Free Email Verifier Tool

Are fake or invalid email addresses causing you to lose money?

Nearly 69% of businesses invest time and money on email marketing.1 It’s easy to see why: The return on investment for email marketing is $36 for every $1 spent.2 That’s a 3,500% return.

That profitability, however, can only be realized if your emails actually get delivered, let alone read. Unfortunately, studies show nearly 16% of all emails go missing or get caught by spam filters.

Why so many emails wind up lost or in spam

Some of these emails may truly be spam — and the email recipient marks it as such.

Other times, hardworking marketers, like yourself, might have purchased an email list that — unknowing to them — contained spam traps (fake emails used to catch spammers).

Many email lists available for purchase are compiled by taking email addresses found on the web. That means a real person never opted in to hear from you.

Internet service providers and blacklist providers seek to prevent spammers from committing fraud. They put fake email addresses in publicly accessible digital spaces (like blogs and forums) to catch and block spammers.

Unfortunately, that means — if you purchased a list with a spam trap in it — your emails could eventually get routed directly to spam or blocked entirely.

Other times, your email list may simply be outdated. People get married and change their last name in their email address. Or they switch jobs and their email address becomes invalid.

They may have even intentionally spelled their email wrong to get the freebie you were offering, but not the emails that come with it.

As a result, the email your team spent valuable time creating never reached an actual inbox — or person.

How ZeroBounce’s free email list verifier can help

Every email you send costs money.

Email service providers typically charge by the number of emails in your list. If your emails go undelivered, unopened or to spam, your ROI diminishes.

ZeroBounce’s free email list verifier allows you to:
  • Clean up your current list in bulk. Already have an email list? Validate up to 100 email addresses every month — no credit card required.
  • Check new email addresses as you go. Verify email addresses as you get them to ensure they’re valid so you reach a real person every time.
