Why Verify Email Addresses?

Verifying emails can make a big difference in the success of your outreach efforts. Let's break down why email verification is so important.

Improved deliverability. When you verify email addresses, you make sure that you're sending emails to valid, working addresses. This means your messages are more likely to reach real people. Without verification, your emails could end up in non-existent inboxes, wasting your efforts.

Improved sender reputation. Your sender reputation is a score that Internet Service Providers (ISPs) and email services use to decide if your emails should go to the inbox or the spam folder. If you send emails to a lot of invalid addresses, your emails might bounce back, hurting your sender's reputation. So, a bad reputation can make it harder for your future emails to get through. In other words, verifying emails helps keep your bounce rate low and your sender's reputation strong.

Higher engagement rates. Sending emails to verified addresses means your messages are more likely to be read by the right people. When your emails land in the correct inboxes, they have a better chance of being opened and acted upon. This leads to more engagement and higher chances of converting leads into customers.

Why Email Verification Matters?

Skipping email verification can cause several problems that can seriously hurt your sales outreach efforts. If you're new to this, here's a simple explanation of what can go wrong without email verification.

Increased Bounce Rate

When you send emails to addresses that don't exist, those emails bounce back to you. This is known as a "bounce rate." A high bounce rate means many of your emails are not getting through. This not only wastes your efforts but also harms your sender's reputation. A poor sender reputation can make it harder for your future emails to reach anyone's inbox.

Wasted Resources

Creating a good email takes time and effort. If you send these emails to invalid addresses, all that hard work goes to waste. You're spending time crafting messages that no one will ever see, which means you're using up resources without any chance of getting new leads or making sales.

Lower Engagement

For your emails to be effective, they need to be seen and read by the right people. If your emails don't reach their intended recipients, you won't get any responses. This lack of engagement makes it difficult to achieve your sales goals because fewer people are interacting with your messages.

Damaged Brand Reputation

Constantly sending emails to invalid or uninterested recipients can lead to people marking your emails as spam. This can damage your brand's reputation. When people think of your brand as a source of spam, they're less likely to trust you or buy from you in the future.

By not verifying your email addresses, you risk higher bounce rates, wasted resources, lower engagement, and a damaged brand reputation. These challenges can significantly hinder your sales outreach and overall success.

Advantages of Using Email Verification

Email verification is a key step in making sure your email marketing campaigns are successful. Here’s an explanation of the benefits you get from verifying email addresses.

Minimize Email Bounces

Email bounces occur when emails can’t be delivered. This can happen because of typos, outdated information, or fake email addresses.

When many of your emails bounce back, it hurts your sender's reputation. A poor reputation can make it harder for your future emails to get delivered, meaning fewer people will see your messages.

If you verify your email address before you send your campaigns, you can reduce the number of bounces. This means your emails are more likely to reach real inboxes, improving your chances of engagement.

Improve Sender Reputation & Deliverability

Sender reputation is a score that ISPs and email services assign to you based on how often your emails bounce, get marked as spam, or receive low engagement. A good reputation means your emails are more likely to be delivered.

Using email verification helps improve your sender reputation by reducing bounce rates and ensuring you’re sending emails to real and active addresses.

A better sender reputation means your emails are more likely to reach their intended recipients, leading to more positive interactions with your messages.

Boost Email Campaign Results

The success of your email campaigns can be measured by open rates, click-through rates, conversion rates, and overall return on investment (ROI).

When you verify emails, your messages are more likely to reach valid and interested recipients. This leads to higher engagement with your emails.

Improved campaign results mean more people are opening, clicking, and acting on your emails, which boosts your engagement, conversions, and ROI.

Maintain Fresh Email Lists

Old email lists can result in high bounce rates, low engagement, and wasted effort on emails that don’t reach anyone.

Regularly updating your email list through verification helps keep it clean and current. This ensures your emails are delivered to active and interested recipients.

Moreover, having fresh email lists improves your campaign success by reaching people who are more likely to engage with your content.

Reduce Spam Complaints

If too many people mark your emails as spam, your sender's reputation suffers. This can lead to lower deliverability and even being blocked by email providers.

Best practices to reduce spam complaints are to verify email addresses, use a double opt-in process, and send relevant content to engaged recipients to avoid being flagged as spam.

By reducing spam complaints through verification, you maintain a healthy sender reputation and ensure high deliverability. This keeps your audience engaged and your campaigns effective.

6 Techniques for Email Verification

Ensuring your emails reach the right people is key to a successful email marketing campaign. Here's a guide to various techniques for verifying email addresses.

1. Verify Email Syntax

First, let's understand what email syntax is. Email syntax verification checks if the email address follows the correct format.

What are the standard email syntax rules: A valid email address looks like this:

It has three parts:

  • A unique identifier (XYZ), can include letters, numbers, and certain special characters such as (!, #, $, %).
  • An "@" symbol.
  • A domain name ( is often a business domain or an email service provider.

Steps for Email Syntax Verification:

  1. Gather the emails you want to verify.
  2. Run these emails through an email verification tool that includes syntax checking.
  3. The tool will highlight addresses with syntax errors.
  4. Fix the errors manually or contact the recipient for the correct address.
  5. Run the corrected addresses through the tool again to ensure all errors are resolved.
  6. Once all addresses pass the syntax check, you can use them in your campaign.

The next step is to ping the email server. Email server pinging checks if the server will accept the email address without sending an email.

2. Test with a Secondary Email Account

Using a secondary email account helps you test email deliverability without risking your primary account's reputation.

How to Set Up a Secondary Email Account:

  1. Create an Account: Use an email service like Gmail, Yahoo, or Outlook.
  2. Send Test Emails: Send emails from this account to your list.
  3. Monitor Results: Check bounce rates and responses.
  4. Clean Up: Remove invalid addresses from your main list based on these results.
  5. Send Campaigns: Use your primary account to send your verified emails.

3. Perform DNS Lookup

DNS (Domain Name System) records link domain names to IP addresses and provide details about mail servers (MX records) and other domain-related information.

Steps for Conducting a DNS Lookup:

  1. Use a DNS Tool: Open a tool like MXToolbox DNS Check.
  2. Enter Domain Name: Type the recipient’s domain name and run the check.
  3. Review Results: Check the DNS records for validity.
  4. Verify: If no details appear, the domain might be invalid.

DNS lookup helps confirm domain authenticity but should be used alongside other methods for best results.

4. Conduct IP Address Lookup

The role of IP addresses is to help verify the legitimacy of email servers and reveal information about potential spam or malicious activity.

Steps for Conducting an IP Address Lookup:

  1. Find IP Address: Use the email’s domain to get its IP address.
  2. Use a Lookup Tool: Enter the IP address using a tool.
  3. Review Information: Check the IP address's location, reputation, and associated domain.
