Frequently Asked Questions

Is ConvertKit or MailerLite better for SaaS?

Neither is designed for SaaS. Both are general email marketing platforms. For SaaS lifecycle email (trial conversion, dunning, churn prevention), use a purpose-built tool like Sequenzy. ConvertKit and MailerLite can handle basic newsletters and announcements for SaaS products.

Which is cheaper: ConvertKit or MailerLite?

MailerLite is cheaper at every subscriber tier. MailerLite starts at $10/mo for 1K subscribers, while ConvertKit Creator starts at $25/mo. However, ConvertKit has a more generous free plan (10K subscribers vs. 1K).

Which has better deliverability?

ConvertKit has a slight edge due to its text-focused email philosophy, which email providers tend to trust more. Both have strict sender approval processes. Sequenzy benefits from SaaS-only IP pools.

Can I use ConvertKit for transactional email?

No. Neither ConvertKit nor MailerLite supports transactional email. You would need a separate service (MailerSend, Postmark, Resend). Sequenzy includes transactional email with SaaS templates.

Which has a better email editor?

MailerLite has a significantly better visual editor with more templates and design flexibility. ConvertKit intentionally uses simpler, text-focused designs that tend to have better deliverability.

Can I sell digital products with both?

Yes. ConvertKit has more robust commerce features (tip jars, subscriptions, recommendations). MailerLite supports digital product sales with Stripe integration. Both support selling e-books, courses, and downloads.

Is ConvertKit now called Kit?

ConvertKit rebranded to "Kit" in 2024. The product is the same. Both names are used.

Which is better for a SaaS product newsletter?

Both are good for newsletters. MailerLite offers more visual design flexibility. ConvertKit offers the recommendations network for audience growth. For plan-aware product announcements (different content for free vs. paid users), Sequenzy is the better choice.

Can I migrate between them easily?

Yes. Both migrations are relatively easy (3-7 days). Subscriber data exports via CSV. The main challenge is recreating automations and landing pages in the new platform.

Do both support GDPR?
