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 |
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.

FAQ
What's the cheapest email marketing tool for developers?
At scale, Amazon SES (fractions of a cent per email) via self-hosted useSend on a cheap box is the cheapest, with no per-contact charge. To start, free tiers work — including Mailbase's free 200 emails/month. Add a flat-priced workflow layer instead of a per-contact suite as you grow.
Why is per-contact email pricing expensive?
Per-contact pricing (common in marketing suites like Mailchimp and MailerLite) charges for the size of your list whether or not you email it, so the bill climbs as you grow even if sending volume stays flat. Per-email and flat-priced models avoid that for many senders.
Is self-hosted email actually cheaper?
At volume, usually yes — near-cost SES delivery beats per-contact suite pricing — but it isn't free: you pay for a server, SES usage, and your own time on deliverability and maintenance. It's cheapest when you already run infrastructure or send enough to justify the setup.
What's the cheapest way to add campaigns and a reply inbox?
A flat-priced workflow layer rather than a per-contact suite. Mailbase is €5/month on bring-your-own useSend (delivery on your own infra) or €9/month managed, which stays cheap regardless of list size — versus suites that charge per contact or seat.
