We read that on 2026-11-02 from https://resend.com/pricing, and our check recorded: the page names Resend as "resend" and states "3,000 emails sent per day" and "3,000 emails / mo".
Until you verify a domain, Resend sends only from its resend.dev test domain, and only to the email address on your Resend account; mail to anyone else is refused with a 403 error. (From resend.com/docs/knowledge-base/403-error-resend-dev-domain, read 2026-10-20.)
Resend's free plan needs no credit card. (From resend.com/agents, read 2026-10-23.)
Resend launched Inboxes on October 22, 2026. "An inbox sends and receives email at an address on one of your domains." Every plan includes 3 Inboxes. Inboxes can be used by agents to receive tasks and updates. (From resend.com/blog/announcing-inboxes, read 2026-11-06.)
Broadcasts sent through the /broadcasts API or the dashboard do not count against the 3,000 transactional emails a month. Marketing plans are limited by contacts, not email volume. Emails sent or received through an inbox count towards the transactional emails quota. (From resend.com/pricing, read 2026-11-06.)
The default API rate limit is 10 requests per second per team across all API keys. The limit can be increased for trusted senders upon request. (From resend.com/docs/api-reference/rate-limit, read 2026-11-06.)
The API rate limit is the same on every plan and does not change when upgrading. The Batch Email API sends up to 100 emails per request, counting as one request against the limit. (From resend.com/pricing, read 2026-11-06.)
The Free plan has a daily quota of 100 emails, reset at midnight UTC, not a rolling 24-hour window. Paid plans have no daily quota, only a monthly limit. (From resend.com/docs/api-reference/rate-limit, read 2026-11-06.)
The free tier now has a limit of 3,000 emails/month (100/day) and includes 3 domains. Previously 3K emails/month (100/day) and 1 domain. The free tier also includes ticket support, 10,000 automation runs, and 30-day data retention. Source ↗
