Overview

On pricing, useSend and Resend aren't the same kind of thing, which is the whole point. Resend is a hosted subscription — you pay a per-email tier and get zero-ops convenience. useSend is open-source software you run yourself, so your cost is a server plus Amazon SES usage. The question isn't "which is cheaper" in the abstract; it's where the break-even sits for your volume and how you value your time.

Two different cost models

Resend's model: a free tier, then per-email/monthly subscription tiers that rise with volume. You pay more as you send more, in exchange for nothing to host or maintain. useSend's model: free software + your hosting (a few dollars a month on a small box) + Amazon SES at fractions of a cent per email. At low volume the difference is small; at high volume useSend-on-SES gets dramatically cheaper because SES delivery is near-cost and there's no per-email subscription markup.

The trade is convenience vs ownership and cost. Resend buys you zero ops; useSend buys you near-cost delivery and control, at the price of running it and owning deliverability yourself.

  • Resend: hosted per-email subscription, zero ops
  • useSend: free software + server + SES (near-cost) — you run it
  • Low volume: similar; high volume: useSend far cheaper
  • Convenience vs ownership + cost

Where the break-even sits

Roughly: if you send little and value your time, Resend's convenience usually wins on total cost (your hours aren't free). As volume climbs, the fixed-ish cost of a useSend box plus near-cost SES undercuts a per-email subscription, and the gap widens with scale. The exact crossover depends on current pricing (which changes, so check both), but the shape is reliable: hosted is cheaper small, self-hosted is cheaper big.

There's also a workflow dimension: neither useSend nor Resend includes campaigns or a reply inbox. Mailbase adds that layer at a flat price — €5/month on your own useSend, or €9/month managed — so the workflow cost stays constant whichever sender you choose. See useSend vs Resend for the non-pricing comparison.

  • Low volume + value your time → Resend convenience wins
  • High volume → useSend-on-SES undercuts per-email subscriptions
  • Check current pricing — figures change, the shape doesn't
  • Workflow layer is a separate, flat cost either way

Common mistakes

  • Comparing headline price instead of total operating cost (seats, sending, workflow).
  • Paying for a broad suite when you only need the operating layer.
  • Ignoring per-seat or per-contact scaling costs that bite later.
  • Assuming self-hosted is free — server, SES, DNS, and monitoring still cost.

Questions

About this page.

Is useSend cheaper than Resend?
At higher volume, usually yes — useSend is free software on a cheap server plus near-cost Amazon SES, with no per-email subscription markup. At low volume Resend's hosted convenience often wins on total cost once you value your own time. The break-even depends on volume and current pricing.
What's the pricing difference between useSend and Resend?
Resend is a hosted subscription with per-email/monthly tiers and zero ops. useSend is open-source: you pay for a small server and Amazon SES usage (fractions of a cent per email) and run it yourself. One is convenience-priced, the other is near-cost-plus-your-time.
When does self-hosting useSend pay off over Resend?
As volume grows. The fixed-ish cost of a useSend box plus near-cost SES eventually undercuts a per-email subscription, and the gap widens with scale. Below that crossover, Resend's zero-ops convenience is usually the better deal once your time is counted.
Do useSend or Resend include campaigns and a reply inbox?
No — both are sending layers. For campaigns, a shared reply inbox, and analytics you add a workflow layer like Mailbase, which is flat-priced (€5/month on your own useSend, or €9/month managed) regardless of which sender you use.
