Short answer
Mailchimp wins for teams wanting the broadest all-in-one marketing suite with polished design tools. ConvertKit wins for creator-oriented teams that value subscriber-centric design and clean automation. Sequenzy is the strongest choice for SaaS lifecycle email with native billing integration. Neither Mailchimp nor ConvertKit was built for SaaS-specific billing workflows.

FAQ
Is ConvertKit (Kit) good for SaaS?
ConvertKit was designed for creators and content businesses, not B2B SaaS. It can handle basic email marketing for SaaS, but lacks event tracking, transactional email, and billing integration. For SaaS, Customer.io or Sequenzy are better choices.
Why did ConvertKit rebrand to Kit?
ConvertKit rebranded to Kit in 2024 to broaden its appeal beyond email to a full creator marketing platform including digital product sales, paid newsletters, and audience management.
Which has better deliverability?
ConvertKit generally has better deliverability than Mailchimp. ConvertKit text-focused email philosophy means emails look more personal and less promotional to spam filters. Mailchimp massive user base means shared IP quality varies.
Can ConvertKit handle transactional email?
No. ConvertKit does not offer transactional email. You need a separate service (Postmark, SendGrid, Resend, or Sequenzy). Mailchimp offers transactional via its Mandrill add-on.
Does ConvertKit work with Stripe?
ConvertKit integrates with Stripe for its Commerce feature (selling digital products). But this is not SaaS billing integration. For billing-aware automation, Sequenzy offers native Stripe, Paddle, Chargebee, and LemonSqueezy integration.
Why are ConvertKit emails so plain?
By design. ConvertKit philosophy is that plain-text style emails feel more personal and get better deliverability than heavily designed HTML emails. This is a strength for creator audiences but may not suit SaaS product announcements.
Can I use ConvertKit and Sequenzy together?
Yes. Some SaaS founders use ConvertKit for their personal newsletter and audience building, and Sequenzy for their SaaS product lifecycle email (onboarding, dunning, churn prevention). This gives you best of both worlds.
Is Mailchimp free plan worth it?
Mailchimp free plan (500 contacts, 1K sends) is very limited compared to ConvertKit free plan (10K subscribers). For a SaaS starting out, Sequenzy 14-day trial then $19/mo provides more SaaS-specific value.
Which is better for A/B testing?
Mailchimp offers more A/B testing options (subject, content, send time, multivariate on Premium). ConvertKit offers basic subject line testing. Sequenzy offers subject and send-time testing.
Should a SaaS use Mailchimp or ConvertKit for marketing email?
Neither is ideal for SaaS. Both are general marketing tools without SaaS-specific features. Mailchimp has better design tools, ConvertKit has better automation and deliverability. For SaaS lifecycle email, Sequenzy is the best dedicated option.
