When should you choose Sequenzy?

1. You Need Email Marketing

OneSignal shines for mobile apps with push notifications. If you're building a SaaS product where email is your primary communication channel, Sequenzy is purpose-built for that. Native Stripe integration, SaaS-specific automations, and AI-generated sequences.

2. Email Marketing Is Your Focus

OneSignal added email to become multi-channel, but push is still their core. Their email features are functional but not as sophisticated as email-first platforms. If email is your primary channel, Sequenzy's email campaigns and AI sequences are more powerful.

3. You Want Native Stripe Integration

Sequenzy syncs directly with Stripe - customer data, MRR, subscription changes, and churn signals flow automatically. OneSignal requires custom integration work for billing data. If your business runs on Stripe, we make it effortless.

4. You Want Predictable Pricing

Sequenzy is $49/mo for 120k emails. OneSignal's usage-based pricing can vary month to month based on push volume, email sends, and SMS. If you prefer knowing exactly what you'll pay, our pricing is simpler.

When should you stick with OneSignal?

1. Push Notifications Are Critical

OneSignal is a push notification leader. Web push, mobile push, excellent SDKs for every platform. We don't do push notifications. If push is important to your product, OneSignal is the right choice.

2. You Have a Mobile-First Product

OneSignal has native SDKs for iOS, Android, React Native, Flutter, Unity, and more. Sequenzy has no mobile SDK. If you're building mobile apps and need in-app messaging plus push, OneSignal is built for that.

3. You Need Multi-Channel Messaging

OneSignal does push, email, SMS, and in-app messaging from one platform. We only do email. For true multi-channel communication, OneSignal orchestrates across channels.

4. You Want Visual Journey Builders

OneSignal has visual journey workflows with branching logic and multi-step automations. Our approach is simpler sequences. If you need complex visual journey building, OneSignal is more powerful there.

5. You Want a Bigger Free Tier

OneSignal's free tier includes 10,000 emails/month and unlimited push. Our free tier is 2,500 emails/mo, unlimited contacts. If you're testing or have limited budget, OneSignal's free tier is more generous.

Pricing at Every Scale

Contacts Sequenzy OneSignal (Email Only) Difference
500 Free (2,500 emails/mo) Free (10k emails) OneSignal more generous free tier
1,000 Free (2,500 emails/mo) Free (10k emails) OneSignal more generous free tier
5,000 $29/mo (60k emails) ~$15-25/mo (usage-based) Similar cost
10,000 $49/mo (120k emails) ~$30-50/mo (varies) Similar cost
25,000 $99/mo (300k emails) ~$75-150/mo (varies) Sequenzy more predictable
50,000 $199/mo (600k emails) ~$150-300/mo (varies) Sequenzy more predictable
100,000 $349/mo (1.2M emails) Custom pricing Sequenzy more predictable

OneSignal's email pricing is usage-based ($1.50/1k after 20k free on Growth plan), so costs vary significantly by send volume. Push notifications have separate pricing ($0.012/MAU). Sequenzy's flat email-volume pricing is more predictable.

Who Should Use Each Platform

Choose Sequenzy if you are:

  • A SaaS founder who needs email marketing with Stripe/Paddle/Lemon Squeezy integration
  • 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
  • Preferring predictable, flat monthly pricing over usage-based billing
  • A developer who wants a clean REST API for transactional and marketing emails

Choose OneSignal if you are:

  • Building a mobile app that needs push notifications as the primary channel
  • Needing multi-channel messaging (push + email + SMS + in-app) from one platform
  • A mobile developer wanting native SDKs for iOS, Android, React Native, or Flutter
  • Running a content or media app where push notifications drive engagement
  • Wanting visual journey builders with cross-channel branching logic
  • Looking for a generous free tier for push notifications (unlimited)

Real Setup Time

Task Sequenzy OneSignal
Account creation 2 minutes 5 minutes
Domain verification 10-15 minutes 10-15 minutes
First email campaign 5 minutes (AI-generated) 15-20 minutes (manual)
Stripe integration 5 minutes (native) 30+ minutes (custom)
Push notification setup N/A (email only) 15-30 minutes (SDK integration)
First automation 10 minutes 20-30 minutes
Mobile SDK integration N/A 30-60 minutes per platform
Import contacts 5 minutes 10 minutes

Sequenzy is faster for email marketing. OneSignal requires more setup for push notifications and mobile SDK integration, but that setup unlocks capabilities Sequenzy doesn't have.

How to Migrate from OneSignal to Sequenzy

Note: If you use OneSignal for push notifications, you'll likely keep OneSignal for push and use Sequenzy for email. This migration guide covers the email portion.

Step 1: Export Your Email Subscribers

Export your email subscriber list from OneSignal. Go to Audience → Export and download your contacts as CSV. Include email addresses, tags, and any custom attributes.

Step 2: Create Your Sequenzy Account

Sign up at Sequenzy and connect your Stripe account if you run a SaaS business. This automatically syncs subscription data, MRR, and churn signals.

Step 3: Set Up Domain Authentication

Add DNS records for SPF, DKIM, and DMARC. Sequenzy provides the exact records during onboarding. This ensures good deliverability from day one.

Step 4: Import Your Contacts

Upload your CSV export to Sequenzy. Map email addresses, names, and any custom attributes. Sequenzy supports unlimited contacts on all plans.

Step 5: Recreate Email Automations

Rebuild your email workflows in Sequenzy. Use AI sequence generation to create email content faster. Set up trial, onboarding, and lifecycle automations with SaaS-specific triggers.

Step 6: Keep OneSignal for Push

If you use push notifications, keep OneSignal running for that channel. Use Sequenzy for email marketing and OneSignal for push — they serve different purposes well.
