Resend pricing, plan by plan

Resend's transactional email pricing runs from a free plan ($0, 3,000 emails a month, capped at 100 a day) through Pro (from $20 a month for 50,000 emails) and Scale (from $90 a month for 100,000 emails) to custom Enterprise terms. Self-serve plans are billed monthly, and marketing email is priced separately by contacts. Everything below is from Resend's own pricing page and its account quotas doc, checked 8 Nov 2026.

We make Boundry, a competing transactional email API, so we include its prices for comparison and keep this page about Resend. Prices change, so check the linked page before you buy.

Transactional plans

• Free: $0 a month, 3,000 emails a month, 100 emails a day, 3 domains, 1 webhook endpoint, ticket support. No overage: pay-as-you-go is for paid plans only, so you are notified and offered an upgrade when you reach a limit.
• Pro: $20 a month for 50,000 emails, or $35 a month for 100,000 emails. No daily limit, 10 domains, 5 webhook endpoints, overage at $0.90 per 1,000 emails, ticket support with deliverability expertise, no Slack support.
• Scale: $90 a month for 100,000 emails, then $160 for 200,000, $350 for 500,000, $650 for 1,000,000, $825 for 1,500,000 and $1,150 for 2,500,000. 1,000 domains, 10 webhook endpoints, Slack support and an urgent response SLA. Overage per 1,000 emails falls from $0.90 at 100,000 to $0.80 at 200,000, $0.70 at 500,000, $0.65 at 1,000,000, $0.52 at 1,500,000 and $0.46 at 2,500,000.
• Enterprise: custom volume and price, a dedicated customer success manager and guaranteed response times. Retention is listed as flexible.

Message retention is listed as 30 days on Free, Pro and Scale.

The free plan and its daily cap

The free plan is 3,000 emails a month, but the page also lists a limit of 100 emails a day. A project that sends 3,000 emails in one burst, for example a launch announcement to existing users, reaches the daily cap long before the monthly one. For steady low volume, such as sign-up and password reset emails for a small app, 100 a day is often enough. For anything above that, the first paid step is Pro at $20 a month.

What it costs at 10k, 50k, 100k and 500k emails a month

These monthly plan prices cover each volume and exclude add-ons. The Resend plan is the one that covers the volume, not a quote. The Boundry figures use our Developer ($25, 50,000 emails) and Business ($250, 500,000 emails) plans, at the volumes they include.

• 10,000 emails a month: Resend Pro at $20 a month (Free cannot carry it, with 3,000 a month and 100 a day). Boundry Developer at $25 a month.
• 50,000 emails a month: Resend Pro at $20 a month. Boundry Developer at $25 a month.
• 100,000 emails a month: Resend Pro at $35 a month, or Scale at $90 a month if you need its higher domain count, Slack support and response SLA.
• 500,000 emails a month: Resend Scale at $350 a month. Boundry Business at $250 a month.

Between plan sizes you can stay on a smaller paid plan and pay overage instead. Overage is off until a team admin turns on transactional pay-as-you-go on the Usage page; while it is off, sending stops at the monthly quota until the next billing cycle. Overage sending is also capped by an overage limit, 400% of the monthly quota by default, which a team admin can set from 100% to 1,000%. Overages are billed in buckets of 1,000 emails, at $0.90 per 1,000 on Pro. Compare that with the next plan up before choosing, because at some volumes the larger plan is the lower total.

Add-ons and metered extras

• Additional domains: $20 a month for 100 more, on Pro and Scale.
• Dedicated IPs: $30 a month on Scale, listed for senders of more than 3,000 emails a day.
• SSO: $150 a month on Scale.
• Automation runs: 10,000 a month included on every plan. Paid plans then pay $0.0015 per run; Free has no overage.
• Inboxes: 3 included on every plan, then $1 per inbox a month on paid plans with pay-as-you-go.

Marketing plans are priced by contacts

Resend lists a separate marketing price table. Free covers 1,000 contacts. Pro marketing starts at $40 a month for 5,000 contacts and rises to $650 a month for 150,000 contacts, with Enterprise on custom terms. Marketing plans are limited by contacts, not emails sent, and broadcasts count against contacts rather than the transactional quota. If you only send transactional email, you only need the transactional plans above.

Billing and discounts

• The page says self-serve plans are billed monthly only. There are no annual plans and no annual discount; for an annual commitment at high volume, Resend points you to sales.
• Registered nonprofits can apply for 50% off paid plans.

Who each plan suits

• Free suits a prototype or a small app with steady low volume, under 100 emails a day.
• Pro suits a product in production that sends up to 100,000 emails a month and wants no daily limit.
• Scale suits teams sending from many domains, or those who want Slack support and a response SLA, or a dedicated IP at higher daily volume.
• Enterprise suits contracted volume, custom retention and a dedicated contact.

Boundry, for comparison

Boundry is a regional transactional email API. Plans are Sandbox ($0, 3,000 emails a month, 1 sending domain), Developer ($25 a month, 50,000 emails, 10 sending domains) and Business ($250 a month, 500,000 emails with graduated usage pricing up to 2 million, 1,000 sending domains), plus Enterprise on custom terms, all in US dollars. Each project is permanently bound to one region, and Sydney is the only live region today.

Boundry is not the right pick if you need a region other than Sydney now, or if you need to pay by card today, because paid checkout is not yet self-serve. We publish no deliverability rates or uptime figures. If you only need the lowest price at 50,000 emails a month, Resend's Pro plan is listed at $20 against our $25.
