Best Practices to Check Email Validity Online

In the age of digital marketing, to have effective email communication, you need to ensure the email addresses are valid.

This section explores the best practices to check email validity online. By following them, you can strengthen the security & reliability of your email exchanges.

Best Practices to Check Email Validity Online

1. Send a Confirmation Email:

When someone signs up or subscribes to your service, it’s important to send them a confirmation email to complete the account setup process.

This process guarantees that the email provided is legitimate and belongs to the individual.

For example, upon signing up for a social media platform like LinkedIn, you’ll receive an email requesting you to click on a verification link to check your email validity and enable your account.

2. Cleanse Email Addresses at Collection Points:

Ensure you validate and verify email addresses as soon as they are collected through lead magnets, contact forms, or any other means. This can go a long way in preventing fake or mistyped email addresses from entering your database.

For example, a company’s website has a LinkedIn newsletter signup form that automatically checks if the entered email address follows the correct format before allowing submission.

3. Regularly Update and Clean Legacy Databases:

Over time, email addresses can become inactive or obsolete. It’s crucial to regularly review and remove outdated or unused email addresses from your database to maintain its accuracy and deliverability.

For example, a marketing team conducts a quarterly review of their customer database for their prospecting campaigns and removes email addresses that have not engaged with their emails in the past year.

4. Identify and Handle Spam Traps:

Some email addresses are specifically created to catch spam. Detecting and avoiding these spam traps is essential to maintain a good sender reputation.

Analyze patterns and entry points to identify potential spam traps and adjust your messaging accordingly.

For example, an online retailer notices that certain email addresses consistently mark their promotional emails, like thank you emails, as spam. They investigate further and find that these addresses were used during a specific campaign targeting a particular audience segment.

5. Continuously Monitor Your Database:

As your email database grows, monitoring it regularly for any issues that could affect email deliverability becomes more critical.

Keep an eye out for bounces, spam complaints, and other indicators of potential problems.

For example, a software company uses email monitoring tools to track the performance of its email campaigns, including open rates, CTR rates, and bounce rates. They proactively address any deliverability issues that arise.

6. Identify and Remove Spam Complainers:

If certain recipients consistently mark your emails as spam, removing them from your mailing list is best.

This helps maintain a positive sender reputation and ensures your messages reach engaged and interested recipients.

For example, a nonprofit organization notices that a particular subscriber frequently marks their fundraising emails as spam. They decide to unsubscribe the individual from their mailing list to avoid further complaints.

7. Implement Email Address Typo Correction:

Even a small typo in an email address can render your message undeliverable. Consider using software or tools that automatically detect and correct common typos in email addresses to improve deliverability.

For example, an online booking platform prompts users to confirm their email address by asking them to re-enter it. If there is a discrepancy between the two entries, the system suggests a possible correction based on common typos.

8. Handle Role-Based Email Addresses Appropriately:

Decide how you want to handle email addresses associated with specific roles, such as or

Depending on your business and marketing goals, you may treat them differently than personal email addresses.

For example, a customer support software provider sends automated replies to role-based email addresses but prioritizes personalized responses for individual email addresses to provide a more tailored experience.

9. Regularly Review and Update Email Verification Service:

If you rely on a third-party service to verify and clean your email database, periodically evaluate its performance.

Ensure the service delivers on its promise of providing clean and deliverable email addresses.

For example, a marketing agency regularly assesses the accuracy and effectiveness of its chosen email verification service. If they find discrepancies or unsatisfactory results, they communicate their concerns to the service provider and seek improvements.

10. Hold Your Email Verification Service Accountable:

If your email verification service fails to meet expectations or deliver the promised results, don’t hesitate to address the issue with them.

Ensure that they rectify any shortcomings and provide the level of service you require.

For example, a company discovers that its email verification service has been marking valid email addresses as invalid, resulting in missed opportunities. They contact the service provider, express their concerns, and request immediate resolution.
