Is Purelymail actually $10 a year, or is that a teaser price?

Purelymail's own pricing page states $10/year flat under its "Simple pricing" plan with no per-user, per-domain, or per-GB charge, and no advertised hard limit — usage well beyond that is expected to move to their separate, metered "advanced pricing." Confirm current terms on purelymail.com/pricing before committing, since usage-based pricing changes are the part most likely to move.

Does Migadu support catch-all addresses?

Yes, but Migadu's own site frames it as supported-but-discouraged rather than a headline feature — their marketing copy explicitly says catch-alls are not recommended, likely for spam and deliverability reasons.

Which one has calendar and contact sync?

Purelymail documents CalDAV and CardDAV support directly on its features page, along with basic file storage. We could not find equivalent calendar/contacts documentation on Migadu's public marketing pages as of the checked-on date.

Is either of these good for a small team, not just one person?

Both support multiple mailboxes per account with no per-mailbox fee, which is unusual — most competitors bill per user. Migadu's tiers are priced by storage, not seats, and Purelymail's flat plan explicitly allows multiple users at no extra charge.

Third-party comparison · not affiliated with either

Migadu vs. Purelymail: two very different bets on cheap, serious email.

Migadu starts at $19/yr for 5 GB and scales to $990/yr for 500 GB across four fixed tiers; Purelymail is a flat $10/yr with no hard limits on users, domains, or storage under fair use, plus a separate metered plan for heavy senders. Purelymail includes DKIM, CalDAV/CardDAV, and SpamAssassin explicitly on its features page; Migadu's public pages document unlimited domains/mailboxes and catch-all support but not calendar sync. Both are independent, non-Big-Tech custom-domain mail hosts with no per-mailbox fee.

Both are independent, developer-favored custom-domain email hosts with no ads, no per-mailbox fees, and unlimited domains on paper. That's where the similarity ends: Migadu tiers storage and price ($19–$990/yr), while Purelymail sells one flat $10/yr plan with no hard limits at all, backed by a separate pay-per-resource tier for heavy usage.

This page compares them on their own public pricing and docs — not on how either compares to Folio. If you're weighing a multi-domain operator inbox instead, the honest Folio note is near the bottom, not the headline.

I · The verdict

In one sentence.

Purelymail is cheaper and more standards-complete (DKIM, CalDAV/CardDAV, SpamAssassin, routing rules) at $10/yr with no per-user or per-domain fee. Migadu is more predictable at scale — a fixed year-ahead price per storage tier, and a policy that discourages (rather than technically blocks) catch-all abuse. Purelymail's growth path is usage-based and less predictable; Migadu's is a plan upgrade.

III · How to choose

Pick the right one.

Choose Migadu if

You want a fixed, predictable year-ahead price and don't mind paying more for it as you grow.

You'd rather budget a known annual number than track resource usage.
You want a vendor with an established public track record rather than a newer entrant.
You're comfortable skipping catch-all addresses — Migadu's own docs steer you away from them.

Choose Purelymail if

You want the cheapest serious option and you're comfortable with a usage-based safety valve.

$10/yr beats every Migadu tier on price, with no per-user or per-domain surcharge.
You specifically need CalDAV/CardDAV sync or a documented catch-all workflow.
You're a lighter sender — heavy senders should read Purelymail's advanced/resource pricing page before committing.

IV · A deeper look

Pricing philosophy: fixed tiers vs. flat-plus-metered

Migadu's four tiers (Micro $19/yr, Mini $90/yr, Standard $290/yr, Maxi $990/yr) trade storage for price in fixed steps, and every tier includes unlimited domains and mailboxes — the constraint is disk, not seats. Purelymail inverts this: one $10/yr “Simple” plan with, in their own words, “no hard limits. Not on users, custom domains, storage, or anything else,” soft-capped by fair use, with a separate pay-per-resource tier if you exceed it.

The practical difference: Migadu's ceiling is a plan you choose in advance. Purelymail's ceiling is usage you find out about after the fact via the advanced pricing calculator. Budget-conscious solo operators tend to prefer Purelymail's headline price; teams that want to forecast a fixed line-item tend to prefer Migadu's tiers.

V · A deeper look

What each includes that the other doesn't say it does

Purelymail's own features page is more itemized: DKIM is named directly as a deliverability control, CalDAV/CardDAV sync ships for calendars and contacts, and SpamAssassin is named as the spam engine. Migadu's public marketing pages describe the protocol surface (SMTP/IMAP4/POP3/webmail) and aliasing/catch-all support, but we could not find equivalent public detail on DKIM key management or calendar sync on migadu.com — that doesn't mean it's absent, only that it isn't documented where a buyer would look first.

If calendar sync or DKIM controls are a hard requirement, verify directly against each vendor's current docs before switching — this page reflects what was publicly documented as of the checked-on date below, not private support-ticket answers.

VI · Cheapest to most expensive

The numbers, in US dollars.

Plan	Migadu	Purelymail
Entry tier	Micro — $19/yr (annual billing only), 5 GB	Simple — $10/yr, no hard limit
Mid tier	Mini — $90/yr annual, or $9/mo billed monthly, 30 GB	— (same flat plan)
Higher tier	Standard — $290/yr annual, or $29/mo billed monthly, 100 GB	Advanced/resource pricing for heavy usage
Top tier	Maxi — $990/yr annual, or $99/mo billed monthly, 500 GB	— (metered, not a fixed tier)

VII · A note from the people who make Folio

Editorial aside — not a sales pitch

Neither Migadu nor Purelymail is about one inbox for many identities — that's a different problem.

Both Migadu and Purelymail are excellent, no-nonsense custom-domain mail hosts built for people who want raw SMTP/IMAP control at a low price. Folio solves a narrower, different problem: one operator reading and replying across many business domains without juggling accounts.

Where Folio fits

You run several distinct brands or LLCs and want one reading view instead of switching accounts or webmail tabs per domain.
You want reply-From picked automatically based on which domain a message arrived on, without manually selecting a send-as identity.
You want per-domain DKIM generated for you at bind time instead of managing DNS records by hand for each domain.

Where it doesn't — pick Migadu or Purelymail instead

You're happy managing DNS yourself and just want the cheapest possible raw mailbox — Purelymail's $10/yr is hard to beat on price alone.
You need a fixed, long-term predictable line-item and don't need a unified reading view — Migadu's tiers do that well.
You need calendar/contacts sync as a first-class feature today — Purelymail ships CalDAV/CardDAV now.
