Many marketers face this issue of their emails not landing into the inbox of your recipients. One evident reason can be that your email list is not verified. In case you are running a cold email outreach then it is essential for running a successful campaign that you verify email address in your email list.

In this article, we’ll look at practical methods for email list verification so that your communications get to the appropriate individuals and increase your chances of success.

Let’s first clarify what email list verification is and why it matters so much for your sales outreach before moving on.

What is email verification?

An essential first step in cold email outreach is verifying an email list. It is a procedure for verifying and validating incorrect or invalid emails that are included in the list.

Email verification has two purposes:

1) Its first goal is to confirm that the email addresses are legitimate.

2) It makes connections with real email accounts more likely.

By eliminating the spammy and invalid email addresses, your cold-email campaign can proceed with greater security.

After learning the fundamentals of email list verification, let’s examine why it’s an essential stage in your outreach procedure.

How can email verification decrease your bounce rate and improve email deliverability?

Several methods are employed by email verification services to validate your email address. They verify that the email address is valid and appropriately formatted, the mailbox is operational, and the domain is present. Email verification lowers the likelihood of bounces by preventing invalid or improperly structured email addresses from being used in email campaigns.

Email addresses that are likely to cause hard bounces are flagged and removed through email verification. A decreased bounce rate is achieved by removing these addresses from the mailing list, which reduces the possibility of hard bounces.

Why should you verify your emails for your cold email outreach?

Getting the intended recipients’ emails is the initial step in sending cold emails. Nonetheless, a lot of pros skip over this email list verification stage and go straight into outreach. You should confirm your email list before sending out unsolicited emails for the following reasons:

1) Assists in preventing email bounce rates

When it comes to cold email campaigns, email bounces are a real nightmare. They could harm the legitimacy of your email account and harm the reputation of your domain. In the worst situation, email service providers (ESPs) may potentially ban you or put you on the hated spam list.

However, you can separate the quality contacts from the junk ones when you validate your email list before launching those cold calls. And the outcome? a notable drop in the bounce rate of your emails and protection from those scary spam indexes. 

2) Guarantees email delivery and reputation 

You have a reputation to maintain for your email account. Your sender reputation score reveals your level of dependability and credibility. Your emails will get in your prospects’ inboxes more easily the higher your reputation score is. 

However, you are playing with fire if you are sending emails to invalid or spam-filled accounts on a regular basis. It could happen very rapidly, perhaps before you realize it, if your email account is suspended. Not what you want to find yourself in!

The clever process of verifying your email list makes sure that the proper people receive your emails in a genuine way, which improves your account’s reputation score and email deliverability. 

3) Refinement of the email list

Emails sent to invalid or inactive addresses are a waste of time and effort because of high bounce rates. Your sender reputation suffers, and your important communications are not delivered. Sending emails to inactive users on a regular basis also raises the possibility of their being tagged as spam, which will negatively impact your email deliverability.

By filtering out dormant or nonexistent email addresses, email verification makes sure the correct individuals see your outreach. That way, your email list is clear, streamlined, and free of erroneous email addresses.

This helps you concentrate your outreach efforts on prospects who are likely to engage by saving you money by preventing you from wasting it on sending emails to contacts who will never get them.

4) Reduces concerns about hitting spam folder

Sending emails to unverified addresses is akin to walking into a minefield of potential spam complaints. Your well-crafted emails might not reach the recipients you intend, which would lessen the effect of your cold outreach campaigns.

You don’t want to go down that route. You can find and eliminate accounts that pose a risk or are no longer active by putting your email list through the verification procedure. This implies that you are only emailing people who are genuinely interested in what you have to say and who are actively engaged.

5) Enhances your cold email outreach

When you verify your email list the list that you send becomes more legitimate. The email verification ensures the success of your cold email outreach efforts. You can establish connections with interested parties who are more likely to read, open, and reply to your emails. This translates to higher engagement levels, improved conversion rates, and ultimately better outreach campaign outcomes.

When should you verify your emails?

It is crucial that you verify the legitimacy of each email address in your list. Many experts neglect to validate email lists, which can lead to increased bounce rates and, in severe situations, account suspensions. The following three situations indicate that you ought to confirm your email addresses:

1) Your email list has been updated

Verifying the list in advance is highly advised if you intend to start a fresh cold email campaign with a brand-new one. Contact information on a fresh list, particularly one with a lot of data, can be inaccurate, spammy, or invalid. This can negatively impact the effectiveness of your outreach. This guarantees that your list is clear, legitimate, and actionable from the outset. You can send the email with confidence after verifying the list.

2) Your email bounce rate is continuously rising

A consistent increase in your bounce rate is a warning sign that something is wrong. Don’t disregard it! It’s time to examine this more closely. We wish to prevent your email account from suffering from an excessive amount of bounce backs.

It is essential to review your email contacts and remove any invalid ones in order to avoid any unfavorable outcomes.  You may be certain that you are only addressing reachable and active individuals by double-checking the email addresses on your list. Finding and eliminating any invalid or nonexistent addresses is a proactive measure. 

By doing this, you’ll be able to better regulate your bounce rate and guarantee delivery.

3) You haven’t checked your periodic email list in a while

An email list degrades yearly. Therefore, it’s wise to incorporate email list verification on a regular basis into your outreach strategy. Email list verification should be done at least twice a year, preferably every three months.

