In email marketing, it is important that the emails you send to your clients are
received by them. One of the most common causes of bounced emails is sending to
unverified email addresses. Email campaign providers may close the business account
when emails regularly bounce. By eliminating bounced emails you can increase your
sender score and email campaign quality.

Ensuring the users who sign up for your website have a valid email address is
valuable for a number of reasons:
- You can catch user typos when they’re entering their email address and prompt the user to fix them before allowing them to register.
- It lets you stay in touch with your users: you can email them when their credit card expires, when you send them receipts, when you have new features available, etc.
- It ensures your users can reset their password securely if they ever forget it: without an email address there’s no way to validate someone’s identity outside of manual, human verification.
