Migrating from another provider?

Switching means moving your send call to POST /v1/send (see the migration guide). Claim 50% off your first 3 months when moving from a paid Resend, Postmark, Mailgun, SendGrid, or AhaSend account. After approval, the discount applies automatically at Checkout — no promo code to enter. We also help with DNS, DKIM rotation, and OTLP wiring, and answer security reviews with the procurement pack. (Offer does not apply to infrastructure-only providers such as Amazon SES.)

Quota model

Each accepted recipient counts as one message. Dashboard warning at 80% of included volume. Paid plans bill overage until a hard stop at 150%, then 429 quota_exceeded. A workspace can set a lower monthly cap to limit its overage spend; past it, sends return 429 spending_cap_reached. Each forwarded inbound message also counts as one message; at either limit, forwards are retried for up to a day, then returned to the sender. No daily caps — scale within your monthly allowance.

Enterprise

Enterprise is not a self-serve checkout. Tell us the volume, SLA, domains, dedicated IPs, or procurement you need — we quote a contract that fits. Email info@blindrelay.app to start.

CLI / Agent Plugin send	CLI · Agent Plugin send tools on every plan
Gmail Send-as / SMTP	Mini+ — Gmail Send-as, plus Apple Mail, Outlook, Thunderbird, and other SMTP clients; same quota pool as REST (SMTP: 1 unit per started MB). Setup guide
Dedicated IP	Add-on on every paid plan (€12/mo each, as many as you need, excl. VAT) — isolated reputation (during warmup, mail above the daily limit uses the shared pool), own delivery worker, forwarding inbound mail to a mailbox. Why a dedicated IP
