Quick Tool Overview
The Email Risk Score Checker scores an address out of 100 across syntax, disposable domains, role accounts, typos and reserved domains, and itemises every point deducted so the score can be argued with.

About the Email Risk Score Checker
One number for how much you should trust an address, with the arithmetic shown. Every address starts at 100 and loses points for each risk found: a disposable domain costs the most, then a reserved or placeholder domain, then a likely typo, an unattended mailbox, a role account, an unusual top-level domain, a machine-looking local part.
The deductions are itemised rather than summarised, so the score is something you can argue with instead of something you have to accept — which matters when you are using it to decide whether to keep a signup or hold an order for review.
Run it on a list and you get the distribution too: how many addresses fall into each band, and which single risk is costing your list the most points overall.

Frequently asked questions
Every address starts at 100. A disposable domain costs 55 points, a reserved or placeholder domain 60, a likely typo 40, a spam-trap pattern 35, an unattended mailbox 30, a role account 25, an unknown top-level domain 15, and smaller amounts for sub-addressing and machine-looking local parts. Invalid syntax scores zero outright.
It depends on the stakes. For a newsletter signup, 55 and above is usually fine. For a paid order or a free trial, 80 is a more sensible floor. The bands are there to be adjusted, not obeyed.
No. It means the address carries risk signals — most often that it is a role account or a free mailbox on a list where that is unusual. A real person can easily score in the middle band.
No, and it does not pretend to. Existence needs an SMTP check, which a browser cannot perform. The score covers everything decidable from the address itself.
