Email Validity Check: Boost Deliverability & List Hygiene
Valeria
/ Updated 07 may
In today's digital world, email marketing remains a powerful tool for businesses. However, the success of your email campaigns hinges on the accuracy of your email list. Using email validity checkers ensures that you're sending messages to real, active inboxes, maximizing your reach and minimizing wasted efforts. This article explores the importance of email validity checks and provides practical methods for maintaining a clean and effective email list.
Did you know that approximately 20% of email addresses become invalid each year due to job changes, typos, or simply users abandoning old accounts? According to a recent study by ReturnPath, poor data quality is a leading cause of deliverability issues, impacting up to 10% of marketing revenue. Using an email validity checker can significantly mitigate these risks, ensuring your messages reach their intended audience and your marketing efforts are not wasted. Regularly checking to check whether email is valid is crucial for maintaining a healthy email list.
Why Check Whether Email is Valid?
Verifying email addresses is crucial for several reasons.
It helps to improve deliverability and maintain a strong sender reputation.
Additionally, it ensures that your marketing efforts are directed towards engaged and reachable recipients.
Reducing Bounce Rates and Improving Deliverability
High bounce rates can significantly impact your email deliverability.
When you send emails to invalid addresses, these emails bounce back, signaling to email providers that your sending practices might be questionable.
This can lead to your emails being marked as spam or even your IP address being blacklisted. By using an email validity checker, you can reduce bounce rates and improve your chances of landing in the inbox.
Maintaining a Clean and Engaged Email List
A clean email list is a healthy email list.
Regularly removing invalid or inactive email addresses ensures that your messages are reaching people who are genuinely interested in your content.
This, in turn, can lead to higher engagement rates, such as opens and clicks, and ultimately improve your ROI.
Protecting Sender Reputation and Avoiding Blacklists
Your sender reputation is a critical factor in email deliverability.
Email providers use your sender reputation to determine whether your emails should be delivered to the inbox or filtered as spam.
Sending emails to invalid addresses can damage your sender reputation, increasing the likelihood of being blacklisted. Regularly check whether email is valid to safeguard your sender reputation.
Think of your sender reputation as your credit score for email. Just as a low credit score can prevent you from getting a loan, a poor sender reputation can prevent your emails from reaching the inbox. Email providers like Gmail and Outlook constantly monitor sender behavior, including bounce rates, spam complaints, and engagement metrics. High bounce rates, often caused by sending to invalid email addresses, are a major red flag. Therefore, it's essential to check whether email is valid regularly to maintain a positive sender reputation and ensure optimal deliverability.
Methods to Check Whether Email is Valid
There are several methods to verify the validity of email addresses, ranging from simple syntax checks to more advanced mailbox verification techniques.
Each method offers a different level of accuracy and can be used in combination for a more comprehensive validation process.
Syntax Verification: Ensuring Correct Email Format
The most basic level of email validation is syntax verification.
This involves checking whether the email address follows the correct format, such as containing an @ symbol and a valid domain extension.
While syntax verification can quickly identify obvious errors, it doesn't guarantee that the email address is actually active.
For example, an email address like 'john.doe@example.con' would be flagged by syntax verification because of the '.con' extension. However, syntax verification won't catch validly formatted but non-existent addresses like 'jane.doe@invalid-domain.com'. Therefore, it is important to use syntax verification as a first step, but it should not be the only step. It is a good way to check whether email is valid as a first pass.
Domain Existence Check: Verifying the Domain is Active
A domain existence check verifies that the domain name in the email address is active and registered.
This can be done by performing a DNS lookup to see if the domain has valid MX records.
If the domain doesn't exist or has invalid MX records, it's a strong indication that the email address is not valid.
Mailbox Existence Check: Confirming the Mailbox Exists
The most accurate method of email validation is a mailbox existence check.
This involves connecting to the mail server and attempting to verify whether the mailbox actually exists.
While this method provides the highest level of accuracy, it can be more complex to implement and may be subject to rate limits by email providers.
Free Email Test Tools and Resources
Several free email test tools are available online that can help you verify the validity of email addresses.
These tools typically offer basic syntax and domain checks and can be a good starting point for cleaning up your email list.
However, it's important to be aware of the limitations of these free services.
Overview of Popular Free Email Verification Services
Here are a few popular free email test services:
- MailTester.com: Provides a simple interface for checking email deliverability.
- Email Hippo's free email test: Offers basic email verification services.
- Hunter's Email Verifier: Checks the deliverability of email addresses.
Limitations of Free Email Validity Checkers
While free email test tools can be useful, they often have limitations in terms of accuracy and features.
They may not perform real-time mailbox verification or offer advanced features like integration with marketing automation platforms.
Additionally, free services may have usage limits or require you to create an account.
Paid Email Verification Services: A Deeper Dive
For more comprehensive and accurate email validation, consider using paid email verification services.
These services offer advanced features, higher accuracy rates, and integration with marketing automation platforms.
While they come at a cost, the benefits of improved deliverability and a cleaner email list can outweigh the investment.
Advanced Features and Accuracy of Paid Services
Paid email verification services offer a range of advanced features, such as real-time mailbox verification, spam trap detection, and risk scoring.
These features help to ensure that you're only sending emails to valid and engaged recipients, minimizing bounce rates and maximizing deliverability.
For instance, real-time mailbox verification checks the validity of an email address at the point of entry, preventing invalid addresses from ever entering your list. Spam trap detection identifies and removes known spam traps, which can severely damage your sender reputation. Risk scoring assigns a score to each email address based on its likelihood of being valid and engaged, allowing you to prioritize your marketing efforts. These features make it easier to check whether email is valid.
The accuracy rates of paid services are typically much higher than those of free tools.
Integration with Marketing Automation Platforms
Many paid email verification services offer seamless integration with popular marketing automation platforms like Mailchimp, HubSpot, and Marketo.
This allows you to automatically validate email addresses as they're added to your list, ensuring that your data is always clean and up-to-date.
Integration can save you time and effort by automating the email validation process.
Cost Considerations for Paid Email Validation
The cost of paid email validation services can vary depending on the number of email addresses you need to verify and the features you require.
Some services offer pay-as-you-go pricing, while others offer monthly or annual subscriptions.
Consider your budget and the size of your email list when choosing a paid email validation service.

