How many of the emails sitting in your marketing system right now are outdated or, worse, a threat to the deliverability of your costly campaigns?

You may be shocked to know it could be 30% or more, as that’s how many emails go bad after just a single year.

If you want to level up the impact of your email marketing efforts, you have to turn your attention to email verification tooling.

Let’s explore email verification and how to choose the best tool to automate the heavy lift of keeping your lists clean so you can create marketing that matters.

First Up: What’s Email Validation, Exactly?

Email validation is the process of checking if an email address is real, active, and can be delivered to.

This is a crucial step in businesses that run email campaigns, as it helps ensure the accuracy and effectiveness of their marketing efforts.

Here are some of the tasks email validation tooling can perform to help you with email list management:

  • Syntax Check: This verifies that an email address follows a known format without formatting issues, misspellings, etc.
  • DKIM Test: Sending DomainKeys Identified Mail (DKIM) tests a domain to confirm it is configured correctly by adding a digital signature to sent emails, and checking if it’s decoded correctly on the other end.
  • SMTP Verification: Simple mail transfer protocol (SMTP) is used by servers to relay emails. An SMTP test makes sure your SMTP server setup is optimized for deliverability.
  • MX Record Scan: Mail exchange (MX) records specify the mail servers responsible for receiving email messages. An MX record validation makes sure the records are pointing to a server that is configured to receive email.
  • Disposable Email Check: Disposable email addresses (like are often just used for short-term purposes, making them clutter in your marketing platforms. Many companies and websites block such addresses to reduce spam and maintain a clean email list.
  • Spam Trap Detection: Spam traps are email addresses set up specifically to catch spammers. Sending emails to these addresses can lead to severe deliverability issues.
  • DNSBL Identification: Domain name system blacklist monitoring (DNSBL monitoring) looks to see if the domain or IP address associated with an email is listed on any DNS-based blacklists. When you deliver to these, it can hurt your sender reputation.
  • Catch-All and Role-Based Email Elimination: Some marketing teams don’t want to spend more than they have to sending emails to addresses that aren’t associated with real people. For this reason, some choose to sort out emails with “support” or “contact” in their name.

Why Should I Choose an Email Validation Tool?

Using an email validation tool offers several significant benefits for businesses that rely on email communication, especially for marketing purposes.

Improve Deliverability Rates

Email validation helps ensure that your emails are delivered to valid and active addresses. This reduces the likelihood of emails bouncing back.

Considering the price and time associated with maintaining email lists and sending well-crafted email messages, a high bounce rate isn’t only a morale killer — it’s a budget buster and worse.

Protect Your Sender Reputation

Another thing about email bounces is that they can harm your sender reputation. This is a metric internet service providers (ISPs) use to score email domains.

A good sender reputation is crucial for email deliverability. Sending emails to inactive or invalid email addresses that bounce can get you marked as a spammer and lower your sender score. The lower your score, the more likely your emails will be locked in a vicious cycle of being marked as spam and diverted before they ever hit inboxes

Enhance Customer Engagement

If you measure the success of your email campaigns based on engagement, it’s critical you’re measuring based on emails that are actually getting delivered to and opened by real people.

Sending emails to active, engaged subscribers who want to receive them leads to higher interaction rates and better email marketing performance.

Increase ROI on Email Marketing Campaigns

Over time, email lists can accumulate a lot of invalid or inactive addresses.

Every time you store or send an email to an address like this, that’s money down the drain.

But the answer isn’t wasting a bunch of valuable employee time combing through emails. Manually checking and cleaning email lists can be time consuming and prone to human error.

Email verification tools automate this process, allowing you to focus on strategic aspects of email marketing while still improving your delivery rate — all of which lead to higher marketing return on investment (ROI).

Ensure Compliance

Email service providers (ESPs) often have strict policies regarding email list quality.

Using an email validation tool helps ensure that you meet their requirements, reducing the risk of your emails being flagged or blocked and your sender score being degraded.

Overall, using an email validation tool is a proactive and essential step for maintaining a healthy email marketing list and strategy.
