Sweep Emails

About Sweep Emails

Sweep Emails is an email validation API that checks email addresses in real time and identifies disposable or fake email providers. It returns a response indicating whether an email is valid and, if it is disposable, which provider was detected, and is positioned for use cases such as registration forms, fraud prevention, and reducing bounce rates in email marketing.

The service is aimed at businesses that collect user emails and want to filter out fraudulent signups, free-trial abuse, and invalid addresses before they affect deliverability or marketing spend. Integration is via a POST request to a REST endpoint, with code examples provided for cURL, JavaScript, Python, and Go. The provider states the service is GDPR and CCPA compliant and does not store email data after verification.

Pricing includes a free tier (500 checks/month, basic validation), a Standard plan at $4.99/month (1,900 checks/month, advanced validation, disposable email detection, email/live support), and a Professional plan at $11.99/month (6,500 checks/month, same feature set as Standard).
