You built your mobile app with Rork because you wanted to go from idea to App Store fast. The AI handles React Native and Expo, and you can even build from your iPhone. With $2.8M from a16z and over 743K monthly visits, Rork has proven the mobile vibe-coding model works. Now you need email that works for mobile apps.

Mobile apps have different email needs than web apps. You need reliable transactional email for authentication flows, but you also need push notifications for real-time engagement. Some platforms handle both, others specialize. Your choice depends on whether you want a unified stack or best-of-breed tools.

This guide covers 12 email marketing tools that work well with Rork mobile applications. I focused on platforms with mobile-friendly APIs and considered the push notification question, since most mobile apps need both. If you are building with a different mobile tool, check out our guides for a0.dev, FlutterFlow, or Draftbit.

1. Sequenzy

Price: Free (100 subscribers) / $49/mo at 10,000 subscribers. Transactional emails included at no extra cost.

Rork apps need reliable transactional email for auth flows. Sequenzy's API handles password resets, receipts, magic links, and verification emails. But unlike pure transactional providers, you also get full marketing automation. Welcome sequences, re-engagement campaigns, and upgrade prompts all flow through the same platform.

The visual sequence builder creates email flows without code. Welcome sequences, trial conversions, and lifecycle emails. The AI generates complete sequences from a description, matching Rork's AI-first approach.

For Rork projects with Stripe integration, Sequenzy's OAuth sync connects automatically. Segment by subscription tier, track revenue attribution, and trigger emails based on payment events. At $49/mo for 10k subscribers, it is 67% cheaper than Klaviyo.

Where it falls short: No push notifications. For mobile apps, you will want to pair Sequenzy with a push service like OneSignal. Email handles account-related messaging, push handles real-time engagement.

Best for: Mobile SaaS founders who want powerful email automation without enterprise complexity. Indie hackers get enterprise-grade features at bootstrap-friendly prices.

2. Customer.io

Price: From $100/mo for up to 5,000 profiles

Customer.io handles email, push, SMS, and in-app messages from one platform. For mobile apps that need unified multi-channel messaging, Customer.io is a serious option.

The mobile SDK tracks user behavior within your Rork app. When users complete actions, Customer.io triggers appropriate messages across any channel. The visual workflow builder handles complex branching logic.

Where it falls short: Expensive at $100/mo minimum. Steep learning curve. Might be overkill for early-stage apps.

Best for: Mobile apps with budget for sophisticated multi-channel automation.

3. Loops

Price: Free (1,000 contacts) / $79/mo at 10,000 subscribers

Loops offers clean, modern email marketing without push notifications. Fast setup, minimal complexity. Good for mobile apps where email handles account messaging and you use a separate push service.

Where it falls short: No push. Basic automation.

Best for: Simplicity-focused founders who will add push separately.

4. MagicBell

Price: From $99/mo

MagicBell focuses on in-app notifications plus email. The platform handles notification infrastructure with a 5-minute setup claim. If you need a notification center inside your Rork app plus email, MagicBell handles both.

Where it falls short: More expensive than email-only options. Focused on notifications, email is secondary.

Best for: Apps needing in-app notification center with email backup.

5. Knock

Price: Free (10,000 messages) / $250/mo for more

Knock offers predictable flat-rate pricing for multi-channel notifications. Unlike per-MAU pricing that scales unpredictably, Knock charges per message volume. Email, push, SMS, and in-app from one API.

Where it falls short: Marketing automation is limited. More notification-focused.

Best for: Apps needing predictable notification pricing.

6. OneSignal

Price: Free (10,000 subscribers) / $9/mo for more

OneSignal is push-first. If your Rork app needs push notifications as the primary engagement channel, OneSignal handles it well. Email is included but not the focus.

Where it falls short: Email features are basic. Push is the strength.

Best for: Pair with Sequenzy for email, OneSignal for push. Best of both worlds.

7. Resend

Price: Free (3,000 emails/month) / $20/mo for 50,000 emails

Resend offers excellent developer experience for transactional email. Clean API, React Email library. Works well with React Native backends.

Where it falls short: No marketing automation. No push.

Best for: Developers wanting clean transactional email who will add marketing separately.

8. Postmark

Price: From $15/mo for 10,000 emails

Postmark focuses on deliverability. For mobile auth flows where emails must arrive reliably, Postmark excels.

Where it falls short: Basic marketing features. No push.

Best for: Critical transactional reliability.

9. SendGrid

Price: Free (100 emails/day) / $20-$90/mo at scale

SendGrid is enterprise infrastructure. Handles volume, offers dedicated IPs. Works with any mobile backend.

Where it falls short: Cluttered interface. No push.

Best for: High-volume transactional needs.

10. Brevo

Price: Free (300 emails/day) / $25/mo at 20,000 emails

Brevo offers email plus SMS at budget prices. For mobile apps where SMS matters, Brevo handles both channels.

Where it falls short: No push. Mixed deliverability.

Best for: Budget-conscious apps needing SMS.

11. Intercom

Price: From $74/mo

Intercom combines email, chat, help desk, and push. If you want one platform for all customer communication, Intercom consolidates it.

The mobile SDK integrates with Rork-built apps. In-app chat, push notifications, and email from one dashboard.

Where it falls short: Expensive. Email is not as deep as dedicated platforms.

Best for: Full customer communication stack.

12. MailerLite

Price: Free (1,000 subscribers) / ~$50/mo at 10,000

MailerLite offers simple email marketing with landing pages. For mobile apps with web marketing presence, MailerLite covers basics.

Where it falls short: Not mobile-focused. No push.

Best for: Simple email needs with landing page requirements.

How to Choose

If you need email + push

Customer.io for integrated multi-channel. Or pair Sequenzy (email) with OneSignal (push) for best-of-breed in each.

If you need transactional reliability

Postmark or Resend for deliverability. Sequenzy if you want marketing included.

If budget is tight

Sequenzy's free tier tests full functionality. OneSignal's free tier handles 10K push subscribers.

Integration Patterns for Rork

REST API from backend

Rork apps typically have a backend (Firebase, Supabase, custom). Call email APIs from your backend, not the mobile client. Keep API keys server-side.

Firebase Cloud Functions

If your Rork app uses Firebase, Cloud Functions call email APIs when database events occur. User signs up, payment succeeds, milestone reached.

Push + Email strategy

Push for real-time: new messages, activity alerts, time-sensitive updates. Email for account-related: receipts, security alerts, weekly digests. Using both channels appropriately improves engagement.

The Bottom Line

For Rork mobile apps, Sequenzy handles email automation excellently. Pair it with OneSignal for push notifications. This gives you best-of-breed in each channel without the complexity of enterprise multi-channel platforms.

If you want everything in one platform and have budget, Customer.io handles email, push, SMS, and in-app together.
