Buttondown is the most likable company in this genre: indie, plainspoken, and its /alternatives hub is the honesty benchmark comparison pages should be graded against — including this one. The differences are structural, not moral. Buttondown delivers through Mailgun and Postmark, runs on Heroku, prices per subscriber with tagging, paid subscriptions, analytics, and RSS-to-email each a $9-a-month add-on, and assumes at most about one email a day. Email Fast owns its delivery and bundles all four.
The comparison
| Buttondown | Email Fast | |
|---|---|---|
| Delivery | Via Mailgun and Postmark, per their own subprocessor list | Email Fast runs its own mail transfer agent, warmup engine, reputation breaker, and per-tenant fair queue — the pipes are ours, not resold |
| Hosting | Heroku | Dedicated infrastructure we operate (security) |
| Tracking | Off by default since 2021 — credit where due | open tracking that refuses to lie: privacy-proxy prefetch “opens” are detected and not counted as human reads |
| Pricing model | Per-subscriber; tagging, paid subscriptions, analytics, and RSS-to-email are $9/month add-ons; assumes at most one email a day | contacts and subscribers are never billed — we price sending, not the size of your audience — and those four features are bundled (pricing) |
| Security certifications | No certification page published | None held here either — the difference is an open security page saying exactly that |
Privacy, theirs and ours
Buttondown turned email tracking off by default in 2021 — a real commitment, made early, and we credit it. Our approach makes privacy checkable rather than promised: a vendor-access transparency log: a tamper-evident chain that records operator access, so “we never looked” is checkable, not promised. And where opens are tracked at all, the counting is honest — open tracking that refuses to lie: privacy-proxy prefetch “opens” are detected and not counted as human reads.
Where Buttondown is the right choice
- You want indie and personal, from people who mean it. Default-off tracking and an honest /alternatives hub are the receipts.
- Your cadence fits their design center. A modest list, at most about one email a day.
- Values alignment outranks infrastructure ownership for you — a defensible position we simply weigh differently.
Switching
Export your list and bring it over — contacts and subscribers are never billed — we price sending, not the size of your audience. Tagging, analytics, RSS-to-email, and paid subscriptions are bundled, with the honest note that reader billing opens with general availability. Start with a sandbox key: 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.

Questions, answered plainly
Is Buttondown trustworthy?
Every signal we verified says yes: email tracking off by default since 2021, a subprocessor list that names names, an /alternatives hub that treats competitors honestly. This page exists because of structural differences — delivery, pricing, bundling — not doubts.
Who delivers Buttondown's email?
Mailgun and Postmark, per their own subprocessor list; they host on Heroku. The wider context: every newsletter platform we surveyed rents its delivery: beehiiv's status page lists SendGrid components; Buttondown's subprocessor list names Mailgun and Postmark; Substack sends through Mailgun (verified on their own public pages, July 2026).
What do the add-ons cost?
At Buttondown, tagging, paid subscriptions, analytics, and RSS-to-email are each a $9-a-month add-on, on top of per-subscriber pricing that assumes at most about one email a day. Here all four are bundled on every plan (reader billing for paid subscriptions opens with general availability), and contacts and subscribers are never billed — we price sending, not the size of your audience.
What does Email Fast offer beyond default-off tracking?
Verifiability — a vendor-access transparency log: a tamper-evident chain that records operator access, so “we never looked” is checkable, not promised. And for organizations that want custody, not policy: organizations can bring their own encryption keys — enroll, rotate, suspend, or revoke — and revocation fails closed: new sends are rejected and stored secrets become unreadable, to us included.
