NextGen Email Validation

SafeToSend®: Next Generation Email Validation

Every marketer knows the frustration of campaigns underperforming. Engagement drops. Deliverability suffers. Revenue potential gets lost in a sea of bad data. What’s holding you back?

It’s not just invalid emails. It’s outdated validation methods.

Traditional email validation tells you if an address exists — but that’s not enough anymore. SafeToSend goes further, using real-time activity and engagement signals to determine if an address is not just valid, but valuable.

Every email list has hidden threats: toxic but deliverable emails, spam traps, and inactive contacts that silently sabotage your deliverability. SafeToSend identifies them before they impact your campaigns, ensuring every email you send reaches real, engaged users.

SafeToSend goes beyond bounce detection to provide real-time, multi-layered intelligence that doesn’t just validate emails; it analyzes, scores, and protects your database to ensure every email is an asset, not a liability.

Need for a Better Solution

The Limitations of Conventional Email Validation

For years, email validation has been stuck in the past—merely confirming if an address exists without considering whether it’s actually valuable. While this reduces bounce rates, it overlooks critical factors that influence campaign success barely scratching the surface of what’s possible:

Hidden Deliverability Killers: Spam traps, bots, and toxic addresses erode sender reputation, leading to inbox placement failures.
Engagement Black Holes: Outdated emails and abandoned inboxes waste ad spend, lower open rates, and inflate acquisition costs.
Revenue Leakage: A single bad email can derail triggered workflows, misattribute conversions, and corrupt personalization efforts.

Beyond the Binary Valid or Invalid

We Don’t Just Verify Emails — We Analyze Behavior

Most validation tools rely on outdated SMTP pings and static databases. SafeToSend analyzes real-time email activity across billions of signals every month to provide deeper insights.

This means you can segment audiences more effectively, tailor messaging, and focus efforts on contacts most likely to convert:

Knowing if an email is used regularly, not just whether it can receive mail.
Identifying whether an email is associated with toxic behavior.
Detecting spam traps before they damage your sender reputation.

Inbox Placement & More Conversions

True success isn’t just about getting emails sent — it’s about getting them opened. SafeToSend protects your sender reputation, ensuring emails land where they should: in front of engaged, high-value customers.

Lower Acquisition Costs & Higher ROI

Wasted spend on fake or low-quality signups is a massive hidden cost. By eliminating risky and inactive addresses upfront, SafeToSend helps maximize the value of every dollar spent. More real people, fewer dead ends.

Stronger Personalization & Attribution

A clean, accurate email list means better segmentation, more precise targeting, and more relevant messaging. It also means accurate attribution — so you can trust your analytics and optimize spend based on real performance.

Improved Fill and Accuracy

Minimize the Unknown with Machine Learning-Driven Decisioning

Traditional validation methods often yield a significant percentage of “unknown” results, leaving marketers in the dark about a substantial portion of their contact lists. SafeToSend employs advanced machine learning models, analyzing approximately 100 billion monthly email activity signals to reduce these unknowns dramatically.

Clients have experienced an average reduction in unknown rates by 6%, with some seeing decreases up to 29%.

This enhancement translates to tens of thousands of additional verified emails, expanding your addressable audience and improving campaign ROI.

Spellcheck for Email Addresses

Rescue and Retain Potential Leads with Intelligent Correction

Human error in data entry can lead to lost opportunities. A simple typo can mean the difference between gaining a new customer and losing them forever. SafeToSend acts as an intelligent spell-check for email addresses. This capability allows you to recover and engage with contacts who might otherwise have been unreachable, correcting:

Misspelled Domains: Correcting “gnail.com” to “gmail.com.”
Extra or Missing Characters: Identifying and amending errors like “user@@domain.com.”
Invalid domains (e.g., yaho.cmo ➔ yahoo.com)

Our customers consistently report higher deliverability rates, improved engagement metrics, and reduced marketing costs after implementing.
