What is Email Checker?

Have you ever wanted to send an email but then receive a message that it is undeliverable? Perhaps the email address is not formatted properly, or maybe it doesn’t even exist! There may be some other reasons as well. 

Email checking ensures that the emails sent are valid, safe, and deliverable. Our tool checks if the emails exist and are correctly formatted.

Email Checker is a free email verification tool. It helps you validate any email address online for free and check if the mailbox really exists.

However, an email checker doesn’t let you know who is behind an email, but it confirms if you should send an email to the relevant address or not. Our email checker tool also lets you know the role associated with an email address. For example, if you enter ‘‘, you get this result:

“Deliverable, but it’s a ‘Role’! Send only if you are familiar with the email owner.”

Isn’t it amazing? And it takes a few seconds to come up with the result. 



Why do you need to check your emails?


Low Emailing Cost

Sending your emails to invalid addresses doesn’t provide you as much return on your investment. Even if you do email marketing in-house, validating your emails will save time and money because increased deliverability reduces work for maintaining mailing lists and databases.

Better Reputation & Decreased Bounce Rate

According to most marketing experts, bounce rates should not exceed 2%. High bounce rates might result in your emails being blocked by internet service providers, and it’s extremely bad for your reputation as well. Validating your email list brings in a better reputation and decreases the bounce rate of your email address. 

Accurate Reporting on Email Campaigns

Invalid emails that don’t deliver or bounce skew your email marketing statistics, making it difficult to evaluate the efficacy of your campaigns. A good email verifier like H-Supertools’ Email Validator cleans your emailing lists. And it helps you gain a clearer picture of your data when making marketing decisions.

Better Leads & Email Marketing ROI

Don’t waste time and money on worthless leads. Ineffective emails will never turn into sales and validating email addresses guarantees that you are communicating with a valid person. Open rates go up when conversion rates increase, resulting in increased sales, increased brand exposure, and improved conversion rates.

General FAQs About Email Checker

Can I check multiple emails at the same time?

Sure. Use our free bulk email verifier instead. 

I checked the email, what kind of email addresses should I avoid sending emails to?

Some of the email addresses you should never use for sending your marketing emails include disposable addresses, invalid addresses, or role addresses. We recommend that you don't use purchased mailing lists. Instead, you should create your own list. Make sure your entire email list is clean.

What is a Disposable Email Address? 

A disposable email address is a temporary email address that isn’t connected to your ID. It’s used as a substitute for forgetting your password or as protection against spam. You can also receive emails at this address and then delete the account afterward, making it spy-proof. There are companies called disposable email providers that provide such emails. 

What does it mean when an email address is marked "Accept all"?

A catch-all, also known as an accept-all email address, is an account that will receive emails sent to various email addresses. It allows the same person to respond to all their accounts without logging in to each one separately.

The Accept-All header indicates that the message should be accepted by every mail server on its route.

What is a Spam trap email?

A spam trap is an actual email address that is used to identify and monitor spam emails in an organization. Spam traps are used by Internet Service Providers (ISPs) and blocklist operators to identify senders who aren't following email best practices. The spam trap email address may have been legitimate at one time, but is now abandoned as an invalid email address.

What are fake addresses?

A fake email address is one that is invalid and thus undeliverable. These are known as invalid email addresses. Such emails enter your list of email addresses when someone types in an incorrect address either knowingly or due to a typing error. Or it might be that this address no longer exists. Emails sent to such bad email addresses always result in hard bounces, harming your sender's reputation. 

What shouldn't I send to Role Address emails?

A role address is used for a post or a role within the organization, not for an individual. Emails sent to a role address are usually shared among a group of recipients. As a result, emails sent to this address have a high chance of being marked as spam by someone in the group.

Will the email checker work with Gmail, Yahoo, and Hotmail accounts?

Yes. The Email Checker will work with all major email providers including Gmail, Yahoo, and Hotmail. It is also compatible with other free webmail services such as AOL Mail, Live Mail, Outlook Express, Windows Live Mail, etc.

Can a "Valid" email address bounce?

Yes, it can. H-Supertools’ email checker tool confirms if the recipient address exists. It doesn’t test the anti-spam policies the receiving mail server employs, as no email is sent. Ensure that your mail server’s DNS data contains valid MX, PTR, DKIM, and SPF records.
