Add email verification result to new subscribers list

Your subscriber list has unverifiable emails that cause bounces and skew deliverability. Add verification to contacts and record invalid addresses so campaign teams can act same day.

Overview

Dirty subscriber data inflates bounce rates and hides deliverability issues from your analytics. This flow verifies each new subscriber, writes status back to contact records, and builds a same-day bad-address log so campaign managers and data analysts can remove or suppress bad addresses before the next send.
