SendiventvsResend

How Sendivent and Resend think about notifications

Resend is a modern email API built for developers. It's focused on making email delivery simple and reliable, with excellent developer experience and React integration for building email templates.

Sendivent is a multi-channel notification platform. Your backend emits events (like user_signed_up or invoice_overdue), and Sendivent routes them to the right channels — email, SMS, Slack, and soon WhatsApp and push — based on your configuration.

The core difference: Resend is the best-in-class tool for email. Sendivent is the notification layer that handles all your product communications in one place.

When email-only isn't enough

If your product only sends email, Resend is excellent. But most modern products need more:

• Urgent alerts → SMS or push (like payment alerts)
• Team notifications → Slack
• Transactional updates → Email (like order confirmations)
• Real-time alerts → Webhooks

With Resend, you'd wire up separate providers for each channel. With Sendivent, it's one API call and we handle the routing.

Developer experience

Both platforms prioritize developer experience, but differently:

Resend's approach:

• React-based email templates
• Clean, minimal API
• Excellent TypeScript support
• Focus on email deliverability

Sendivent's approach:

• Event-based API (sendivent.track('event', data))
• Templates managed in dashboard, not code
• Multi-channel from a single call
• Built-in localization

Pricing comparison

Resend charges per email sent, with a free tier and paid plans based on monthly email volume. Exact numbers change over time, so check their pricing page for current details.

Sendivent charges per person notified. Our free tier includes 1,000 people/month. A single person receiving email + SMS + Slack counts as one person, not three messages.

This matters when you notify the same user across multiple channels — with per-message pricing, costs multiply.

Migration path

If you're currently using Resend and want to add more channels, you have two options:

1. Keep Resend for email, add separate providers for SMS, Slack, etc.
2. Switch to Sendivent for a unified notification layer

Option 1 means managing multiple integrations. Option 2 means one dashboard, one API, one billing relationship.

Bottom line

Choose Resend if email is your only channel and you want the best email-specific developer experience, especially if you love building email templates in React.

Choose Sendivent if you need (or will need) multiple channels, want simpler pricing, or want your product and support teams to manage notification content without deploying code. Learn more about our email deliverability and notification templates features.

Code Comparison

With Resend (email only, React templates)

import { Resend } from 'resend';
import { WelcomeEmail } from './emails/welcome';

const resend = new Resend('re_123456789');

// Beautiful React-based email templates
await resend.emails.send({
  from: 'onboarding@example.com',
  to: user.email,
  subject: 'Welcome!',
  react: WelcomeEmail({ name: user.name })
});

// Need SMS? Add another provider
// Need Slack? Another integration
// Templates live in code — deploys required for copy changes

With Sendivent (multi-channel, dashboard templates)

await sendivent
  .event('user.welcome')
  .to({ email: user.email, phone: user.phone })
  .payload({ name: user.name })
  .send();

// Templates in dashboard (not code)
// Product team can edit copy without deploys
// Multi-channel from one call

The trade-off: Resend's React templates are powerful for developers. Sendivent's dashboard templates are accessible to everyone.