| ZeroBounce | Pay-as-you-go, Subscription | AI-powered scoring, Email activity data |

Best Practices for Maintaining Email List Hygiene
Maintaining a clean email list is an ongoing process.
It requires regular effort to ensure that your data remains accurate and up-to-date.
By implementing the following best practices, you can keep your email list healthy and improve your email marketing performance.
Regularly Check Whether Email is Valid
Make it a habit to regularly check whether email is valid in your list.
This can be done on a weekly, monthly, or quarterly basis, depending on the size and activity of your list.
Regular validation helps to remove invalid addresses and prevent deliverability issues.
According to Experian, segmented email campaigns have 14.31% higher open rates and 100.95% higher click-through rates than non-segmented campaigns. By regularly validating your email list, you can ensure that your segmentation efforts are based on accurate data, leading to more effective targeting and higher engagement. Using tools like Scrupp to gather verified email addresses can further enhance your segmentation strategy.
Implementing a Double Opt-In Process
A double opt-in process requires new subscribers to confirm their email address before being added to your list.
This helps to ensure that the email address is valid and that the subscriber is genuinely interested in receiving your emails.
Double opt-in can significantly reduce the number of invalid addresses on your list.

While free email test tools can be helpful for basic email validation, they often have limitations in terms of accuracy and features.

For more comprehensive and reliable email validation, consider using a paid service. Scrupp, while not a direct email verification tool, ensures the email addresses you obtain are verified during the lead generation process.
