What are Email Verification Tools?

Email verification tools ensure that emails are deliverable, to reduce bounces, and improve email marketing and outreach campaign performance. Additionally, email verification tools help clean bots and inactive users from your mailing list to ensure business emails hit real, active recipients and avoid the spam box.

Businesses use email verification tools to maximize the number of their emails that get read, as well as to save money on mass emails. Since mass emailing services often charge by the number of recipients on the mailing list, pruning inactive accounts from a mailing list and avoiding the spam box helps businesses get the most out of their money when it comes to mass emails.

Email Verification FAQs

What happens if I need to spend more emails than my monthly allotment?

Some email verification tools are priced on a pay-as-you-go basis with payment at the end of the month depending on how many emails were sent. Others are a monthly subscription that allows for a certain amount of emails each month. These types of subscriptions usually allow users to pay overages to send additional emails, but doing so often can be cost prohibitive.

How do email verification tools reduce email bounce rate?

Email verification tools reduce bounce rate of emails by detecting spam email accounts and removing inactive email addresses from an organization’s contact list. By keeping only legitimate email accounts in an organization’s contact list, they can ensure that their emails reach active readers and avoid the spam box.

Are there free or open source email verification tools?

There are some free to use email verification tools, though they tend to be more limited compared to premium options. Most free email verification tools simply validate whether email addresses are legitimate or not. Businesses looking for email automation, or who want to quickly validate a large number of email addresses may prefer more fully featured options.
