Cheap Email Marketing Tools for Developers
The genuinely cheap email marketing options for developers — Amazon SES, self-hosted useSend, free tiers, and where the real costs hide — plus how to keep costs low as you scale.

Overview
"Cheap" in email depends entirely on what scales your bill — and the trap is that the headline price isn't it. Per-contact marketing suites get expensive as your list grows; per-email APIs get expensive at volume; self-hosted is cheapest at scale but costs your time. For a developer, the cheapest real setup is usually Amazon SES underneath (fractions of a cent per email) with a thin layer on top. Here's the honest map.
The cheapest options, by model
Cheapest delivery: Amazon SES — pay-as-you-go at fractions of a cent per email, no per-contact charge. To make it usable, put self-hosted useSend on top (open-source, runs on a cheap Coolify/Railway/VPS box). Free to start: most APIs and ESPs have free tiers, and Mailbase has a free plan (200 emails/month) for the full workflow. Watch the model that bites you: per-contact (Mailchimp, MailerLite) climbs with list size even if you rarely send; per-email (hosted APIs) climbs with volume.
The genuinely cheap developer stack: SES + useSend for delivery (near-cost), plus a workflow layer only when you need campaigns and replies. Mailbase's BYO useSend plan is €5/month for that layer, or €9/month managed if you don't want to host — far below per-contact suite pricing at any real list size.
- Cheapest delivery: Amazon SES (cents/1k, no per-contact fee)
- Make it usable: self-hosted useSend on a cheap box
- Free to start: API/ESP free tiers + Mailbase free 200/mo
- Beware per-contact pricing — it climbs even when idle
| Option | Pricing model | Cheapest when |
|---|---|---|
| Amazon SES (+useSend) | Pay-as-you-go per email | You'll run the layer / high volume |
| Hosted API (Resend etc.) | Per-email tiers | Low/medium volume, want zero ops |
| Per-contact suite | Per contact + sends | Small list, want all-in-one |
| Mailbase | Flat (free/€5 BYO/€9) | You want workflow without per-contact pricing |
Where the real cost hides
"Cheap" tools aren't free to operate. Self-hosted costs a server, SES usage, and your time on deliverability and maintenance — see self-hosted email marketing costs. Free tiers cap volume and gate features (verification, seats). And per-seat or per-contact pricing on suites can balloon as the team or list grows, which is the cost that surprises people.
Optimize for total cost at your real volume, not the sticker price: a free tier now, SES + useSend when volume makes the math favor it, and a flat-priced workflow layer so seats and contacts don't multiply your bill. More in email marketing costs for SaaS and useSend vs Resend pricing.
- Self-hosted: server + SES + your time (not zero)
- Free tiers: capped volume, gated features
- Suites: per-seat/per-contact creep as you grow
- Optimize total cost at real volume, not sticker price
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.
