The short version

  • Each has a real cost: 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.; Spark Mail several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • They diverge on capability: MindMeister covers Real-time collaboration, Spark Mail covers Smart Inbox.
  • 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.

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.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

Answered from the vendors’ own pages

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.

Spark Mail: Does Spark host my email?

No. It is a client that connects to Gmail, Outlook, iCloud or any IMAP account; you still need a mail host.

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.

Spark Mail: Does Spark store my email credentials on its servers?

For some features, including cross-device snooze and send-later sync, yes. It is part of how those features stay consistent across devices.

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.

Spark Mail: Is there a one-time purchase option?

No, Spark is subscription only for individuals and teams; the base client is free but AI and unlimited scheduling need Premium.

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.
