Resend vs SendGrid in 2026: What the Comparisons Leave Out

If you're shopping for a transactional email API, Resend and SendGrid are probably the two names on your list. SendGrid's been around since 2009 but feels its age. Resend is the modern alternative, but it's still a developer tool: API keys, React templates, code in your app.

Then there's a third option that works differently from both: no API, no code, and anyone on your team can use it.

SendGrid

SendGrid has been a default transactional email API service since Twilio acquired it in 2019. It handles both transactional and marketing email, offers SMTP relay and a REST API, and has the enterprise features (sub-user management, dedicated IPs, ISP outreach) that come with 15+ years in the space.

SendGrid pricing

Dedicated IPs start at the Pro tier ($89.95/mo). The permanent free plan was retired on May 27, 2025. New direct accounts get a 60-day trial, then you're on a paid plan.

Where SendGrid wins

• Scale and reliability: SendGrid processes billions of emails. If you're sending 500K+/month, the infrastructure is proven.
• Marketing and transactional in one: One of the few platforms that handles both under one roof. No second tool needed.
• Enterprise features: Sub-user management, IP warmup tools, ISP outreach, and dedicated IPs on Pro.
• SMTP relay: If you just need to swap SMTP credentials, SendGrid makes it simple.

Where SendGrid falls short

• No permanent free tier for new direct signups: You get 60 days, then it's $19.95/mo minimum.
• The whole experience feels antiquated: The dashboard, the docs, the SDK patterns. Compared to Resend or Dreamlit, using SendGrid is like stepping back in time.
• Shared IP deliverability issues: Lower-tier plans share IPs with other senders. If your neighbors spam, your deliverability suffers.
• Twilio ownership concerns: Since the acquisition, the product has shifted toward enterprise pricing. Smaller senders have felt the squeeze.

Resend

Resend is a modern email sending API built by the team behind React Email. If you're building with React or Next.js, Resend lets you write email templates as JSX components instead of wrestling with table-based HTML. It's quickly become the go-to for developers who want a clean API and fast integration.

Resend pricing

Dedicated IPs are available on Scale ($30/mo, requires 500+ daily sends).

Where Resend wins

• Developer experience: The cleanest email API on the market. Great docs, intuitive SDK, fast integration.
• React Email ecosystem: Write templates as JSX components. The react-email package has ~1.35M weekly npm downloads as of February 2026. If you're in the React ecosystem, this is a real advantage.
• Modern API design: Resend's API feels like it was built in 2024, because it was. SendGrid's feels like it was built in 2012, because it was.
• Generous free tier: 3,000 emails/month permanently, capped at 100/day (not a trial). Enough to get a side project into production.

Where Resend falls short

• Free tier still has limits: 100/day cap and 1 domain on Free. Fine for a side project, restrictive once you need more senders or environments.
• Marketing email is a separate product: Resend's broadcast pricing is separate from its transactional API plans. SendGrid bundles marketing and transactional together.
• Overage adds up fast: $0.90 per 1,000 emails is 9x more than Amazon SES ($0.10/1K). At high volume, this matters.
• Built for developers, not everyone: Resend is a great developer tool, but that's exactly what it is: a developer tool. You're still managing API keys, writing send logic in code, and building templates in JSX. If you're not a developer (or don't want to spend your time on email plumbing), there's a learning curve.

What if you didn't need an email API at all?

Your database already knows when a user signed up, when they made a purchase, and when they haven't logged in for a week. Why write code to tell an external service what your database already knows?

That's the question we started with when we built Dreamlit.

Dreamlit

Dreamlit securely connects to your Postgres database and reacts to changes. When something happens (a new row, an updated field, a status change), Dreamlit triggers workflows automatically. Describe what you want in plain English, and the Workflow Agent generates the trigger logic, email template, and copy.

No API keys. No webhooks. No email code in your app.

Dreamlit pricing

Dreamlit's public pricing page defaults to annual billing, so the lower $16/mo and $79/mo figures are annual-billing equivalents rather than month-to-month rates.

Where Dreamlit wins

• Anyone can use it: You don't need to be a developer. Describe what you want in plain English, and the Workflow Agent handles the rest. No API keys, no React, no code.
• Database-driven architecture: Your Postgres database is the source of truth. Data changes are the triggers. No syncing, no webhooks, no keeping two systems in agreement.
• AI does the work: Tell the Workflow Agent "send a welcome email when someone signs up" and it generates the trigger logic, email template, and copy. Iterate by chatting, not by writing code.
• Non-engineers can own email: Your marketing person, your ops lead, your co-founder who doesn't code. They can build and manage entire email workflows themselves. On a lean team, that means email doesn't sit in the engineering backlog.
• Annual billing can be competitive: Pro is $20/mo month-to-month or $16/mo billed yearly for 30K emails.

