Each country page covers what your list meets in that market: the marketing-email law as its regulator words it, with the date we read it, and the mailbox providers common there.
The verification is the same everywhere. ZapBounce runs its own SMTP check, closes before any message is sent, and never bills an unknown result. What changes by country is who you may email and which domains fill your file, so each page starts from the regulator's own guidance.
