Worth knowing
GlockApps

MailMonitor
- Plans start at $1,000 a month, billed annually, and the page says to check eligibility first.
- The vendor says it is not a fit for senders relying only on cold outbound without a warm-up or opt-in plan.
- It says a fit means sending over 10,000 emails a year, so small senders are not the target.
- The Foundation plan covers B2C seed inboxes only; B2B placement tests need Strategic Partnership.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
