by ResendTransactional email APIs
Email API with a 3,000-email free plan, and a SOC 2 Type II report and pre-signed DPA on every plan.
A SOC 2 Type II report and a pre-signed GDPR DPA on every plan, with 3,000 free emails a month and 50,000 for $20.
Resend puts its compliance paperwork on every plan, including the free one: the security page says the SOC 2 Type II report and a DPA executed at sign-up are downloads under Settings → Documents. That answers a customer's security questionnaire without a sales call. Pricing is the lowest of the three at 50,000 emails a month.

Review from public pages
Written from Resend's public pages (pricing, security or privacy, and docs) as read on Oct 15, 2026. We did not sign up, and no hands-on run is published yet.
We read Resend's pricing, security and documentation pages on Oct 15, 2026; we did not sign up for this review. The docs list two things before the first send: a domain verified with Resend and an API key. Quickstarts cover 14 environments, from Node.js and Next.js to Rust, Elixir, .NET and a CLI.
The security page is unusually direct. It names the SOC 2 Type II audit, says the report and a pre-signed DPA sit under Settings → Documents, and states what Resend does not do: it is not HIPAA compliant, cannot sign a Business Associate Agreement, and does not sign country-specific DPAs. It also explains that choosing an EU region for a domain changes where mail is sent from, not where data is stored, which stays in the United States.
The pricing page separates transactional plans, priced by emails sent, from marketing plans, priced by contacts. Self-serve billing is monthly only.
SOC 2 Type II and GDPR are listed on every plan, and the report and DPA are self-serve downloads.
vs Postmark: Postmark says it has not had its own SOC audit; it offers its data center’s SOC 2 report under NDA.
Pro covers 50,000 emails a month for $20 with no daily cap.
vs Mailgun: Mailgun’s 50,000-email Foundation plan is $35 a month after a one-month free trial.
The security page states no HIPAA, no BAA, no country-specific DPAs and US data storage, so a compliance review has its answers without a ticket.
Fourteen quickstarts in the docs, including Rust, Elixir, .NET and a CLI.
Resend is not HIPAA compliant and cannot sign a Business Associate Agreement.
An EU sending region changes where mail leaves from; stored data remains in the United States under Standard Contractual Clauses.
Workaround: If you need EU sending infrastructure, Mailgun offers US and EU regions from one account.
The 3,000 free emails a month come with a limit of 100 per day, which suits testing more than production.
SSO is $150/mo on Scale and included only on Enterprise.
Transactional plans are priced by emails sent per month. Free covers 3,000 (100 a day). Pro is $20 for 50,000 or $35 for 100,000, with 10 domains and $0.90 per 1,000 beyond the plan. Scale runs from $90 for 100,000 to $1,150 for 2.5 million, with overage falling to $0.46 per 1,000, 1,000 domains and Slack support.
Add-ons are where the bill grows: a dedicated IP is $30/mo (for senders above 3,000 a day) and SSO $150/mo, both on Scale. Billing is monthly only; annual terms go through sales. Marketing email is a separate plan priced by contacts.
From its public pages, Resend is the cheapest way here to send 50,000 emails a month and the easiest to clear a security review with. Check the data-residency and HIPAA limits first.
