When should you choose Sequenzy?

Sequenzy is the better choice for SaaS companies that need more than email infrastructure:

  • SaaS founders who need marketing automation + transactional unified
  • Small-to-medium teams who want ready-to-use features without enterprise setup
  • Stripe users who want automated emails based on billing events
  • Non-developers who need visual email builders, not HTML templates
  • Companies under 500k emails/month who don't need enterprise scale

When should you stick with SparkPost?

SparkPost is the better choice for enterprise email infrastructure:

  • High-volume senders sending millions of emails monthly
  • Enterprises needing advanced deliverability tools and predictive analytics
  • Multi-tenant platforms that need subaccounts for clients
  • Companies requiring IP warmup automation for new sending domains
  • Teams with dedicated email operations who can manage infrastructure

Honest Limitations of Sequenzy

  • Not built for enterprise-scale sending (millions per month)
  • No predictive analytics or AI-powered deliverability insights
  • No Email Health Score for real-time reputation monitoring
  • No automated IP warmup tools
  • Basic multi-tenant compared to SparkPost's subaccounts
  • Newer platform with less scale testing

Honest Limitations of SparkPost

  • No marketing automation—purely transactional infrastructure
  • No visual email builder (HTML templates only)
  • No campaign management or broadcast features
  • No subscriber segmentation for marketing
  • Enterprise pricing can be expensive for small teams
  • Owned by MessageBird—ongoing platform changes
