5 Reasons: Why Email Verification is crucial in email marketing

Emails have become a crucial part of modern business communication, and for salespeople, it is one of the primary tools for reaching out to potential customers. However, these days, just having or buying a large email list is not enough. The quality of the email addresses in the list is just as important as the quantity.

That’s where the email verification comes in.

Email verification, also known as email validation or email checking, is the process of ensuring that an email address is valid and belongs to a real person. This involves verifying the format of the email address, checking that the domain name is valid, and ensuring that the email address is not a fake or disposable email address.

Below we summarized Top-5 reasons why email verification is so important in email marketing:

1. Email verification improves email deliverability

Email verification helps improve email deliverability by ensuring that the email addresses on your list are accurate and up-to-date. Invalid or non-existent email addresses can result in emails bouncing back, which can negatively impact your email deliverability. By verifying your email addresses, you can reduce the number of invalid email addresses which improves your email deliverability.

Email deliverability is key for email marketing because it determines whether or not your emails reach the inbox of your target audience. If your emails have a low deliverability rate, they may be marked as spam, and your target audience may not receive them. This can result in missed opportunities for engagement and sales, and it can also harm your email reputation.

Having a high email deliverability rate means that more of your emails are reaching the inbox of your target audience, which can increase the chances of engagement and sales. Email deliverability is also a crucial factor in determining the success of an email marketing campaign, as it affects the reach and impact of your messages.

In short, email verification is essential for successful email marketing campaigns.

2. Email verification increases the accuracy of your data

Inaccurate data is a major problem for salespeople, and it can be costly. By verifying email addresses, you can be sure that the information you have is accurate and up-to-date. This means that you can avoid sending emails to old or invalid email addresses, and you can focus on sending emails to the right people at the right time.

Email verification plays a crucial role in populating a salesperson’s email marketing outreach list. By verifying the email addresses on the list, the salesperson can ensure that their email marketing campaigns reach the inboxes of their target audience.

When a salesperson is compiling their email marketing outreach list, they may come across a large number of invalid email addresses, containing typos, incorrect domains, and spam-catching or generic emails (like info@ or contact@). These addresses can result in emails bouncing back and negatively impacting the salesperson’s email deliverability.

Email verification can help identify these invalid email addresses and remove them from the outreach list, which can improve the accuracy of the data. This can then increase the chances of success for email marketing campaigns, as the salesperson will be able to reach their target audience more effectively.

In addition, email verification can also help a salesperson identify and remove duplicates or outdated email addresses, which can help avoid sending multiple emails to the same person or to individuals who are no longer interested in the product or service being offered.

3. Save time and money

Email verification saves time and money for email marketing campaigns by reducing the number of invalid or non-existent email addresses on a salesperson’s outreach list. When a salesperson sends emails to invalid email addresses, they waste valuable time and resources, as these emails will bounce back and not reach their intended recipients. More importantly, all major email marketing automation tools have their subscription prices based on the number of contacts. And they don’t care if the contacts are valid or not. According to Grabaro, roughly 30% of all emails from purchased contact lists are invalid. Now imagine paying for a subscription that requires 30% more contacts than needed. Doesn’t sound great, right?

Additionally, sending emails to invalid or non-existent email addresses can harm the salesperson’s email reputation and deliverability, which can negatively impact the success of future email marketing campaigns. By verifying the email addresses on their outreach list, a salesperson can avoid these costly mistakes and improve their email deliverability. Getting blocked by major spam filter providers can be extremely costly, as they are typically affecting the entire domain of a firm. Now imagine that all @yourfirm emails are marked as spam across the board. Also not cool. The cost of getting out of spam filters will be in the 5-digit US$ range.

4. Email validation improves the reputation of your own email

When you send emails to invalid addresses, it can hurt your email reputation. This can lead to your emails being marked as spam and not reaching the inbox of your potential customers. Email verification can help you avoid this by reducing the number of invalid email addresses in your list and improving the accuracy of your data. This can improve your email reputation and increase the chances that your emails will reach the inbox of your potential customers.

5. Checking the recipient’s email in advance enhances customer experience

Email validation can enhance the customer experience by ensuring that you are sending emails to real people who are interested in your product or service. This means that you can send targeted and relevant emails to your potential customers, which can improve their experience and increase the chances that they will make a purchase.


Email verification is an important tool for salespeople. It helps improve email deliverability, increase the accuracy of your data, save time and money, improve your email reputation, and enhance the customer experience. If you want to be successful as a salesperson, it is essential to verify your email list and ensure that your emails reach the right people at the right time.
