What is an email verifier and why should you care?

Email marketing is an indispensable part of nurturing your relationship with your customers. Let’s see how an email verifier facilitates email marketing and eventually boosts sales and revenue.

An email verifier is a system that removes invalid and fake email addresses from your email list. By doing so, it boosts your sender score and your email deliverability. Here is a detailed description of what it does and how it can help your business.

Helps discard dormant email addresses

An email verifier skims through your contact list and marks those addresses that are defunct or no longer valid. The causes can vary, such as a person changing their email address or switching their job or position, or the domain/provider closing down. This helps you do away with addresses that are inoperative. At the same time, you can focus on leads you could re-engage with.

Helps correct human typo errors

Typos in email addresses can keep you from reaching potential customers, adversely impacting your business’s sales and revenue. An email verifier comes to your rescue by identifying these misspelled addresses.

Helps you steer clear of spam traps

Your IP address could be marked as a spam or added to a blacklist if you accidentally deliver emails to a spamtrap. An email verifier helps you identify and strike off such contacts from your list.

Enhances sender reputation

If too many of your emails bounce, your sender score deteriorates and wrecks your sender reputation. An email verifier helps you discard invalid email leads, making sure your campaigns end up in customers’ inboxes. Your sender score and reputation improve.

Saves resources

Sending out newsletters to invalid email addresses is a loss of resources and budget. An email verifier helps you get rid of inactive addresses. It enables you to focus on the valid ones, ensuring higher response rates to ads and campaigns.

Facilitates better campaigning

Eliminating inoperative email addresses from your contact list gives you a more pragmatic view of your open rates (percentage of opened mails out of the delivered mails), clicks and conversions.

Averts hard bounces

Hard bounces increase your bounce rate and impact your open rate adversely. This dooms your email id to be blacklisted and marked as a junk mail by customers. An email verifier helps eradicate this problem by marking those addresses on your list that are expected to bounce.

Helps achieve steady leads

Inactive, defunct, and bad email addresses in your contact list might wrongly reflect customers’ demographic data. They might even result in you missing out on credible leads. An email verifier assists you in focusing on only convertible steady leads by eliminating bad email addresses altogether.

Furnishes better data insights

Email verification helps you focus on potential leads and their critical demographic data. It assists you in drawing better conclusions and make improved marketing decisions with accurate insights into the customer’s behaviour.

Enhances cross-channel marketing

An email verifier enables you to hone in on loyal subscribers. This results in better brand promotion across multiple channels, and not just e-mail. It helps you gain coherent insight into your customer’s statistics that could help you campaign across all channels.

There are various email verifiers you can use to determine invalid email addresses on your contact list. The different types of email addresses that need to be stricken off of your contact list are as follows:

Defunct email addresses

These include abandoned email addresses that no longer exist.

Misspelled email addresses

These are a result of typos in the e-mail IDs owing to human errors. For example: [email protected] or xyz@domaincom

Role account addresses

There are some email addresses related to a certain department or division within an organisation. They are meant to receive emails related to the activities and responsibilities of that division. For example: [email protected] or [email protected] are not for marketing emails.

Spam traps

Used as a honeypot to lure spams, such email addresses can creep into your contact list accidentally. Using a double opt-in method to get your customers acknowledge their subscription, can help avert these accidents.


If you are a business owner and own a website, make sure you do not display your email address conspicuously on your home page. Instead, hide it behind a phrase such as “Contact Us”, using a hyperlink. Spam robots tend to scan websites to extract visible email addresses and make way into their inboxes.

Sending emails to invalid addresses brings down your sender score. It may result in your emails getting blacklisted and marked as spam. This could damage your sender reputation, adversely impacting your sales and revenues. Hence, using an email verifier is a recommended measure for a reputable and profitable business.
