Resend and SendGrid solve the same problem, sending transactional email reliably, from two different eras of developer tooling. Resend was incorporated in January 2023, built by developers who had just open-sourced React Email a month earlier and wanted an API that felt as modern as the templating library it was paired with. SendGrid has spent over a decade building out marketing automation, dedicated IP management, and enterprise support on top of its core Email API, and Twilio’s acquisition only deepened that. If you’re shipping a Next.js or Node app and want the shortest path from a React component to a sent email, Resend is the faster build. If you need dedicated-IP reputation tooling, subuser management, or a marketing product in the same account, SendGrid’s broader platform is worth the heavier setup.
Where the Two Platforms Actually Diverge
The clearest way to see the difference is the origin story. According to Resend’s own account of its founding, the team started building what became Resend as a side project in August 2022, then launched React Email as an open-source project that December because they were frustrated with how hard it was to build email templates that rendered correctly across clients. React Email’s traction is what validated the broader platform; the API came second. SendGrid’s history runs the other way: the API and infrastructure came first, founded in 2009, and marketing tooling, dedicated IP management, and enterprise features were layered on over more than a decade as the platform grew and was acquired by Twilio in 2019.
That history shows up directly in how each product feels to integrate. Resend’s documentation leads with framework-specific quickstarts (Next.js, Express, Laravel, Rails) alongside language SDKs for Node.js, Python, Ruby, Go, Rust, Elixir, Java, and .NET, so a React or Next.js team can go from install to a sent email in a handful of lines. SendGrid’s official libraries cover seven languages, C#, Go, Java, Node.js, PHP, Python, and Ruby, but none of them are React-aware, and the dashboard reflects a decade of accumulated features (subuser management, IP pools, Marketing Campaigns) that a team sending nothing but transactional email will mostly never touch.
Side-by-Side Comparison
| Dimension | Resend | SendGrid |
|---|---|---|
| Developer experience | Minimal REST API with framework quickstarts for Next.js, Express, Laravel, Rails | Mature, full-featured API; larger dashboard and steeper initial setup |
| Official SDKs | Node.js, Python, Ruby, Go, Rust, Elixir, Java, .NET, plus framework-specific quickstarts | C#, Go, Java, Node.js, PHP, Python, Ruby (7 languages) |
| React Email | Built and maintained by Resend; supported on every tier, including Free | Not supported natively; React Email renders to plain HTML, so it can be sent through SendGrid’s API, but there’s no dashboard-level integration |
| Templates | Code-first: React Email components or raw HTML via the API | Dynamic Templates: a visual editor with conditional logic, available from the free trial up |
| Deliverability infrastructure | Shared IP pool by default; dedicated IP is a $30/mo add-on, restricted to Scale-plan accounts sending over 3,000 emails/day | Shared IP pool on Essentials; 1 dedicated IP included starting on Pro ($89.95/mo), plus subuser management and SSO |
| Free tier | 3,000 emails/month, permanent, capped at 100/day | 60-day trial only, 100 emails/day; no permanent free plan |
| Entry paid pricing | $20/mo for 50,000 emails (Pro) | $19.95/mo for 50,000 emails (Essentials) |

Pricing, as of July 2026
At the entry paid tier, the two are nearly identical: Resend’s Pro plan runs $20/month for 50,000 emails, and SendGrid’s Essentials plan runs $19.95/month for the same volume, with a $34.95/month step up to 100,000. Where they split is the free tier. Resend’s Free plan gives 3,000 emails a month with no expiration date, useful for a side project or a staging environment that never graduates to a paid plan. SendGrid retired its permanent free plan in 2025 and replaced it with a 60-day trial capped at 100 emails a day; once the trial ends, you’re on a paid plan or nothing.
At higher volume the comparison gets more granular. Resend’s Scale plan runs from $90/month (100,000 emails) up to $1,150/month (2,500,000 emails), with the per-1,000-email overage rate dropping as volume rises. SendGrid’s Pro plan starts at $89.95/month for 100,000 emails and scales through $249, $499, and $799 tiers up to $1,099/month at 2,500,000 emails. Above that, both vendors move to custom Enterprise or Premier pricing.

