What Is Email Checking?

Now, you may be asking, what is email checking? Well, let us explain it to you in the simplest way possible.

What Is Email Checking?

Email checking is a vital component of starting an email marketing campaign in the digital world.

Simply put, email validation involves the process of checking email addresses for syntax, domain, and deliverable mailboxes to help you keep your email lists clean and valid to increase your marketing effectiveness.

As a marketer, if you’re looking to boost your marketing campaigns, you should search for an effective and successful confirmation email so that you can acquire the necessary skills in this field.

Best Practices for Email Checking

Effective email validation requires following best practices developed through marketers’ collection experience and expertise worldwide.

These methods include:

1. Choose a Valid Confirmation Email Service:

Not all verification services are equally reliable, so it’s essential to do thorough research before choosing one.

This ensures you partner with reliable email checker sites that deliver accurate results and work well.

2. Regularly Verify Your Email Address List:

While periodic verification can instantly increase your deliverability, it’s important to understand that email addresses can change or become inactive over time.

Therefore, periodic verification is necessary to maintain a consistently high delivery rate.

3. Perform Initial Verification during Address Collection:

Including a simple syntax check in your signup form can significantly improve the quality of your email list.

By verifying Gmail addresses upon entry, you can decrease the occurrence of invalid or mistyped addresses, leading to a more significant proportion of valid Gmail addresses.

4. Avoid Sending Confirmation Messages:

Legitimate verification services don’t send validation emails because such messages can negatively affect your sender’s reputation score.

Instead, rely on dedicated verification services to authenticate without compromising your email deliverability.

5. Safeguard Customers’ Personal Information:

It’s your responsibility as a marketer or business owner to protect the personal information collected from your clients, like their email addresses.

So try to take appropriate measures to prevent unwanted disclosure or unauthorized access to this data, ensure compliance with privacy regulations, and build trust with your audience.

By adhering to these recommended methods, you can enhance the effectiveness of email validation, boost delivery rates, and uphold the integrity of your customer data.

In this age of digital marketing, while maintaining an email list hygiene may not be the most attractive task, it can have a significant impact on your personal brand growth.

In fact, checking your emails regularly can have many benefits. So, let’s explore why email checking is more than just a routine.

1. It Improves Email Deliverability & Data Integrity:

Implementing proper email validation methods ensures that hard bounces remain low, even as your email lists grow.

This ensures a high level of deliverability and guarantees that your emails are delivered to the intended recipients’ inboxes instead of being marked as spam.

2. It Enhances Lead Generation Campaigns:

Collecting valid first-party data is crucial for the success of email marketing lead-generation campaigns.

By validating email addresses, you can ensure that the data you collect is accurate and reliable, increasing the effectiveness of your cold email campaigns.

According to a study by Snov.io, in 2023, there will be a 4.3% increase in emails sent and received per day, and about 89% of marketers will use email marketing as their first marketing channel, so accessing a verified email list is critical.

3. It Prevents Blacklisting:

Email validation is a preventative measure to identify and remove invalid or suspicious email addresses from your list.

This helps protect your domain from being blacklisted, which can have a negative impact on your email deliverability.

4. It Avoids Risky Email Addresses:

Email confirmation helps detect and remove suspicious email addresses from your list.

By blocking phishing campaigns or social engineering attacks, you can safeguard your marketing efforts and protect your contacts from potential threats.

5. It Obtains Accurate Data:

Regularly cleaning your email lists by eliminating spammy, outdated, and undeliverable email addresses ensures that your data remains accurate and free from unwanted contacts over time.

This raises the likelihood of your emails reaching your contacts’ inboxes and enhances the accuracy of your data.

6. It Boosts Sender Reputation:

Email checking reduces bounce rates, which is essential for maintaining a positive sender reputation.

A good sender reputation enhances the likelihood of your emails being delivered successfully and increases the trustworthiness of your domain.

7. It Reduces Spam Complaints:

By removing invalid addresses from your database, you can enhance your email deliverability and establish a positive reputation with email service providers (ESPs) and internet service providers (ISPs), thereby reducing the number of spam complaints.

This decreases the likelihood of your email addresses being marked as spam.

8. It Stops Catch-All & Temporary Accounts:

Advanced email verification tools include features to detect catch-all and temporary email accounts.

You can improve engagement rates and target genuine contacts by ensuring that your emails resonate with real people.

9. It Increases Engagement Rates:

Validating email addresses ensures that you have genuine contacts, increasing the likelihood of engagement and interaction with your emails.

By reaching more contacts with accurate email addresses, you can improve the effectiveness of your email marketing campaigns.

10. It Achieves Higher ROI:

Email checking helps you avoid sending emails to non-existent addresses or domains that can’t receive messages, ultimately leading to a higher return on investment (ROI).

As a matter of fact, according to Emailable, email verification boosts ROI by increasing money earned and by decreasing money spent.

Overall, by eliminating these invalid addresses, you can reduce bounce rates and increase conversion rates, ultimately maximizing your ROI.

How to Check an Email Address?

How to Check an Email Address?

As spammers have become highly skilled in their tactics, you, as a professional marketer, must acquire the skill of email checking to distinguish between genuine and fake email address lists.

If you need to learn how to check your email addresses, don’t worry! Here are five simple ways to verify the validity of an email that are both user-friendly and can be implemented by everyone.

Let’s get started!

#1 Method. Sending an Email to the Owner of the Email Address:

You can determine if the email address is valid by sending a message to the email address and seeing if it receives a non-delivery notification.

However, keep in mind that some email provider services use global addresses so that you may need a clearer indication in these cases.

As such, this technique is highly effective for marketers in the early stages and with a limited marketing database.

It’s also a favorable option if you only incorporate a handful of new email addresses to your list monthly.

#2 Method. Trying to Recover Old Email Address Password:

Major email provider services such as Google, Hotmail, and Yahoo have account recovery processes that can help verify the existence of an email address.

You can check its validity by entering the email address on the relevant recovery pages.

#3 Method. Performing IP Address Search:

By performing an IP address lookup on the IP address of the server the email originated from, you can determine its geographic location and ISP or associated organization.

However, this method doesn’t provide information about deliverability or domain reputation.

#4 Method. Looking up Email Addresses in Search Engines:

Searching for the email address in search engines such as Google or Bing can help confirm its existence.

Accurate and real email addresses belonging to people with an online presence are more likely to appear in search results.

#5 Method. Email Checking Tools:

Email verification websites and companies are online and accessible services that can verify email addresses in bulk or free in the shortest possible time.

These tools can accurately check the validity of an email address, but some services may have limitations or require paid subscriptions to verify larger volumes of addresses.

Now, if you want to know how to choose an email verifier service that fits your needs and resources, continue our article.
