My Personal Recommendations
After using all four platforms for different projects, here's my practical advice:
- Just starting? Start with Mailchimp's free plan. It's the easiest to learn and won't cost you anything while you're getting started.
- Building a creator business? ConvertKit is worth every penny. Its creator-focused features and visual automation builder are unmatched for relationship-building.
- Running an online store? Klaviyo's abandoned cart flows alone typically generate 5-10x the subscription cost in recovered revenue. If you're serious about e-commerce, it's the clear choice.
- High volume, tight budget? Sendinblue's unlimited model is genuinely unique. As your list grows past 5,000+ subscribers, Sendinblue becomes significantly cheaper than competitors.
Final Verdict
Mailchimp wins for beginners and small businesses needing an easy, all-in-one platform. ConvertKit wins for creators prioritizing audience relationships. Klaviyo wins for e-commerce brands serious about revenue. Sendinblue wins for high-volume senders watching their budget.
All four platforms are excellent choices. The right one depends entirely on your business model, goals, and budget. Start with the one that matches your current situation—you can always migrate later as your needs evolve.
