Methodology

Last reviewed · September 2026

Software changes fast. Our methodology exists so that every claim on this site can be traced to a first-party source and a date — the same process behind our missed-call text-back comparison.

1 · Scope by problem

Every comparison starts from a use case — a missed call, slow follow-up, an agency stack — not from a vendor's feature list. Products are shortlisted because they represent different ways to solve that problem.

2 · Official sources first

Pricing comes from the vendor's own published pages. Features are verified against product documentation and help centers. Where pricing is quote-only, we say so instead of estimating.

3 · Marked, not guessed

Each capability in a comparison matrix carries a verified status: yes, partial (limitation or add-on), no (not designed for this), or unknown (not verifiable from current official documentation).

4 · Testing disclosed

Hands-on testing is identified only where it actually happened. Pages currently state that hands-on testing has not yet been performed — we do not describe first-hand experience we do not have.

5 · Limitations and total cost

Assessments include what a product does poorly, and pricing notes include usage costs and add-ons — not just the advertised entry price.

6 · Dates and corrections

Every page states when it was last verified. Sources carry their own verification dates, so a claim can always be traced to where it came from and when it was checked.
