How temporary inbox services work and how to detect them at signup without hurting real users.
The problem
Temporary inbox services let anyone create an address that disappears within minutes. They're used to farm free trials and skew signup metrics.
How detection works
Verifiers maintain constantly updated lists of disposable domains and combine them with MX patterns. Bytecheck returns checks.disposable: true when an address matches.
What to do
Block or require extra verification for disposable addresses on free trials; allow them where anonymity is expected, like newsletters.
