Bulk email verification removes invalid and inactive bulk email verification from your contact list, increasing your deliverability rates and boosting the effectiveness of your marketing campaigns. Email servers reject messages that are sent to undeliverable or nonexistent email addresses because they could be considered spam, harming your sender reputation and potentially leading to your email server being blacklisted. Invalid or outdated email addresses can also result in bounce-backs and spam complaints, further lowering your deliverability rates and potentially reducing the effectiveness of your campaigns.

Regularly cleaning and purging your list is a necessity. It is estimated that up to 45% of emails are no longer valid, due to people changing email addresses, leaving companies, or moving to different locations, for example. In addition to removing old and obsolete email addresses, an effective bulk email checker can replace those addresses with new, valid ones, stimulating your marketing campaigns.

It will then provide you with a detailed report of the results, showing each email’s status as either ‘Valid’, ‘Risky’ or ‘Invalid’. Invalid and Risky email addresses will be added to a blacklist, meaning that they will never again be included in your clean lists. It integrates seamlessly with popular ESPs such as MailChimp, Mailjet, Mandrill, Mailgun and Postmark to protect you from sending spam to their recipients and keeps a record of any bounces, unsubscribers or spam complaints so that they don’t damage your sender reputation.