Where Dreamlit falls short

• Requires Postgres: Dreamlit connects to Postgres databases (including Supabase). If you're on MySQL, MongoDB, or Firebase, Resend or SendGrid are better options today.
• No standalone API: If you need to call an email endpoint from code (like sending a receipt triggered by a Stripe webhook that doesn't touch your database), a traditional email API is a better fit for that flow.
• Younger ecosystem: Resend has React Email with 1.35M weekly downloads. SendGrid has 15 years of integrations and community resources. Dreamlit is newer, and we're earlier in that journey.
• Supabase/Postgres-centric: Our deepest integration is with Supabase. If you're not in the Postgres ecosystem, you won't get the full benefit.

Pricing comparison at different volumes

What you'd pay per month at each sending volume:

*SendGrid's free trial lasts 60 days (100 emails/day), then the minimum paid plan is $19.95/mo.

Dreamlit figures show month-to-month pricing first, with yearly-effective pricing in parentheses.

Where each provider wins on price:

• Resend is the cheapest way to start if you can stay inside its permanent free tier.
• At 10K-30K, SendGrid and Resend are roughly tied with Dreamlit on month-to-month pricing, while Dreamlit gets cheaper on annual billing.
• At 50K, Resend is cheaper than Dreamlit, because Dreamlit jumps to its 100K plan.
• At 100K, Resend is cheaper month-to-month ($90 vs. $99), but Dreamlit is cheaper on annual billing ($79 effective).

The pricing crossover point depends on whether you're comparing month-to-month or annual billing. Dreamlit looks meaningfully stronger on yearly pricing than it does on month-to-month pricing.

For raw cost per email at high volume, Amazon SES ($0.10/1K) beats all three.

How to choose the best email API for your project

Pick SendGrid if:

• You're sending at high volume (500K+/month) and need proven infrastructure
• You need marketing email and transactional email in one platform
• You need enterprise features like sub-user management and dedicated IPs
• You're migrating from another SMTP provider and want a simple relay swap

Pick Resend if:

• You're building with React or Next.js and want JSX email templates
• Developer experience is your top priority
• You want a clean, modern API (marketing emails available as a separate add-on)
• You're comfortable writing email code in your app and want the control that comes with it

Pick Dreamlit if:

• You're on Supabase or Postgres and want email workflows without writing email code
• You'd rather describe what you want in plain English than integrate an API
• You want your database to be the source of truth for when emails get sent
• You're a solo founder or small team that wants production-ready emails running in minutes, not hours

You don't have to pick just one. Keep your existing email provider for flows that already work. Use Dreamlit for new workflows where your database already has the data. They don't conflict because they operate at different layers.

Frequently asked questions

Is Resend better than SendGrid?

For many developers starting new projects, yes: Resend offers a cleaner API, strong docs, React Email support, and a permanent free tier. SendGrid still has strengths for high-volume enterprise use cases where marketing and transactional tooling are tightly integrated.

Is SendGrid still worth using in 2026?

It depends on your tier. SendGrid Pro with dedicated IPs can still be a strong option for high-volume transactional email, while lower tiers have more constraints like shared IPs and no permanent free plan.

How does Resend pricing compare to SendGrid pricing?

At low volume, Resend is often cheaper because it has a permanent free tier. At mid volume, both can be around $20 per month. At 100K emails, SendGrid Essentials can be cheaper than Resend Scale.

What's the cheapest transactional email API?

For raw per-email cost, Amazon SES is usually cheapest. In this three-way comparison, Resend and Dreamlit both offer permanent free tiers (3,000/mo). Dreamlit becomes more compelling if you want database-driven workflows or plan to use yearly billing.

Can I use Dreamlit without Supabase?

Yes. Dreamlit works with Postgres databases beyond Supabase. If you're not using Postgres, a traditional email API provider may be a better fit.

What's the difference between an email API and database-driven email?

With an email API, your application code decides when to send and calls the provider. With database-driven email, database changes trigger workflows directly, so less email orchestration logic lives in your app.

Do I need to choose one provider?

No. Teams often use multiple providers. You can keep existing API-based flows and add database-driven workflows where they fit best.

Which has the best email deliverability?

No provider guarantees inbox placement on its own. Deliverability depends heavily on domain reputation, sending behavior, list quality, and authentication setup (SPF, DKIM, DMARC).
