scale.

Email Types

Sequenzy handles both transactional (password resets, receipts) and marketing emails in one system. One sender reputation, one dashboard, one API.

Mailchimp separates transactional email into Mandrill, a separate product with separate pricing. This adds complexity and cost if you need both.

Pros and Cons

Who Should Choose What

Choose Sequenzy if:

• You are a SaaS startup using Stripe, Polar, Creem, or Dodo
• You want to track which emails drive actual revenue
• You need both transactional and marketing email
• You want startup-specific segmentation (MRR, LTV, plan)
• You prefer better value at scale

Choose Mailchimp if:

• You need the widest possible integration ecosystem
• Brand recognition matters for your use case
• You are not a SaaS startup
• You want built-in landing pages
• You are at very low volume and want the free tier

The Bottom Line

For SaaS startups, Sequenzy is the clear winner. The native billing integrations and revenue attribution provide insights Mailchimp simply cannot offer. You will understand which emails actually drive MRR, not just opens and clicks.

Mailchimp remains a solid choice for non-SaaS businesses that need broad integration support and do not need billing-specific features. But for startups serious about growth, Sequenzy delivers more value.
