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

Pricing at Every Scale

Emails/Month Sequenzy SparkPost Difference
2,500 Free $20/mo (Starter, 50k) Sequenzy free for low volume
15,000 $19/mo $20/mo (Starter, 50k) Similar cost
50,000 $29/mo (60k) $20/mo (Starter) SparkPost cheaper (API only)
100,000 $49/mo (120k) ~$90/mo (Premier 100k) Sequenzy cheaper + marketing
300,000 $99/mo ~$225/mo (Premier) Sequenzy $126/mo cheaper
600,000 $199/mo ~$525/mo (Premier) Sequenzy $326/mo cheaper
1,200,000 $349/mo Custom pricing Sequenzy significantly cheaper

SparkPost's Starter is cheap for pure transactional. But Sequenzy includes marketing automation, AI content generation, and Stripe integration — features you'd need separate tools for with SparkPost.

Who Should Use Each Platform

Choose Sequenzy if you are:

  • A SaaS founder who needs marketing automation + transactional in one platform
  • Running a subscription business and want automated trial, churn, and upgrade emails
  • Looking for AI-generated email sequences to save time on content creation
  • Wanting Send Time Optimization to maximize email engagement
  • A non-developer who needs visual email tools, not HTML templates
  • Preferring one platform for all email needs

Choose SparkPost if you are:

  • An enterprise sending millions of emails monthly
  • Needing predictive analytics and AI-powered deliverability insights (Signals)
  • Wanting automated IP warmup for new sending domains
  • Running a multi-tenant platform needing subaccount architecture
  • Already in the MessageBird/Bird ecosystem
  • Prioritizing enterprise-grade delivery infrastructure over features

How to Migrate from SparkPost to Sequenzy

Step 1: Create Your Sequenzy Account

Sign up at Sequenzy and connect your Stripe account for automatic subscription data sync.

Step 2: Set Up Domain Authentication

Add DNS records for SPF, DKIM, and DMARC. Sequenzy provides the exact records during onboarding.

Step 3: Update Your API Integration

Replace SparkPost API calls with Sequenzy's REST API. Update endpoints, authentication, and payload format.

Step 4: Build Marketing Capabilities

Use Sequenzy's visual automation builder and AI sequence generation to create marketing workflows that SparkPost doesn't offer.

Step 5: Monitor Deliverability

If you relied on SparkPost Signals and dedicated IPs, monitor shared IP deliverability carefully. Run both platforms in parallel for 1-2 weeks.

Step 6: Complete the Switch

Once satisfied with deliverability, fully switch to Sequenzy and cancel SparkPost.
