# Looking for a Kit (ConvertKit) alternative?

> Kit leads the creator economy but has no transactional email and prices per subscriber. Email Fast does newsletters and transactional in one platform.

Canonical: https://emailfast.dev/compare/kit-alternative

Kit earned its place: the creator-economy leader, a celebrity-creator brand, and a
genuinely thoughtful jobs-based product. The comparison is about scope and evidence.
Kit has no transactional email product at all, its developer surface stops at list
management, and where its marketing publishes a headline delivery-rate figure without
methodology, we'd rather hand you per-message proof — while admitting we have no live
history yet.

## The comparison

| | Kit | Email Fast |
|---|---|---|
| Transactional email | No transactional product | Included on every plan ([pricing](/pricing)) |
| Developer surface | List management only; no sending SDKs | SDKs for the browser (EmailJS-compatible), Node.js, Python, PHP, Go, and Ruby, plus a zero-dependency CLI and a published OpenAPI specification |
| Subscriber pricing | Free to 1,000 subscribers; Creator from $33/month, rising with list size | contacts and subscribers are never billed — we price sending, not the size of your audience |
| Commerce fees | 3.5% + 30¢ per transaction; paid recommendations take 23.5% | No commerce product; reader billing (via Stripe) opens with general availability |
| Delivery evidence | A headline delivery-rate figure published without methodology | delivered messages can mint an Ed25519-signed delivery certificate — receiving mail server, TLS details, the server's SMTP response, and timestamps, with the recipient stored only as a keyed hash — chained into a tamper-evident ledger and verifiable without trusting us |
| Security page | Cites AWS's and Cloudflare's audits rather than first-party certification | First-party and open, including the attestations we don't hold ([security](/security)) |

## Evidence over asserted numbers

Kit publishes a headline delivery-rate figure without methodology. We publish no
figure at all — no live history yet, and a number without a method is theater either
way. What we mint instead: delivered messages can mint an Ed25519-signed delivery certificate — receiving mail server, TLS details, the server's SMTP response, and timestamps, with the recipient stored only as a keyed hash — chained into a tamper-evident ledger and verifiable without trusting us.

## Where Kit is the right choice

- **You're a creator first.** The jobs-based product, the celebrity-creator brand, and the creator-economy ecosystem are the point — and Kit leads it.
- **Your list is under 1,000 subscribers.** Kit is free there.
- **You'll use their commerce and recommendations.** 3.5% + 30¢ and 23.5% are the published cost of a monetization stack that already works.

## Switching

Newsletters and transactional run on one platform here, so the migration is broader
than a list export — but the list export is where it starts, and
contacts and subscribers are never billed — we price sending, not the size of your audience. Start with a [sandbox key](/get-started):
sandbox keys (ef_sandbox_…) that run the real pipeline dry: real validation, real rendering, real events, a hosted capture inbox — and no email leaves. Live delivery opens at launch; reader billing opens with general
availability.

## Can Kit send transactional email?

No — their site offers no transactional product, and the developer surface is list management only, with no sending SDKs. Here transactional is on every plan, with SDKs for the browser (EmailJS-compatible), Node.js, Python, PHP, Go, and Ruby, plus a zero-dependency CLI and a published OpenAPI specification.

## What's wrong with a published delivery-rate figure?

Without methodology it can't be checked: what was measured, over what mail, in what period. We publish no figure at all — we have no live history yet and say so. The alternative is per-message evidence: delivered messages can mint an Ed25519-signed delivery certificate — receiving mail server, TLS details, the server's SMTP response, and timestamps, with the recipient stored only as a keyed hash — chained into a tamper-evident ledger and verifiable without trusting us.

## What does Kit's security page show?

It cites AWS's and Cloudflare's audits rather than first-party certification. Ours is first-party and open, listing exactly which attestations we hold (none yet) and what we've verified ourselves — a 19-stage adversarial security review, run to zero confirmed findings — at /security . That review was internal and adversarial — a documented find→refute→fix→re-verify loop — not a third-party audit. We say exactly which one we have.

## What are Kit's published fees?

Free to 1,000 subscribers, then Creator from $33 a month rising with list size; commerce at 3.5% plus 30 cents per transaction; paid recommendations take 23.5%. Our pricing is volume-based with unlimited contacts: pricing .
