Bulk email validator

Our bulk email service is an essential email checker that gives you an easy way to immediately clean your list of invalid email addresses that contain syntax errors, typos, and other factors like list addresses and full inboxes. Better for you, and easier on your email service provider (ESP).

Invalid email addresses can wreak havoc

Unfortunately, every time someone on your email list changes jobs or email service providers, their email address changes too. This means that on a monthly basis, roughly 2% of your contact list may be made up of invalid email addresses. Without proper list management, this can translate into more than 25% of a company’s mailing list being rendered invalid every year. What’s more, email address typos or email domain syntax errors on sign-up forms can result in invalid email addresses, translating into missed opportunities for your sales team, a higher bounce rate, and a rocky relationship with your ESP.

Keep email lists current with validation and email validation

Since a valid email address is essential for bulk email marketing, regular bulk email list verification is essential for sending emails. Usually, the easiest way to build a list and verify emails at the same time is through a web form. When an email validation tool is not in place, users may enter invalid email addresses, spam traps, or disposable mailboxes. If you send a bulk email without an email verification process your messages end up bouncing, and your sender score and email deliverability both end up suffering for it.

There is nothing more frustrating than sending out bulk emails for your email marketing campaigns only to have those messages bounce back, be rejected by the mail server, or get marked as undeliverable due to bad email addresses. That’s why an integrated email verification process is so important for email campaigns. Using an email verification tool allows for real-time email verification through your web application.

While you can verify email addresses manually, this gets pretty tedious for lists with hundreds or thousands of b2b email addresses. In these cases, using a bulk email verifier tool is a necessity for clean lists. An email validation tool like our bulk validations provides a bulk email verification service quickly and all in one go, allowing for a catch-all solution for your email lists. Simply upload your CSV file and we take care of the rest.
