Editorial Policy

Last updated

Our guides help people spend real money on software. That’s a responsibility, so here is exactly how we produce them.

Two rules come before everything else. We never claim experience we don’t have: no invented benchmarks, no tests we didn’t run, no vendor marketing numbers presented as our own results. And every recommendation is conditional: each guide says who a tool suits, who should look elsewhere and what its real downsides are.

How we price tools

Prices, plan limits, credit rules and trial terms come from each vendor’s own pricing page, help center and terms, read on the day we check them. Where a guide says so, a figure comes instead from what the vendor’s app showed in our trial account, such as a billing screen or a dialog, with the date we saw it. Deliverability and legal guides rely on the mailbox providers’ and regulators’ own documents. Every guide ends with the sources it used.

  • We quote prices in US dollars as the vendor lists them and say whether a price is billed monthly or yearly.
  • Every price carries the date it was checked, next to the table or in the guide’s byline as “Prices checked”.
  • When a vendor’s own pages disagree with each other, we show both figures and which page says what, rather than picking one.
  • If a number isn’t published, we say so instead of estimating it.
  • We re-check prices on the day we update a page, and fix a price that has changed within seven days of noticing it.

Test accounts

Some guides include a “Hands-on notes” box. It records only what happened in a trial or free account opened for this site, on the date shown, with the plan we were on. Where we haven’t tried something, the guide says it is based on documentation.

  • Who operated the account. Kent F. opens the accounts himself. Some of the clicking inside them is done by an AI assistant working in his account, and every note and screenshot caption says who operated the account.
  • What we don’t do. We don’t email, call or message real prospects from these accounts, we don’t buy anything in them, and we don’t publish anyone’s personal contact data. Screenshots are cropped, and addresses and account or workspace names are hidden.
  • Prices shown in yen. The accounts are opened from Japan, so some apps show prices in Japanese yen. We quote US-dollar prices only: from the vendor’s public pricing page or, where a guide says so, from a billing screen or dialog in our trial account that showed US dollars. We never quote yen amounts; in a screenshot they are cropped out or labelled.

AI assistance and human checks

We research and draft with an AI assistant. A separate AI pass re-opens every cited source and checks each price, limit and rule against the source’s own text. Before a page is published or substantially updated, Kent F. checks its title, its description, every number in its Quick answer and a random sample of its other claims against their sources, and the page shows the date of that check. It is a spot check, not a line-by-line review. Pages published before October 15, 2026 are being checked in turn and will all show a check date by December 3, 2026.

Corrections

If we get something wrong — a price, a limit, a rule or a date — we fix it once we have checked the source, normally within seven days, and change the page’s “Updated” date. Each correction is listed with its date at the end of the page it fixes. We also re-check guides on a schedule and whenever a reader or a vendor tells us something has changed.

To report an error, email [email protected] with the page address and, if you can, a link to the source.

Whether a company pays us never decides whether we cover it or what we recommend. Each guide states the criteria behind its verdict, and a tool we earn nothing from gets the same kind of button when it fits the reader better. We don’t accept payment for reviews, rankings or placement. Applications that are still pending, and how paid links are marked, are in our affiliate disclosure.
