Understanding the Difference
This comparison requires context: Resend and Sequenzy serve different primary use cases.
- Resend is a transactional email API for developers. It's optimized for password resets, notifications, receipts. Beautiful API, React Email integration, regional sending, detailed analytics.
- Sequenzy is a full email platform for SaaS founders. Transactional + marketing, visual automations, subscriber management, Stripe integration. Also supports React Email.
The key difference: Resend doesn't have email sequences. If you need automated drip campaigns, welcome series, or any multi-step email flows, you'd need to build that yourself with Resend.
When should you choose Sequenzy?
1. You Need Email Sequences
This is the biggest difference. Sequenzy has a visual automation builder for welcome sequences, trial expiry flows, onboarding drips, and churn prevention. Resend has no sequence functionality at all. With Resend, you'd need to build all sequence logic in your own code.
2. You Need Marketing Emails Too
If you want to send newsletters, campaigns, or promotional emails—not just transactional—Sequenzy is built for it. Resend has "Audiences" for marketing (at extra cost), but it's basic and doesn't include sequences.
3. You're Not a Developer
Sequenzy has a visual email editor and campaign builder that non-developers can use. Resend is API-first—you need developer involvement for most workflows.
4. You Need Stripe Integration
Sequenzy syncs with Stripe for SaaS subscription management—MRR, churn, subscription triggers. Resend doesn't have billing integrations.
When should you stick with Resend?
1. You Only Need Transactional Emails (No Sequences)
If your use case is purely transactional—password resets, order confirmations, notifications—and you don't need automated sequences, Resend is purpose-built for this. It's fast, reliable, and focused.
2. You Need Granular Transactional Analytics
Resend has very detailed transactional email analytics—delivery status, bounce reasons, engagement metrics with granular data. We have good campaign analytics, but Resend's transactional-specific metrics are more detailed.
3. You're a Developer Who Loves Great DX
Resend's API is genuinely beautiful. Clean endpoints, modern design, excellent documentation. If developer experience matters to you (and it should), Resend is best-in-class.
4. You Need Regional Sending
Resend can send emails from the region closest to your users (North America, South America, Europe, Asia). This reduces latency. We don't have regional sending.
5. You Need a Dedicated IP Now
Resend offers dedicated IPs for $30/mo on their Scale plan. We're adding dedicated IPs soon, but Resend has them now.
Honest Limitations of Sequenzy
- Less elegant API: Resend's API is genuinely prettier. Our API works well but isn't as polished.
- No regional sending: We don't have multi-region infrastructure.
- Dedicated IPs coming soon: Not available yet, but on our roadmap.
- Fewer SDKs: Resend has more language coverage.
Honest Limitations of Resend
- No email sequences: This is the big one. No drip campaigns, welcome series, or automated flows. You'd build that yourself.
- Marketing costs extra: Audiences is a separate paid add-on, and it's basic.
- Developer-required: Non-technical team members can't really use it independently.
- No Stripe integration: No native billing/subscription management.
- Data retention limits: Free tier has 1-day retention. Even Pro only has 3 days.
