Resend vs SendGrid

If you are choosing between Resend and SendGrid for transactional email, price will not decide it for you at low volume: at 50k and 100k emails a month they cost within a few cents of each other (as of October 2026). The real differences are developer experience, the free tier, dedicated IPs and how much of a platform you want. Resend is the newer, focused, developer-first tool. SendGrid, owned by Twilio, is the older and broader one.

Below is a side-by-side comparison, then a use-case guide, then a short note on a third option: running your own mail server.

All prices here are as of October 2026, taken from third-party pricing trackers. Plans change often, so confirm on Resend's pricing page and SendGrid's pricing page before you commit.

Resend vs SendGrid at a glance

How much do Resend and SendGrid cost at different volumes?

At the bottom of the range they are effectively the same price. Resend Pro is $20 for 50k emails and $35 for 100k; SendGrid Essentials is $19.95 and $34.95. If all you need is a few tens of thousands of password resets and receipts a month, the bill will not be the deciding factor.

Things diverge once you need more than the entry plans:

• At 100k with a dedicated IP, SendGrid Pro starts at $89.95 and includes the IP. Resend's Scale tier is $90 at 100k; check their pricing page for what it includes on IPs.
• At 200k–500k, Resend Scale runs $160 (200k) and $350 (500k). SendGrid's published Pro tiers in our sources are around $249 for 300k. Compare the exact tier you would land on, not the headline price.
• At 2.5M, both top out around $1,100–1,150 a month before custom enterprise pricing (SendGrid Premier above 2.5M is custom).

Free tier: ongoing plan vs trial

Resend's free plan is ongoing: 3,000 emails a month with a 100-per-day cap. That is enough for a side project, a staging environment, or a small app's sign-up and reset emails.

SendGrid's free option is a trial: 100 emails a day for 60 days. It is useful for evaluating the product, but it is not a long-term home for a hobby project.

Dedicated IP and shared reputation

On the entry plans, both send from shared IPs. Your deliverability then depends partly on the other senders on those IPs, which the provider manages. For most small transactional streams, this is fine and often better than a cold dedicated IP.

SendGrid includes a dedicated IP on Pro (from $89.95/month). That is a clear, published path if you know you want one. For Resend, dedicated IP options were not in our sources, so check their pricing page. Either way, a new dedicated IP needs warm-up and steady volume. Our post on shared vs dedicated IPs covers when one is worth it.

Inbound email

If you need to receive and process email (replies to support tickets, email-to-app features), SendGrid has long offered Inbound Parse, which posts incoming messages to a webhook. For Resend, check their documentation for current inbound support rather than relying on a comparison page, ours included.

Developer experience

This is where most people actually decide.

Resend is built around a small, modern API and React Email, so you can write templates as React components. Teams on Next.js or other TypeScript stacks often find it quick to adopt. It was historically built on Amazon SES and raised an $18M Series A led by Andreessen Horowitz in December 2024, so it is a young but funded company.

SendGrid has been around much longer and covers more: transactional sending, marketing campaigns, templates, inbound parsing, and a large dashboard. That breadth means more settings to learn, but also fewer reasons to add a second tool later. Both offer SMTP as well as an HTTP API, so you are not locked into a specific SDK.

Marketing email

Neither bundles marketing email into the transactional price. Resend bills marketing by contacts (around $40/month for 5k contacts), and SendGrid's Marketing Campaigns are priced separately (from around $15/month), as of October 2026. If newsletters matter, price both products together.

Which should you choose?

Choose Resend if:

• You are a developer-led team on a modern JavaScript/TypeScript stack.
• You want to build templates in React Email.
• You are small and want an ongoing free tier for staging or a side project.
• You value a smaller, simpler API over a big feature set.

Choose SendGrid if:

• You want a published plan that includes a dedicated IP (Pro).
• You need inbound parsing today from the same vendor.
• You want transactional and marketing email from one long-established provider.
• Your organisation already uses Twilio.

It probably doesn't matter if: you send under 100k transactional emails a month from shared IPs. Pick the one whose API your team prefers and spend the effort on getting SPF, DKIM and DMARC right. That matters more for inbox placement than the provider name.

A third option: run your own mail server

Some teams compare Resend and SendGrid and then realise they would rather not rent sending at all. A self-hosted server (Postfix with DKIM, TLS and proper DNS on a VPS you control) has no per-email fees, gives you your own IP, and keeps your mail data on your own machine.

To be plain about the trade-off: it is not cheaper at small volume. Up to about 100k emails a month, Resend and SendGrid cost $20–35, while a managed self-hosted server is around $99/month plus a VPS (typically about $5–20/month). Self-hosting tends to win on cost roughly above 200k emails a month, and on control, privacy and running many domains at any volume. You also take on warm-up, monitoring and updates, or pay someone to.

We compare this honestly in self-hosted email vs Resend, and the step-by-step Postfix guide shows exactly what is involved.
