The short version
- 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.; RowShare it is a table rather than a spreadsheet, so the formula and analysis capability people expect from Excel is not there, and anything requiring modelling or charting has to be exported and finished elsewhere.
- They diverge on capability: Fastmail covers Custom domain hosting, RowShare covers Row-level permissions.

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.
RowShare
- It is a table rather than a spreadsheet, so the formula and analysis capability people expect from Excel is not there, and anything requiring modelling or charting has to be exported and finished elsewhere.
- It is a small independent product, so putting a recurring business process on it means a single vendor decision can end that process, and unlike the larger alternatives there is no ecosystem or partner network to fall back on.
- Integration is largely through Zapier rather than deep native connectors, which adds an intermediary service, another subscription and another place for a data flow to fail silently.
- The niche it occupies is increasingly covered by list tools included in Microsoft 365, so the purchase has to be justified against something the organisation may already be paying for and already administers.
- Licensing in this category is per user, so if contributors need accounts rather than form links, an occasional contributor costs the same per head as a daily one, and it is worth confirming which model applies before planning a rollout.

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.
RowShare: How is this different from a shared spreadsheet?
Sharing is per row rather than per file. Everyone works in one table, and each person sees only their own rows, which removes the consolidation step rather than speeding it up.
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.
RowShare: Can I get my data out?
Tables export to Excel and CSV, so the data itself moves. The permission structure, forms and reminders that made the process work do not, so an exit means rebuilding the workflow.
Fastmail: Can I use my own domain?
Yes, from the Standard plan up, with full alias and masked email support.
RowShare: Is it a database?
No. It is a permissioned table with typed columns, not a relational store you can query, so it collects structured data rather than modelling it.
RowShare: Who is behind it?
A French vendor with named enterprise customers. It is a small company, so weigh continuity carefully before making it the home of a process you expect to run for years.
