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 offers Email API and Marketing Campaigns under one account, plus enterprise features such as sub-user management, dedicated IPs, and ISP outreach. The two sending products are priced and upgraded separately.

SendGrid Email API 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.

SendGrid's Marketing Campaigns pricing is separate. The plan has to cover both the contacts you store and the marketing emails you send:

SendGrid's current trial terms also treat Email API and Marketing Campaigns as independent trials and upgrades.

Where SendGrid wins

• Scale and reliability: SendGrid processes billions of emails. If you're sending 500K+/month, the infrastructure is proven.
• One account for two email products: Teams can manage Email API and Marketing Campaigns in SendGrid, although each has its own plan and allowance.
• 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 transactional pricing

Dedicated IPs are available on Scale for $30/mo when you send more than 3,000 emails per day.

Resend's Marketing pricing is separate and based on stored contacts. Broadcast volume is not metered within the contact tier:

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 plan: Resend's contact-based marketing pricing sits alongside its transactional send plan. SendGrid also prices Marketing Campaigns separately.
• 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

Transactional, lifecycle, and marketing email all draw from the same Dreamlit send allowance. You do not add a contact-based marketing plan when the same users receive campaigns.

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 is different

• Native to Supabase and Postgres: Dreamlit is the complete email layer for product-led SaaS on Supabase and Postgres. If your customer and event data lives only in MySQL, MongoDB, or Firebase, an API-first provider will be easier to adopt.
• Workflow layer, not a raw send endpoint: Dreamlit builds and runs email workflows from database events. If all you need is a single email API call from code, Resend or SendGrid fit that narrow job.
• Built around workflow ownership: Resend has React Email with 1.35M weekly downloads. SendGrid has 15 years of integrations and community resources. Dreamlit focuses on prompt-built workflows, live database previews, and letting non-engineers own email without SDKs or template code.

How the billing models change the comparison

A single "emails per month" chart only answers the transactional-only question. It leaves out the extra dimension that matters for marketing: how many contacts receive each campaign.

Transactional-only pricing

This table compares monthly plans for API or transactional sending only. It excludes Resend Marketing, SendGrid Marketing Campaigns, and Dreamlit annual discounts.

*SendGrid's free trial lasts 60 days at 100 emails per day. The table shows the paid price after the trial.

Pricing compared

Transactional-only monthly price by volume

• SendGrid
• Resend
• Dreamlit

Transactional-only monthly price by volume

Item	SendGrid	Resend	Dreamlit
10K emails	$19.95/mo	$20/mo	$20/mo
30K emails	$19.95/mo	$20/mo	$20/mo
50K emails	$19.95/mo	$20/mo	$99/mo
100K emails	$34.95/mo	$35/mo	$99/mo

On raw transactional price, Resend and SendGrid are the better value at 50,000 and 100,000 sends. Dreamlit costs more at 100,000 because the plan also includes its database-driven workflow layer, AI builder, and a shared allowance for other email types.

Mixed transactional and marketing workloads

Now add a contact list and campaign frequency. The table below uses monthly billing and plans whose included allowances cover the stated workload without overages.

Pricing compared

Mixed transactional and marketing workload

• SendGrid
• Resend
• Dreamlit

Monthly prices for mixed transactional and marketing workloads

Scenario	SendGrid	Resend	Dreamlit
Starter	$34.95	$20	$20
Growth	$69.95	$100	$99
Big list, low frequency	$139.95	$200	$99
Small list, high frequency	$69.95	$60	$99

For reproducibility, the SendGrid totals combine Essentials 50K with Marketing Basic 5K, Basic 20K, Basic 50K, and Basic 20K respectively. The Resend totals combine transactional Pro with Free Marketing, Pro Marketing 10K, Pro Marketing 25K, and Pro Marketing 5K respectively. Dreamlit uses Pro for Starter and Scale for the other three.

The mixed comparison has no universal winner:

• Dreamlit wins this big-list, low-frequency example because one shared allowance covers every send without a separate contact charge.
• Resend wins this small-list, high-frequency example because its marketing plan is contact-based and includes unlimited broadcasts.
• SendGrid wins this growth example on listed plan price, even after combining Email API and Marketing Campaigns.
• Resend and SendGrid win the raw transactional-only comparison at 50,000 and 100,000 sends.

These are pricing examples, not a deliverability claim. Your actual bill can change with contact storage, campaign frequency, overages, annual billing, or feature requirements. SendGrid's $89.95 Pro and Resend's $90 Scale plans add higher-tier features; neither is required just to cover 100,000 transactional emails.

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 want Email API and Marketing Campaigns managed under one account and are comfortable with separate plans
• 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 building product-led SaaS on Supabase or Postgres and want a complete email layer 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

Choose by architecture, not all at once. Use Dreamlit when email should react to your product database and be owned in one workflow system; use an API provider when code should make a one-off send call directly. And you don't have to pick just one on day one: keep existing API sends running, start your next workflow in Dreamlit, and consolidate as it proves itself. They operate at different layers, so nothing conflicts.

Frequently asked questions

Is Resend better than SendGrid?

It depends on the workload. Resend offers a clean API, strong docs, React Email support, and permanent free tiers for transactional email and small marketing lists. SendGrid offers both Email API and Marketing Campaigns under one account, but they are separately priced products.

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?

For 100,000 transactional emails, SendGrid Essentials ($34.95) and Resend Pro ($35) cost almost the same. Marketing changes the comparison: Resend prices marketing by contacts, while SendGrid uses a separate Marketing Campaigns plan based on contacts and included marketing sends.

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 3,000-email free tiers. Dreamlit becomes more relevant when transactional, lifecycle, and marketing email should share one allowance and one workflow system.

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).
