Achieve better delivery rates and better deliverability with Email Verifications
Increase open rates, avoid the spam folder, and increase revenue by ensuring that email addresses on your list are real and valid before pressing send.
A bad email address is a lost customer
Over 20% of your email database will go bad this year. Invalid email addresses result in unnecessary soft or hard bounces, drive down your engagement metrics for your email campaigns, damage your sender reputation, and cost you money. InboxReady rapidly checks the status of each email address and provides a risk level allowing you to remove high-risk addresses before you mail to them.
With InboxReady, you can protect your sender reputation by reducing your bounce rate, enabling you to reach and engage more people.

Verify both current and new addresses
Check email validity at signup to make sure you’re capturing good data. Clean your list periodically to make sure it stays that way.

List verification feature
Clean your subscriber list of invalid and disposable emails before you send. Our list verification feature is as simple as uploading a .csv.
Not sure whether your list needs a clean? Run a list preview for free. This test version of our Email Verification feature assesses a statistically significant sample of your list so that you can decide whether you need to invest in email list cleaning.

Real-time Email Verification API
Verify email addresses at the point of capture to reduce invalid signups with our real-time Email Verification integration. Whether the email has a syntax error like a misspelled domain name, or the email address doesn’t exist at all – our API will root out all of the bad data, so you’re left with a clean and growing email list.
