Deliverability standards have tightened dramatically entering 2027. With Google Workspace, Microsoft 365, and cold outreach sequencers like Instantly and Smartlead enforcing strict 2% bounce ceilings, choosing the right email verification platform determines whether your campaigns land in the Primary Inbox—and whether you pay $59 or $649 per 100,000 leads.
