Switching from Substack: easy move, hard decision

The mechanics of leaving Substack take an hour. The decision deserves longer, because what you'd leave is a discovery network that actually grows lists — and what you'd gain is infrastructure and economics you control.

The decision, before the mechanics

Substack's discovery network — recommendations, Notes, the app — grows lists in a way infrastructure never will, and it takes its published share of your paid revenue for the privilege; the dated terms below carry the figure. Leaving trades network growth for owned economics. That trade is right for some writers and wrong for others, and this page's job is to make the trade visible, not to sell it.

The mechanics, in order

1. Export your subscriber CSV from Substack — free and paid lists both, so you have your own complete copy either way.
2. Import free subscribers here. The CSV import screens each address and reports anything it skipped. Unsubscribes come over first, as suppressions.
3. Leave paid where it is, for now. Reader billing here opens at general availability — until then your paid relationship stays on Substack, and moving it later is a re-subscribe ask, not a file transfer. We say this above the fold because finding it out mid-move is the failure mode.
4. Stand up the publication: public archive, RSS, and hosted signup forms with confirmed opt-in on every plan — hosted signup forms with double opt-in through our own delivery path, so every subscriber carries verifiable proof of consent.
5. Send the first issue dry to prove the pipeline: sandbox keys (ef_sandbox_…) that run the real pipeline dry: real validation, real rendering, real events, a hosted capture inbox — and no email leaves.

The free-list move is an hour. The archive is yours to move by hand or leave standing. Growth becomes your job again — that's the honest cost of the trade.

What Substack publishes

Substack publishes no per-send or per-contact price because there isn't one: publishing is free at any list size. When paid subscriptions are switched on, Substack keeps 10% of each transaction, plus payment processing (Stripe: 2.9% + $0.30 per transaction + 0.7% recurring billing fee).

Detail: 'Publishing is free on Substack - no matter how many subscribers you have.' When paid subscriptions are enabled: Substack takes 10% of each transaction, plus Stripe fees (2.9% + $0.30 per transaction, plus 0.7% recurring-billing fee as of July 2024). No per-contact or per-send charges at any list size. Secondary source: https://substack.com/going-paid.

The comparison axis is unusual: at zero reader revenue Substack costs nothing, and at meaningful revenue the share is the price. Email Fast prices sending volume instead — price your cadence to see both models against your numbers.

Where Email Fast stands

Our stake, declared: we make Email Fast, and these are the launch prices already published on our pricing page — during early access they may be refined before general availability, and self-serve checkout opens at GA. Contacts and subscribers are never billed, at any list size.

Where Substack wins

From our own pricing survey, their side stated plainly — Zero cost until you earn, payments/infrastructure fully handled, and a real discovery network (recommendations, Notes, app) that actively grows subscriber bases.

Honest additions: zero operational surface is a genuine product — no DNS, no domain verification, no settings to get wrong. And if writing is your whole job, Substack keeps it that way better than any infrastructure product can. The full comparison: Substack vs Email Fast.
