The short version

  • Only MindMeister has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fastmail it does not provide end-to-end encryption by default, so users specifically wanting zero-knowledge mail should compare it against Proton Mail or Tuta rather than assume parity.; MindMeister the free plan allows three mind maps in total, and a map is a whole document rather than an item, so the cap is reached in a first afternoon of genuine use, making it a demonstration with no clock rather than a usable tier.
  • They diverge on capability: Fastmail covers Custom domain hosting, MindMeister covers Real-time collaboration.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fastmail

  • It does not provide end-to-end encryption by default, so users specifically wanting zero-knowledge mail should compare it against Proton Mail or Tuta rather than assume parity.
  • Moving to Fastmail is a real migration with DNS changes for a custom domain, unlike installing a client such as Spark or Bluemail over an existing account.
  • There is no free tier at all, so a user just wanting to try it commits to a paid trial rather than a permanently free option.
  • Storage limits on the entry Basic plan are modest next to the free allowance Gmail gives, and heavy attachment users will need Standard or above.
  • Being based in Australia means it falls under Australian data access law, which some privacy-focused buyers weigh differently from Swiss or German jurisdictions used by Proton Mail and Tuta.

MindMeister

  • The free plan allows three mind maps in total, and a map is a whole document rather than an item, so the cap is reached in a first afternoon of genuine use, making it a demonstration with no clock rather than a usable tier.
  • Exporting is a paid feature, since the free plan cannot export files at all, Microsoft-format export begins at the Pro tier and compliance export at Business, so retrieving your own work in a portable form costs more than the entry subscription.
  • Pricing is per user and a map's value comes from being seen, so an organisation pays the same rate for people who only read and comment on maps as for the few who actually build them.
  • Attachments are rationed by tier at two per map on the entry plan, so using a map as a project hub rather than a sketch pushes you to a higher tier for a limit that has nothing to do with mapping.
  • Single sign-on and the administrative controls an IT department requires sit on the Business tier and involve a sales conversation, which is where a tool adopted quietly by individuals becomes an organisational purchase at several times the entry price.

Answered from the vendors’ own pages

Fastmail: Is Fastmail a client like Spark, or does it host my email?

It hosts the mailbox itself; there is no separate provider underneath it the way Spark sits over Gmail.

MindMeister: What does the free plan allow?

Three mind maps in total, with unlimited collaborators, templates and presentation mode. It does not include file export, so maps made on the free plan stay in the browser.

Fastmail: Does Fastmail offer end-to-end encryption?

Not by default in the way Proton Mail or Tuta do; its privacy position rests on being subscription-funded rather than ad-funded.

MindMeister: Can I export my maps?

On paid plans. The entry tier adds file export and printing, and Microsoft formats arrive at Pro. What comes out is an image, a PDF or a document, not an editable map another tool can open.

Fastmail: Can I use my own domain?

Yes, from the Standard plan up, with full alias and masked email support.

MindMeister: Does it work offline?

Treat it as needing a connection. If you are running a workshop somewhere with unreliable network, export or print what you need beforehand rather than relying on the browser.

MindMeister: How does it relate to MeisterTask?

Same vendor, separate products and separate licences. Map branches can be sent into MeisterTask as tasks, which is the main reason to prefer it over a general whiteboard tool.
