Zeruh offers three main email verification options. You can verify individual email addresses one at a time using our single verification tool – ideal for quick checks or verifying addresses on sign-up forms. For larger needs, we provide bulk email list verification, where you can upload an entire list of contacts and have all addresses validated in one go. And for developers or SaaS platforms, Zeruh provides a powerful API, allowing you to integrate real-time email verification into your own applications or workflows.

Zeruh offers flexible, transparent pricing to fit different needs. We use a credit-based system in which each email verification costs one credit. You can purchase credits as needed (pay-as-you-go) or opt for a monthly subscription plan that provides a larger number of verifications at a discounted rate. There are no long-term contracts or hidden fees – you simply pay for what you need. We also offer a free trial with some complimentary credits for new users, and any credits you purchase do not expire, so you can use them at your own pace.

Absolutely. Zeruh offers a powerful RESTful API for real-time and bulk email verification. It’s easy to integrate—just grab your API key from the dashboard and follow our docs. The API returns clear JSON results (valid, invalid, disposable, etc.) and is secure, scalable, and fast for any workflow.

At Zeruh, we aim for the highest accuracy in email verification using advanced checks like SMTP validation and IP intelligence. While no service can guarantee 100% due to catch-all domains and other factors, we get as close as possible—and if we can’t verify an address, we’ll refund your credits.

Zeruh supports all common file formats for bulk email list uploads. You can upload your contact list as a CSV file (comma-separated values) or a text file (.txt). If your contacts are stored in another platform, you can export them to one of these supported formats or use our integration options to import the data directly.

Yes – using Zeruh will definitely help improve your email deliverability. By removing undeliverable addresses, disposable accounts, spam traps, and other risky contacts from your mailing list, you’ll drastically reduce your bounce rate and avoid the problems that come from sending to bad emails. Maintaining a clean list improves your sender reputation, which means email providers see you as a trustworthy sender. This leads to more of your messages reaching your recipients’ inboxes (instead of getting blocked or sent to spam). In short, Zeruh helps protect your sender reputation and ensures that your email campaigns achieve better inbox placement and engagement.
