Email issues we help fix
ZeroBounce’s email verification service helps you clean up your email list by removing:
Email typos- Nonexistent email accounts
- Email accounts likely to mark your messages as “spam”
- Spam traps
- Other risky email addresses
Why you need to verify your emails
Your sender reputation is at stake.
When you email incorrect, fake or spammy email addresses it drives up your marketing costs and drives down your ROI.
Over time, it can also impact your sender reputation, which is like a credit score for your email address. The more “bad” addresses you email, the worse your emails perform and the lower your score.
This means your email list not only impacts the effectiveness of your email campaigns today, but your future deliverability, too.
How ZeroBounce helps you reach the inbox
Validate
Validate email lists
Prevent email bounces and spam complaints before they occur. Use ZeroBounce’s bulk email verifier to remove low-quality contacts from your list, including invalid, spammy and abuse email addresses.
This can help reduce your bounce rate, increase your open rate and prevent you from landing in spam.
After you’ve cleaned your list, keep it that way. Connect ZeroBounce’s email validation API to your signup and registration forms. That way, each time someone enters a new email, it gets checked in real time. Only real, valid contacts will end up on your list.

Score
Score email contacts
Spend more time reaching people who might want to hear from you. Use ZeroBounce Score™ (our email scoring system) to discover the true value of your email contacts.
Think of it this way: Email validation helps you determine if an email address works. Email scoring takes it a step further: it scores people based on their reachability and interactions.
ZeroBounce Score offers a quality score for each contact in your list. The higher the score, the more likely that person will engage with your emails.
Now, you can further validate catch-all emails — and keep, nurture and convert high-activity accounts.
