Resend is one of the best things to happen to developer email in years. Clean API, excellent documentation, React Email integration, and a free tier that covers most side projects. If you're a developer who needs to send transactional email, Resend is a genuinely great choice.
PushMail is built on the same developer-first philosophy. But it covers different ground.
This post lays out the honest difference between the two, what each does well, and when you should choose one over the other.
What Resend Is
Resend is a modern transactional email API. You call their API, your email gets delivered. The experience is clean, the SDKs are solid, and the React Email integration is native and well-executed. They've built exactly what they set out to build.
Their free tier covers 3,000 emails per month. For a lot of developers, that's all they'll ever need.
What PushMail Is
PushMail is a complete email infrastructure platform. It sends transactional email, yes — but it also manages contacts, runs drip sequences, schedules campaigns, validates addresses, normalizes webhooks across providers, and supports ten different email providers including Resend itself.
The mental model: Resend is a delivery layer. PushMail is a delivery layer plus contact management plus automation plus multi-provider routing.
Feature Comparison
| Feature | Resend | PushMail |
|---|---|---|
| Transactional email | Yes | Yes |
| React Email templates | Yes (native) | No (HTML/{{variables}}) |
| Marketing campaigns | Audiences (beta) | Yes |
| Drip sequences | No | Yes (with conversion goals) |
| Contact management | Audiences (basic) | Yes (contacts, lists, tags) |
| Email validation | No | Yes (free, at send time) |
| BYOK providers | No | Yes (10 providers) |
| Multi-site | No | Yes |
| Scheduled sending | Yes | Yes |
| Webhooks | Yes | Yes (normalized from 10 providers) |
| Batch sending | Yes | Yes |
| Multi-provider | No | Yes (SendGrid, SES, Postmark, Mailgun, SparkPost, Brevo, Mailjet, Mandrill, Resend, Elastic Email) |
| Trust/reputation system | Unknown | Yes (transparent thresholds) |
| Free tier | 3,000 emails/mo | $5 credits (~1,666 emails) |
Pricing Comparison
Let's be direct: Resend is cheaper, especially at lower volumes. Their free tier is generous and their paid plans are aggressive.
| Volume | Resend | PushMail |
|---|---|---|
| 5,000/mo | Free | $15 |
| 50,000/mo | $20/mo | $110 |
| 100,000/mo | $45/mo | $210 |
| 500,000/mo | Custom | $710 |
PushMail's pricing reflects the broader platform. You're not just paying for delivery — you're paying for contact management, sequences, campaigns, validation, and multi-provider routing. If you only need delivery, Resend's pricing will be hard to beat.
The React Email Angle
Resend's tight integration with React Email is genuinely good. You write components, they handle rendering, the workflow feels native.
PushMail uses plain HTML with {{variable}} substitution. It's less elegant for template authoring, but it's framework-agnostic and easy to reason about.
If you love React Email, you can still use it with PushMail. Render your components to HTML on your end and POST the result to PushMail's API. You lose the native integration, but you keep your template workflow.
Where PushMail Wins
You need drip sequences
Resend has no drip sequence feature. If you want to enroll a user in a welcome sequence — email on day 1, follow-up on day 3, check-in on day 7 — you need to build that yourself or add a separate tool to your stack.
PushMail includes sequences with conversion goals. Define the steps, set delays, specify a goal event, and PushMail handles enrollment, timing, and completion tracking.
You need marketing campaigns
Resend's Audiences and Broadcasts are in beta. PushMail campaigns are production-ready: schedule a send, target a list, track opens and clicks, view stats.
If you're running a newsletter or any kind of broadcast email alongside your transactional sends, PushMail handles both from one platform.
You need multi-provider flexibility
Resend locks you into their infrastructure. That's fine until you need to switch — whether for pricing, deliverability, or regional requirements.
PushMail supports ten providers: SendGrid, SES, Postmark, Mailgun, SparkPost, Brevo, Mailjet, Mandrill, Resend, and Elastic Email. Bring your own API keys, point PushMail at whichever provider you want, and switch without changing your application code.
You need email validation
PushMail validates every email before sending: syntax, MX record checks, disposable domain detection, and bounce suppression from your historical sends. It's free and runs automatically.
Resend does not include email validation. Bad addresses fail at delivery time.
You need multi-site
If you're building a platform where different products or tenants need separate sending identities, PushMail has a first-class multi-site concept. Run newsletters.yourapp.com and alerts.yourapp.com from one account with separate contacts, templates, and API keys.
Resend doesn't have this model.
When to Choose Resend
- You only send transactional email and have no plans to add marketing
- You want the cheapest option available
- You want native React Email integration
- You don't need sequences, campaigns, contact management, or provider flexibility
- You're early and want to stay on the free tier as long as possible
Resend is excellent at what it does. If your requirements fit within that scope, use it.
When to Choose PushMail
- You need transactional and marketing email from one platform
- You want drip sequences with conversion goals
- You want to bring your own provider keys or support multiple providers
- You're building a multi-tenant product with separate sending identities
- You want email validation built in, not bolted on
- You want webhook events normalized across providers into a consistent schema
The Short Version
Resend is a modern transactional email API. It's clean, cheap, and well-built.
PushMail is what Resend would be if it added contact management, drip sequences, campaigns, multi-provider support, and email validation. Same developer-first philosophy, broader feature set, higher price.
If you've outgrown pure transactional email or you're building something that needs the full stack from day one, PushMail is worth a look.
