How is the score on this chart worked out?

It is the average of three of the five grades ToolGPA gives every tool: features, ease of use, and platforms and integrations, with an A worth 4 and an F worth 0. The other two grades, value for money and the free plan, are about price, so they are left out and price gets an axis of its own. 8 of the 16 email verification and deliverability tools are on the chart; 8 are left off because they are sold for a single payment or publish no price that can be put as dollars a month.

How this chart is made

  • The score is the average of three of a tool’s five grades: features, ease of use, and platforms and integrations. An A is 4 points and an F none. Value for money and the free plan are left out because they are about price, and price has an axis of its own.
  • The price is what paid plans start at, in dollars a month, on the cheapest way of paying the listing names. A yearly price is divided by twelve, and a price in another currency is converted. A price for each person is shown for one person.
  • A tool with no paid plan sits in the band marked Free. A tool with a free plan beside paid ones is placed at its paid price and drawn as a filled dot.
  • The grades are ToolGPA’s own judgement from each vendor’s pages and from public reviews, not from testing, and no vendor can pay for one. How we grade