Deliverability and Dedicated IPs
Both platforms handle standard transactional deliverability well once your sending domain has SPF, DKIM, and DMARC configured correctly; neither has a documented, independently verified deliverability edge over the other at typical SaaS transactional volumes. The infrastructure differs at the higher-volume edge. SendGrid includes one dedicated IP starting on its Pro plan, alongside subuser management and single sign-on, tooling built for teams managing sender reputation across multiple accounts or brands. Resend’s dedicated IP is a $30/month add-on, and it’s gated to Scale-plan customers sending more than 3,000 emails a day, a more recent addition to a platform that defaults to shared-pool sending.
Neither vendor publishes a specific volume threshold at which a dedicated IP becomes worth the cost; both simply restrict the feature to their higher tiers, which functions as a proxy for “we expect only high-volume senders to need this.” For most transactional workloads under six figures a month, a shared pool with correct authentication performs comparably to a dedicated IP on either platform.
Choose Resend If
- You’re building in React or Next.js and want React Email’s component model supported as a first-party feature, not bolted on
- You want a permanent free tier for side projects or early development, without a trial clock running
- Your team prefers a minimal API surface over a feature-dense dashboard
- You don’t yet need subuser management, SSO, or a bundled marketing product
Choose SendGrid If
- You need a dedicated IP, subuser management, and SSO included in a single mid-tier plan
- Your templates are already built with a visual editor and Handlebars-style logic, and rebuilding them as React components isn’t worth the switch
- You’re scaling toward millions of emails a month and want Twilio’s enterprise support tier behind you
- Your team is already in the Twilio ecosystem for SMS or voice and wants one vendor relationship

Frequently Asked Questions
Is Resend cheaper than SendGrid?
At the entry paid tier, they’re close to identical: Resend’s Pro plan is $20/month for 50,000 emails, versus $19.95/month on SendGrid’s Essentials plan for the same volume. Resend pulls ahead on the free tier, since its Free plan never expires, while SendGrid’s free option is a 60-day trial. At higher volumes, compare the specific tier you need directly, since both vendors’ pricing scales in steps rather than a flat per-email rate.
Does SendGrid support React Email?
Not natively. SendGrid’s official SDKs cover C#, Go, Java, Node.js, PHP, Python, and Ruby, none of them React-specific, and there’s no dashboard-level React Email integration. Because React Email renders down to plain HTML, you can technically build a template with it and send the resulting HTML through SendGrid’s API, but you’d be wiring that pipeline together yourself rather than using a supported integration.
Which has better deliverability, Resend or SendGrid?
For typical transactional volume, both perform comparably once domain authentication is set up correctly. SendGrid includes a dedicated IP starting on its Pro plan ($89.95/month) along with subuser management and SSO. Resend’s dedicated IP is a $30/month add-on available only to Scale-plan accounts sending over 3,000 emails a day. Neither vendor publishes independently verified deliverability benchmarks against the other.
Can I switch from SendGrid to Resend without much rework?
The send code itself is a modest rewrite either way, since both expose a REST API and official SDKs. The bigger lift is templates: SendGrid’s Dynamic Templates, built with its visual editor, don’t import directly into Resend, so you’d rebuild them as React Email components or raw HTML. You’ll also need to reconfigure SPF and DKIM records for Resend’s sending domains before cutting traffic over.
Does Resend have a permanent free tier?
Yes. Resend’s Free plan includes 3,000 emails a month, capped at 100 a day, on one domain, with no expiration date, per Resend’s pricing page as of July 2026. That’s a real difference from SendGrid, which retired its permanent free plan in 2025 in favor of a 60-day trial.
When does a dedicated IP make sense on Resend or SendGrid?
A dedicated IP generally earns its cost once sending volume is high and consistent enough to build its own sender reputation rather than riding on a shared pool’s. Both vendors gate the feature to their higher tiers, Scale on Resend and Pro on SendGrid, for exactly this reason: below that volume, a well-authenticated shared pool typically performs just as well and costs less.
