Usage-based pricing on infrastructure we run ourselves. A genuinely useful free tier, overage that drops as you scale, and white-label margin for resellers. Deliverability and compliance automation are bundled free at every tier.
For prototypes and the migration on-ramp.
For production apps sending real volume.
For high-volume senders who need reputation control.
For agencies and platforms reselling under their own brand.
Sourced from live competitor pricing pages (Jun 2026). We undercut on free-tier volume, entry price, overage, and dedicated IPs — while bundling the deliverability and compliance automation others gate or omit.
| Provider | Free tier | Entry plan | Overage / 1k | Dedicated IP / mo |
|---|---|---|---|---|
| usermails | 5,000 / mo | $18 → 60k | $0.70 | $20 |
| Resend | 3,000 / mo | $20 → 50k | $0.90 | $30 |
| Postmark | 100 / mo | $15 → 10k | $1.80 | from $50 |
| SendGrid | None (retired) | $19.95 → 50k | Tiered, opaque | $30 |
| Mailgun | ~3,000 / mo (100/day) | $15 → 10k | $1.80 | $59 |
Competitor figures read from vendor pricing pages, Jun 2026; SendGrid overage is not transparently published. Directional, not a quote.
Our marginal cost per email is near-zero — we run the sending infrastructure ourselves with dedicated IPs. We sell the control plane, deliverability outcomes, and brand, not bytes. So the things others charge premiums for, we include.
SPF/DKIM/DMARC setup, RFC 8058 one-click unsubscribe, and complaint-rate auto-suspension above ~0.3% — table-stakes under Google/Yahoo rules, never an add-on here.
$0.70/1k on Pro drops to $0.55 on Scale and $0.40/1k past 1M. The more you send, the less each email costs — winning customers stay.
Clear overage, usage alerts, and hard caps you set. The free tier is a real cap, not a trap. Anti-SendGrid by design.
It's a permanent tier: 5,000 emails/mo with the full Resend-compatible API, logs, signed webhooks, and DKIM/DMARC automation. It's a hard cap, not a billing trap — when you hit it, sends pause until next cycle or you upgrade. No card, no expiry.
Each paid plan includes a monthly volume; past that you pay per 1,000 emails at your plan's rate — $0.70/1k on Pro, $0.55/1k on Scale, dropping to $0.40/1k above 1M. White-label resellers get $0.30/1k wholesale and set their own client pricing. You can cap usage so a runaway loop can't run up a bill.
Once you're sending consistent volume, a dedicated IP gives you sole ownership of your sending reputation. It's a $20/mo add-on with managed warmup included — and it's bundled into Scale at no extra cost. Lower-volume senders are better off on warmed shared pools.
The API accepts Resend's payloads, so the resend SDK works with a single base-URL change — no rewrite. Start on Free to validate, then move volume to a paid plan when you're ready. Migration tooling and log parity are part of the wedge.
Create a key, point your SDK at usermails, and send your first 5,000 emails free — deliverability and compliance automation included.
