Resend vs SendGrid

Resend vs SendGrid: the short answer

Pick Resend if you're a solo developer or small team, especially on React or Next.js, and you want to send email from code with little setup. Pick SendGrid if you send at high volume, need dedicated IPs and warmup control, or already live in the Twilio ecosystem. For a first app, start with Resend.

What is Resend?

Resend is an email API built by the team behind React Email. You write templates as React components and send them, while deliverability, DKIM and SPF setup, and webhooks are handled for you.

What is SendGrid?

SendGrid, now Twilio SendGrid, is a large email delivery platform covering transactional email (API or SMTP) and marketing campaigns from one account. It has sent at enterprise volume for over a decade.

Resend vs SendGrid pricing

Pricing checked November 2026.

Resend:

• Free: $0, 3,000 emails per month, 100 per day, 3 domains, 30-day data retention.
• Pro: $20/mo, 50,000 emails, no daily limit, 10 domains.
• Scale: $90/mo, 100,000 emails, no daily limit, 1,000 domains.
• Custom: enterprise pricing.

SendGrid:

• Paid plans are priced by monthly send volume. We could not load a readable pricing page, so check the SendGrid pricing page for the free tier, plan names and numbers.

For a solo builder or small team, Resend is easier to cost out because every limit is published, including the 100 per day cap on the free plan. That cap matters if you send in bursts. Whether SendGrid ends up cheaper at high volume depends on its current plan numbers, so compare them against your monthly send count.

Key differences

• Setup: Resend has a small API surface and gets you sending quickly. SendGrid has a heavier dashboard and setup flow.
• Templates: Resend integrates React Email, so templates are JSX. SendGrid is not built around that workflow.
• Scale tooling: SendGrid offers dedicated IP options and IP warmup tooling. That matters at high volume.
• Scope: SendGrid covers transactional and marketing campaigns in one platform. Resend focuses on sending from code, with batch sending for newsletters and digests.
• Validation: SendGrid has an email validation API to catch bad addresses before they hurt sender reputation.
• Track record: SendGrid has been at it far longer and sits under Twilio, with enterprise support and compliance tooling.

When to pick Resend

• You build in React or Next.js and want templates as components.
• You're sending transactional email from a new app.
• You want published limits and a free plan that's easy to read.
• You don't need dedicated IPs yet.

When to pick SendGrid

• You send high volume and need IP warmup control.
• You want campaigns and transactional mail in one account.
• You already use Twilio.
• You want an email validation API built in.

Other options

If transactional mail is the whole job and you want it isolated from broadcast traffic, look at Postmark. For SaaS onboarding and lifecycle sequences with a visual builder, try Loops.

Verdict

Start with Resend. It gets a new app sending sooner and its free plan is clear. Move to SendGrid only when volume, IP control or an existing Twilio setup makes its heavier platform worth it.
