Remove unverified newsletter contacts on signup from lists

Your newsletter signups include unverified emails that cause bounces and harm sender reputation. Remove unverified contacts automatically so campaign managers keep lists clean before the next send.

Overview

Bounced and invalid addresses erode deliverability and campaign performance; cleaning signups at the point of entry stops that. This flow validates new subscribers and removes non-verified addresses within minutes, so campaign managers send only to validated lists before the next campaign.
