# Resend vs SendGrid

## Resend vs SendGrid

> Neutral head-to-head for developers comparing Resend and SendGrid. Unitpost appears only under an explicit disclosure. Facts verified on 2026-07.

### Resend

A developer-first transactional email API, known for the cleanest DX in the category and for React Email.

**Free tier:** 3,000 emails/month

**Pricing shape:** Transactional priced per volume, with Marketing (audiences + broadcasts) billed separately by contact count — so a team doing both pays on two axes.

**Strongest at:**

- The API shape and error semantics that set the modern standard — we deliberately match them
- React Email is the de-facto way to build email in React, and Resend maintains it
- A permanent free tier at the same 3,000 emails/month we offer
- Broad SDK coverage, including Go, PHP, and Elixir, which we do not have yet

### SendGrid

The Twilio-owned incumbent, processing billions of emails a month across transactional and marketing with deep enterprise tooling.

**Free tier:** None — a 60-day trial at 100 emails/day, then a paid plan (their free tier was retired in 2025)

**Pricing shape:** Monthly plans by volume, competitive at high throughput, with marketing contacts and add-ons like email validation billed separately.

**Strongest at:**

- Proven at a scale we have not operated at, with enterprise support to match
- The broadest integration catalogue in the category
- Sub-account management for multi-tenant platforms, which we do not offer
- Advanced IP management and dedicated IP pools for high-volume senders
