Neither is universally 'better'—it depends on your use case. Substack excels for individual newsletter creators seeking direct monetization, while Sendinblue is superior for businesses needing comprehensive marketing automation, SMS, and CRM features. If you're a writer, choose Substack; if you're running a business, Sendinblue offers more tools.
Substack is free with no subscriber limits, making it cheaper for most use cases. Sendinblue offers a generous free tier supporting 100,000 contacts with 300 emails/day, but paid plans start at $25/month. Substack only takes a 10% cut if you offer paid subscriptions, making it cost-effective for monetized newsletters.
Yes, you can export your contacts from Sendinblue and import them into Substack, though the migration process requires manual work. However, note that Substack and Sendinblue serve different purposes—Substack is newsletter-focused while Sendinblue is broader. Switching makes sense only if you're shifting from business email marketing to individual newsletter monetization.
