Terms of use

These terms govern access to Inboxiqo websites, apps, APIs, free tools, and email verification services.

Last updated: June 26, 2026

These terms govern access to Inboxiqo websites, apps, APIs, free tools, and email verification services.

Service scope

Inboxiqo provides email verification, deliverability diagnostics, DNS lookup tools, and related reporting. The service helps customers assess whether an email address, domain, or DNS configuration appears usable or risky.

Inboxiqo does not send marketing email for customers, operate mailing campaigns, harvest email addresses, sell email lists, or provide a tool for spam or unlawful outreach.

Permitted use

You may use Inboxiqo only for lawful business purposes and only for email addresses and data that you are authorized to process.

  • Verify customer, subscriber, prospect, or operational email addresses where you have a lawful basis.
  • Use API results to reduce bounces, protect sender reputation, and maintain clean contact data.
  • Keep your credentials, API keys, files, and account users under your control.

Prohibited use

You must not use Inboxiqo to support illegal, abusive, deceptive, or harmful activity.

  • Do not upload purchased, scraped, harvested, stolen, or unlawfully obtained lists.
  • Do not use the service to generate, guess, scrape, enrich, or harvest email addresses for spam.
  • Do not use verification results to send unsolicited bulk email, phishing, malware, fraud, harassment, or other unlawful messages.
  • Do not interfere with the service, bypass rate limits, abuse proxies, reverse engineer protected parts of the platform, or resell access without permission.

Accounts, plans, credits, and API access

You are responsible for activity under your account and API keys. Credits, plan limits, daily limits, monthly limits, concurrency controls, and marketplace rules may apply depending on how you access the service.

RapidAPI, Apify, or other marketplace usage may also be governed by the marketplace's own terms. If marketplace terms conflict with Inboxiqo rules for acceptable use, the stricter rule applies.

Accuracy and availability

Email verification is an evidence-based technical assessment. DNS, SMTP, catch-all behavior, greylisting, disposable status, server throttling, and remote mailbox policies can change at any time.

We work to provide useful results, but we do not guarantee that every result will be complete, current, or error-free, and we do not guarantee inbox placement, delivery, campaign performance, or revenue outcomes.

Customer data

You retain ownership of the email addresses, files, and other data you submit. You grant Inboxiqo the limited rights needed to process that data, provide verification results, maintain logs, prevent abuse, secure the service, and comply with law.

You are responsible for giving required notices and obtaining required permissions from the people whose data you submit.

No certification claim

Inboxiqo does not currently claim ISO, SOC 2, PCI, or similar formal security or compliance certification. We may describe practical security measures we use, but no certification should be inferred unless it is expressly listed on an official Inboxiqo page.

Payment, refunds, and changes

Paid plans, subscriptions, and credits are provided according to the pricing shown at purchase. Unless a separate written agreement says otherwise, fees are non-refundable except where required by law or where Inboxiqo confirms a billing error.

We may update pricing, limits, features, or these terms. Material changes will be posted on the website or communicated through the service.

Suspension and termination

We may suspend or terminate access if we believe an account violates these terms, creates legal or security risk, abuses the service, threatens platform stability, or fails to pay required fees.

After termination, we may delete or retain data according to our Privacy Policy, DPA, legal duties, and legitimate operational needs.

Liability

To the maximum extent permitted by law, Inboxiqo is provided as-is and as-available. We are not liable for indirect, incidental, special, consequential, exemplary, or lost-profit damages arising from use of the service.

Nothing in these terms limits liability where applicable law does not allow such limitation.