Your contact lists may get disorganized when someone quits their job or deletes their email account. This is when regularly verifying emails comes in handy. You’re really helping yourself when you periodically review and purge obsolete listings of incorrect addresses.

This procedure not only keeps your sender credible, but it also guarantees that your outreach campaigns provide fruitful outcomes each and every time. Thus, develop the habit of routinely validating those email addresses to ensure that your campaigns are running smoothly!

How to use email verification tool?

The next step is to confirm that the email addresses on your list of potential customers are real and active. Usually, email address verification entails determining whether the address is current and legitimate. There are many methods available for email address verification. Here are some of the methods:

1) Using an email verification tool

There are many free email checker tools available in the market that can help you check invalid addresses but for an accurate analysis it’s best to choose a software which has the best email verification technology.

2) Checking the email syntax

Errors in syntax and typography are the most frequent problems relating to email addresses. They need to be manually reviewed and corrected. Three components make up a common email address: a domain name, a unique identifier, and the “@” sign. This sample will help you better comprehend syntax errors.

Now let’s examine the email address “[email protected].”

Here, “abc” stands for the email’s unique identification. It can contain numbers from 0 to 9, uppercase and lowercase English letters, and special characters like “! # $ & %’* + – / =? ^ _ } | {.” It can’t have more than 64 characters.

The domain name, which may be something like “” or “,” is referred to by the “@def” part.

Additionally, make sure an email address follows the above-mentioned syntax; if it doesn’t, the emails will “bounce back” or be returned. Errors like “” instead of “” should also be avoided as they can also result in emails being returned.

3) Get Rid of All Emails, Throwaway and Catch-All

Email marketing yields little benefit from disposable addresses. Catch-all emails, which receive messages sent to the wrong address, are comparable in this regard.

Role-based mail accounts like admin@ or info@ and spam detection traps are examples of other valid but unwanted address types. If you send messages to these addresses, your address may be blocked.

4) Verify the email address.

The verification of DNS records for domain names comes next. Finding out if the domain name has a valid MX record is the aim. The MX record specifies the email server responsible for receiving messages for a domain name. If a domain lacks a valid MX record, it gets detected and removed from the mailing list.

MX Toolbox is one well-liked DNS checking tool. When the domain name “” is typed, the following details are displayed: DNS record discovered. And when you type in the domain name “gmail.comm,” this is what it shows: We apologies for not being able to locate any name servers for ‘gmail.comm’.

5) Searching for an IP address

Make that the email address is associated with a legitimate, registered, and operational domain when using IP address verification to confirm emails. This is crucial since email addresses can change due to domain expiration or company domain switches.

The verification service explicitly verifies the MX records throughout this procedure and looks over the domain name’s DNS records. This makes it easier to verify that the domain can efficiently receive emails.

Here’s how to go about it:

Step 1: Launch MXToolbox in your web browser first.

Step 2: Type your domain name in the text field provided, fully qualified, and click DNS Lookup.

Step 3: A list of IP addresses connected to the domain will be provided to you.

Any IP address on the list is yours to select.

We will begin with the IP address lookup in the following step. Numerous IP address lookup programmes, such as whatismyipaddress, are available online and can yield the recipient’s email server’s IP address.
Examine the offered location servers and ISP information after you get the lookup results. This data can provide you with insightful knowledge. Anything out of the ordinary or suspicious could be a sign of email spoofing, in which case using that specific email address could be dangerous.

You may complete all of the technical checks with just one click with the aid of an email validation tool.

6) DNS query

DNS lookup is a procedure you can use to find out which email server will accept emails for a given domain name. It’s similar to requesting data from a DNS server, especially the MX record that identifies the domain’s email server.

These are the steps you can take to do a DNS lookup:
Step 1: Use your browser to launch the MXToolbox DNS Check.

Step 2: Type the domain name of the receiver into the assigned text field.

Step 3: Press the button to verify the DNS. A list of hostnames together with the DNS record data for each will be sent to you.

The domain may not be available or may not have any DNS records in place if you are unable to see any details for the given domain.

(As you can see from the image below, which shows no entries, it’s likely that the domain doesn’t exist.)

Note: Because of cached data, DNS propagation delays, and possible DNS record misconfigurations, the DNS lookup mechanism could not be entirely dependable. Consequently, email deliverability may be impacted.

Some of the Best Methods to Verify an Email Address

There are three things you need to take into account while searching for a trustworthy and effective method of email list verification:

1) Efficiency of time and sender reputation

Although sending emails from many accounts and verifying the syntax of emails may seem easy, they actually require a lot of manual labor and can take a long time. You could be doing more useful outreach work with all the time and energy you spend on these things.

2) Intricacy

Pinging servers and looking up IP addresses and DNS addresses are technical operations requiring a certain degree of knowledge. To be honest, a salesperson shouldn’t be bogged down in technical responsibilities; instead, they should be concentrating on developing relationships and closing deals.

3) Economy of scale

Purchasing an email verification product is an extra cost, particularly if you are currently utilizing an email outreach platform. It may seem like an expensive extra that is needless to have. Furthermore, it might be somewhat stressful to switch between the two distinct duties (for real!). Therefore, the best course of action is to look into a cold email outreach service that includes email verification as a feature. 

It’s comparable to shooting one arrow at two birds.

1) Reducing the time spent on email validation

2) Expanding the outreach campaign and adding a number of other useful components.
