Why it matters
How Confirmed Opt-In fits the work
A documented confirmation gives you a record of consent, which helps with trust, deliverability, and compliance in stricter jurisdictions.
In context
The team's confirmed opt-in flow only counted subscribers who clicked the verification link, so its 12,000 contacts were all verified addresses.
Practical note
Because usage varies, clarify in your own documentation whether "confirmed opt-in" requires a click before adding the contact or simply sends a confirmation.
