What It Is

EmailRep.io is a reputation and risk lookup API for email addresses. It helps answer questions such as “Is this email suspicious?”, “Is it a disposable account?”, “Does it have a credible internet presence?”, and “Can the sender be trusted?” It returns fields such as reputation, suspicious, references, and detailed risk indicators. It is not positioned as a full email gateway, but as an email intelligence supplement for security, risk control, registration, and marketing systems.

Core Capabilities

In terms of protection signals, it covers email blacklists, malicious activity, recent malicious activity, credential leaks, data breaches, spam, disposable email, free email, deliverability, MX, SPF, DMARC, spoofability, domain reputation, new domains, suspicious TLDs, and more. It can also return profiles, helping users understand an email address’s public footprint on the internet. Deployment is primarily via API, with curl query examples provided in the documentation, making it suitable for integration into registration flows, MFA triggers, anti-fraud systems, email security analysis, or sales lead validation.

Pricing and Support

Pricing is transparent: Community is free, with 250 queries per month and up to 10 per day; Commercial costs $20/month, with 1000 queries per month and no daily limit, plus email support; Enterprise is custom-priced for high-volume or high-throughput use cases and includes SLA support. Payment methods are not disclosed in the main text, and details on compliance certifications, data sources, update frequency, and privacy handling are also not specified.

Pros and Cons

The advantages are simple integration, intuitive fields, a free tier that is convenient for testing, and a relatively low-cost commercial plan, making it useful as an email reputation feature in risk-control workflows. The limitations are that it only provides email context and cannot replace comprehensive inspection of email content, attachments, URLs, and headers. The official documentation also notes that even high-reputation senders may still be compromised or spoofed. In addition, the main text does not show capabilities such as an admin console, alerts, reporting, or bulk operations.

Who It’s For and Access from China

It is suitable for security analysts, email security researchers, anti-fraud teams, registration risk-control teams, and marketing or sales teams that need to verify real email addresses and protect sender reputation. Access from China is not covered in the main text, so network connectivity and payment availability should be verified through actual testing. If access is limited, alternatives may include domestic email security gateways, anti-fraud services, or self-built email reputation rules.
