Transactional
Orders, password resets, OTP codes. A dedicated queue and Configuration Set — marketing spikes never slow it down.
Orders, password resets, OTP codes. A dedicated queue and Configuration Set — marketing spikes never slow it down.
Audience segments, Double Opt-in, forced unsubscribe links — compliance is the default, not an option.
Realtime callbacks for delivered / opened / bounced. HMAC signing, exponential backoff, auto circuit-breaking.
Instant doc answers, page jumps, confirm-then-execute. DeepSeek V4 Flash via OpenRouter, fully audited.
Every request gets an ID at the gateway, and every leg after that is traceable — queue depth, SES status, bounce reasons, all flowing back to logs and your webhooks. Nothing disappears silently.
Stop copy-pasting DNS records across two tabs. Authorize one Cloudflare Zone and the platform writes, merges and patrols for you — SPF is merged, never overwritten.
Every email has a traceable timeline — from gateway acceptance to inbox behaviour, all six event types leave a trail; filter by status and inspect the timeline in the console.
Transactional and marketing mail ride separate pools, with webhook retries as their own safety net. Drag the sliders and watch the wire respond — in production, these are three queues that never drag each other down.
REST API + webhooks, semantic error codes with a doc page each. From signup to first email in under a minute.
Sign up, verify a domain, paste three lines of code. Reputation, retries, bounces and compliance — that is the relay's job.
Get your API key →No. Sign up and start sending; when you outgrow the free tier, upgrade anytime and cancel anytime.
Authorize Cloudflare and DNS records are written automatically; other providers get a record list to add manually — we auto-detect them.
No. Separate queues and separate SES configuration sets keep reputations fully isolated.
Forced unsubscribe links, One-Click Unsubscribe, Double Opt-in and suppression lists are on by default and cannot be turned off.
A REST API today: the docs include cURL examples and every error code is documented. Official SDKs are on the roadmap.
Answer doc questions, jump you to the right console page, execute actions after your confirmation — fully audited.
A monthly fee plus a discounted rate: Free 5,000/mo; Pro $10/mo includes 31,250 emails, then $0.32 per 1k (20% off list); Platform $20/mo includes 100,000, then $0.20 per 1k (50% off). No daily caps — 20–70% below Resend at the same volume.
Self-serve upgrades in the console take effect immediately; cancel through the Stripe billing portal and keep sending until the period ends, then you return to Free (data kept for 30 days).
Event details 90 days, delivery records 30 days, idempotency keys 24 hours. Contacts export to CSV anytime.
Any domain or subdomain you own works (e.g. mail.yourdomain.com). DKIM, SPF and DMARC are configured and continuously checked — one-click via Cloudflare or manual DNS.
HTTPS everywhere, AES-256-GCM for sensitive fields, argon2id passwords, TOTP two-factor; enforced tenant isolation and audit trails on privileged actions; DPA available; data primarily in AWS us-east-1.
Every customer uses their own sending domain and reputation; exceeding 5% bounce or 0.1% complaint over 24h triggers automatic throttling and human review; new domains get warm-up protection; delivery, open, click and bounce events stream back in full.
