The short version

  • Each has a real cost: Bluemail its AI features are minimal next to Spark or Canary, so users specifically wanting AI drafting or summaries will find it thin.; Microsoft OneNote notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • They diverge on capability: Bluemail covers Unified inbox, Microsoft OneNote covers Free-form page canvas.
  • Prices and features above were last checked on 1 September 2026.

Microsoft OneNote

  • Handwritten notes on a pen tablet that you still need to find months later by searching for a word you wrote.not Bluemail
  • Lecture or meeting notes where a recording needs to line up with what you were typing at the time.not Bluemail
  • A team already inside Microsoft 365 that needs a shared notebook without buying anything or seeking approval.not Bluemail
  • Collecting mixed material such as screenshots, clippings and sketches on one page, where a document editor would force a linear structure.not Bluemail

Where each one falls short

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

Bluemail

  • Its AI features are minimal next to Spark or Canary, so users specifically wanting AI drafting or summaries will find it thin.
  • The interface exposes a large number of settings and toggles, which makes initial setup slower than more opinionated clients.
  • Business pricing is not published, so an organisation has to go through a sales conversation to learn total cost.
  • Free-tier support is largely community forum and help articles rather than direct responsive support.
  • Some optional cloud features, such as certain sync and backup functions, have historically required a paid add-on despite the base app being free.

Microsoft OneNote

  • Notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • Personal notebooks consume OneDrive quota, which is 5 GB on a free Microsoft account, so a notebook full of scans, images and recordings quietly exhausts the whole account including the space Outlook needs for mail.
  • Sync happens at section level and conflicts are resolved by placing both versions on the page, so simultaneous edits to a large or media-heavy section produce duplicated content that somebody has to merge by hand.
  • Search behaves differently across clients, so what the Windows desktop app finds inside handwriting, images and attachments is not necessarily what the browser or mobile version finds, and the same query gives different answers on different devices.
  • There is no relational structure, no database and no properties, so anything that needs a table of records with fields has to be maintained by hand or moved elsewhere, and OneNote's own tables cannot be queried or filtered.

Answered from the vendors’ own pages

Bluemail: Is Bluemail really free?

Yes, for individual use with unlimited accounts; the paid tier is Blue Mail for Business, aimed at teams.

Microsoft OneNote: Is OneNote really free?

Yes. The application is free with a Microsoft account, with no time limit and no feature gate. What you may end up paying for is the OneDrive storage the notebooks consume.

Bluemail: Does it support Gmail and Outlook together?

Yes, it unifies accounts from any of the major providers plus generic IMAP and SMTP in one inbox.

Microsoft OneNote: Can I keep notebooks off Microsoft's cloud?

The Windows desktop app can keep local notebooks, but they will not sync to other devices and any shared access requires OneDrive or SharePoint.

Bluemail: Does it have AI features like Spark or Canary?

Only basic smart filtering; it does not offer AI drafting or thread summarisation at the level of those competitors.

Microsoft OneNote: How do I get my notes out?

Section by section as a OneNote file, a PDF or a Word document. A OneNote package preserves a whole notebook but only for another copy of OneNote. Third-party converters exist and the page layout usually does not survive them.

Microsoft OneNote: Which version should I install?

Microsoft consolidated onto a single OneNote application on Windows after retiring the Store version, so install the one distributed with Microsoft 365 rather than looking for an alternative.
