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 the 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 a missed opportunity for your sales team.

Keep Email Lists Current with Validation and Email Verification

Since a valid email address is essential for bulk email marketing, regular email list verification is essential. 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 or disposable mailboxes. If you send a bulk email without an email verification process, messages may miss their target.

There is nothing more frustrating than sending out a bulk email mailing only to have several of those messages bounce back, be rejected by the mail server, or get marked as undeliverable. That’s why an integrated email verification process is so important. Using email verification software allows for real-time 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. An email validation tool can provide bulk email verification automatically, saving you time and resources.
