A.I. Email Scoring and Catch-All Validation

ZeroBounce Email Scoring supplements your email verification results with an email scoring system that rates the value of an email address.
Provides in-depth scoring on your HubSpot emails to gauge subscriber engagement and activity levels.
Pinpoint and remove catch-all email addresses that are abandoned or have low activity.
Pinpoints email addresses with a high conversion rate potential.
Benefits:
Remove potentially harmful catch-all email addresses that can't be verified with an email validation tool to protect your bounce rate and email sender score.
Never waste a valuable lead
Get a higher ROI from your email campaigns by identifying real, engaged inboxes.

Activity Data
ZeroBounce Activity Data is the perfect supplement to the email verification and validation integration. This add-on service measures subscriber activity in the following ways:
Identify if and where subscribers are active - on the web or in the inbox
Tracks reader activities like opens, clicks, forwards, and unsubscribes
Measures activity levels in the last 30, 60, 90, 180, 365, and 365+ days
Engage active HubSpot leads, and avoid dormant subscribers
Activity Data is also included with the ZeroBounce HubSpot email verification service.
Real-time Email Verification and Validation
ZeroBounce integrates seamlessly with HubSpot Forms, which allows us to spot fake email signups automatically.
Additionally, you can turn on Contact Monitoring at any time, and ZeroBounce automatically verifies any new email address added to your HubSpot lists.
Schedule Email Verification and Scoring
With ZeroBounce, email verification and validation never has to be a manual task. Here's how:
Select any HubSpot email list from your account.
Schedule how often you want to perform email verification and validation. (e.g., Clean this list once every two months.)
ZeroBounce provides email verification for that list according to your set schedule.

Features

Detect invalid and obsolete emails
ZeroBounce detects and segments invalid and inactive email addresses to help you prevent bounces and protect your sender reputation. Before you hit Send, be more confident about the contacts in your CRM.

Identify spam traps
Spam traps aren’t real email addresses but contacts created by anti-spam organizations to block spam senders. These types of emails cause huge email deliverability issues, so pruning them out of your list is key.

Segment abuse emails
Spam complaints tarnish your sender reputation and can cause your campaigns and cold emails to land in spam. Identify subscribers with a history of spam reports and decide whether you want to continue to send emails to them.

Weed out disposable emails
Has someone signed up for your email list using a disposable email address? ZeroBounce spots these types of emails and allows you to remove them. Keeping them in your CRM causes your campaigns to bounce, as disposable emails self-destruct within days or even minutes.

Isolate role-based emails
Role-based emails (like office@ or admin@) have a high bounce risk, which can quickly taint your sender reputation and cause your future emails to go to spam. ZeroBounce segments these emails so you can decide whether to keep them or not.
