If you’re an email marketer, you need to verify that the content that you’re
sending to followers actually reaches their inboxes. That’s why the
NeverBounce email checker is a valuable tool — it quickly analyzes email
lists of any size, identifying which addresses are valid and which are not.

This helps you avoid sending emails to addresses that have “gone bad.” As a result, you’ll keep your
 bounce rate right where it should be, assuring that you never find out the answer to “What happens if my
 email gets blacklisted?”. Understanding how to check if an email address is valid and the importance of
 email verification is essential for all email marketers before sending messages.

How to Use Our Free Email Verifier

You need to be confident that the email addresses on your subscriber list are valid before sending emails to your followers. With our tool, you can verify an email address without sending an email. This helps you guard against a high bounce rate before even launching your campaign.

Our one-off email checker isn’t our only free tool to protect you from bad email data. While you test email addresses, you can also use the free list analysis tool as a bounce checker. After analyzing your subscriber list, it will estimate how many emails might bounce if you were to send content to everyone on your list. The free list analysis is available in the NeverBounce user dashboard. Register here to analyze your list.

NeverBounce determines the validity of an email using hybrid verification, combining accept all detection with real-time verification, resulting in the most accurate, up-to-date results available.
Email marketing is effective because it lets you stay in contact with your brand’s followers over a long period of time. This is key to building positive business relationships. That said, if you consistently send emails to invalid addresses, your content may not always reach your subscribers’ inboxes. Using both of these tools as an email and bounce checker to verify an email address without ever sending an email will make sure that you land in the inbox.

Can I check if an email address is valid without actually sending an email?

Absolutely. After all, your goal is to avoid sending emails to invalid addresses. You shouldn’t have to send any messages just to check your list. Our email checker upholds this and lets you verify an email address without sending a single email.

How many emails can I verify at once?

The NeverBounce email verification tool is capable of processing as many as 10,000 emails in as little as 3-10 minutes.

What happens if my email gets blacklisted?

There are several potential consequences to your email being blacklisted. In many cases, your emails will be directed to spam folders, limiting the odds of your followers actually seeing them. However, getting blacklisted can also prevent your emails from being delivered entirely. Using an email and bounce checker is
one of the best ways to prevent this from happening and to safeguard your sender reputation.

How do I check if an email is valid?

NeverBounce’s free email address checker makes it easy to confirm an address’ validity. Our Real-Time Email Verification tool integrates with a range of platforms, allowing you to link it to newsletter signup forms, contact forms, lead forms, mobile apps, and much more. Easily verify single or bulk emails with our API, JavaScript widget, Webhook, or Dashboard!

What is a valid email address?

A valid email address is simply one that will receive emails. For instance, perhaps a subscriber signs up for your newsletter with their work email address. While they are still employed at the company, the address is considered valid. However, if they leave the company, that address may “go dead,” making it invalid.

Other Useful Steps to Improve Email Deliverability

Making sure your emails are properly delivered is important. Thus, senders should also consider taking these steps before sending emails to followers:

SMTP Test

Included with NeverBounce
An SMTP test helps identify the cause of deliverability problems. This is useful if your emails are not reaching subscribers, but you don’t know why. With an SMTP test, you can get diagnostic information about your SMTP server setup and identify potential misconfigurations that may impact your ability to send or receive email.

MX Records Test

Included with NeverBounce
An SMTP test helps identify the cause of deliverability problems. This is useful if your emails are not reaching subscribers, but you don’t know why. With an SMTP test, you can get diagnostic information about your SMTP server setup and identify potential misconfigurations that may impact your ability to send or receive email.

DKIM check

A DKIM check tests a domain to confirm it is setup correctly. A DKIM is a virtual signature that is generated by the sending mail transfer agent and decoded by the receiving MTA. If the values match, it is a sign that the email is secure and therefore helps reduce the spam score. Alternatively, if the DKIM headers do not match up, it is likely to be quarantined into a spam folder or otherwise marked as insecure.
By taking these steps and using NeverBounce, you’ll be much more likely to consistently deliver emails. Luckily, our single email checker is both thorough and efficient. All you have to do is integrate it with your platform to ensure anyone who signs up for your newsletter is actually providing a valid address. This is important in the competitive field of email marketing.
