Email Validation for Failure Control and Limitations

What is Email Validation?

Email validation is a preventive measure used to reduce email delivery failures. It helps identify incorrect, invalid, or non-existent email addresses before an email is triggered.

Important Disclaimer

Email validation does not guarantee email delivery and cannot confirm ownership or control of an email address.

No email service provider or validation system can offer 100% accurate validation results.

What Email Validation Can Do

• Detect invalid email formats

• Identify non-existent or incorrect email addresses

• Reduce hard bounces caused by obvious errors

• Prevent emails from being triggered to clearly invalid addresses

Prevent failures caused by:

• Temporary server issues

• Full inboxes

• Spam filtering or blocking

• Recipient-side restrictions

• Best Practices & Responsibility of the Sender

• Ensure that emails are triggered only to your registered and consented audience
  

Avoid sending emails to:

• Old or outdated user data

• Users who are no longer associated with your services

• Users who are no longer interested or have disengaged

• Regularly clean and update your contact database

• Do not rely solely on validation for deliverability—maintain proper list hygiene and consent practices

Note:

Email validation is a supportive tool, not a guarantee. It helps minimize failures by filtering out invalid addresses, but the responsibility of sending emails to the right, updated, and consented audience lies with the sender.
