--- title: Fastmail canonical: https://saasranked.com/software/fastmail/ category: Email Hosting points: 51 rank: 4 of 9 facts_checked: 2026-10-09 --- # Fastmail Paid mailbox hosting on your own domain, with a 50 GB mailbox, calendar and contacts for each user. 51 points out of 100. #4 of 9 email hosting services. Vendor: Fastmail. Website: https://www.fastmail.com/ - The Standard plan gives each user 50 GB for mail, calendar and contacts, plus 10 GB of files [1]. - Standard costs 25 zł per user a month on a yearly term or 30 zł month to month; the page shows no US dollar price [1]. - IMAP, POP, CalDAV and CardDAV are listed; Basic lacks IMAP, CalDAV, CardDAV and custom domains [1][8]. - Two-step sign-in accepts authenticator apps and WebAuthn security keys [5], and the security page lists passkey sign-in [4][6]. - Fastmail's terms promise no uptime level and mention no service credits [7]. Verdict: Fastmail suits small teams that want a 50 GB mailbox with open protocols on their own domain [1][8]. Standard includes shared calendars, a shared address book and security-key sign-in [1][5]. The catch: the terms contain no uptime commitment, and its business and help pages describe no single sign-on or admin-enforced two-step sign-in [3][15]. Best for: Small teams that want mail, calendar and contacts that work in any standard app. ## Points | Criterion | Line | Value | Points | Note | |---|---|---|---|---| | Price | Cost for a team of 5 | Not published | 0/12 | Price page shows only Polish zloty (Standard 25 zł per user a month, yearly), not US dollars or euros [1]. | | Price | Free plan on your own domain | No | 0/6 | Every plan is paid; the page offers a trial of up to 30 days [1]. | | Price | Monthly billing | Yes | 4/4 | Standard is sold month to month at 30 zł per user, as well as on longer terms [1]. | | Mailbox | Storage per mailbox | 50 | 10/10 | Standard gives 50 GB for mail, calendar and contacts per user, plus 10 GB of files [1]. | | Mailbox | Open mail and calendar protocols | IMAP, POP3, CalDAV, CardDAV | 8/8 | Help lists all four; Basic plans lack IMAP, SMTP, CalDAV and CardDAV, and Standard is above Basic [8]. | | Mailbox | Shared calendar and contacts | Yes | 5/5 | Standard lists shared calendars and a shared company address book [1]. | | Mailbox | More than one domain | Yes | 3/3 | Pricing FAQ: everyone can make addresses on "any domain you have brought into Fastmail"; help says "You can have multiple domains" [1][9]. | | Mailbox | Aliases and catch-all | Yes | 3/3 | Standard lists shared addresses such as support@; help documents catch-all aliases and names no plan limit [1][10]. | | Security | Two-factor sign-in | Yes | 7/7 | Two-step sign-in works with any TOTP authenticator app or WebAuthn keys; the article names no plan limit [5]. | | Security | Passkeys or security keys | Yes | 3/3 | WebAuthn security keys work for two-step sign-in [5]; the security page lists passkey support [4]; passkey help covers it [6]. | | Security | Admins can require 2FA | Not published | 0/3 | Not published on the vendor's administrator help page [15]. | | Security | Single sign-on (SAML) | Not published | 0/5 | Not published on the vendor's business and pricing pages [1][3]. | | Security | SOC 2 Type II or ISO 27001 | Not published | 0/6 | Not published on the vendor's security page or its secure-service help article [4][14]. | | Security | SPF, DKIM and DMARC guides | Not published | 0/4 | Help explains DMARC and points to SPF and DKIM DNS records, but no page read gives steps for all three [11][12]. | | Reliability and support | Written uptime commitment | No | 0/9 | Terms provide the service "as is" and "as available", state no uptime level and mention no credits [7]. | | Reliability and support | Public status page | Yes | 2/2 | Public status page with a notice history link [13]. | | Reliability and support | Live support | Not published | 0/4 | Pricing page promises 24/7 expert support but does not name live chat or phone [1]. | | Reliability and support | Mail migration tool | Yes | 3/3 | Pricing page FAQ: "an import tool that walks you through it" plus a migration guide and free migration support [1]. | | Reliability and support | Official phone apps | Yes | 3/3 | Features page offers a mobile app and links to the App Store and Google Play [2]. | ## Plans | Plan | Price | Per month (USD) | |---|---|---| | Standard | 25 zł per user a month, billed yearly (30 zł month to month) [1] | - | | Professional | 45 zł per user a month, billed yearly (50 zł month to month) [1] | - | Fastmail's price page showed Polish zloty only, tax included, so we record no US dollar price.
