Increase marketing
campaign results
In email marketing, it is important that the emails you send are verified, validated, and
received by customers. 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 and utilizing
email verification and email validation tools you can increase your sender score and email
campaign quality.
Verify email address of new user registrations
Ensuring the users who sign up on your website have a valid and verified email address is
valuable for a number of reasons:
- Catch user typos with email validation when they’re entering their email address and prompt the user to fix typos before allowing them to register.
- Lets you stay in touch with your users knowing you have a verifiable email address for: credit card expiration, receipts, new features and offerings, etc.
- Ensures that your users can reset their password securely if forgotten: without email address verification and validation, there’s no way to validate someone’s identity outside of manual human verification.
Segment potentially
dangerous emails
Prevent users from signing up for your website with disposable email addresses using our
email validation API tool. Users who sign up for these services are usually try to bypass giving you their
real email for a specific reason: maybe they want to abuse your freemium features, etc.
By ensuring you only allow users with real verifiable personal or business email addresses
to register, you reduce the risk for abuse on your website.
