From detection to governance

AntiTemp ships three pillars—Detect, Operate, Govern—so Product, Growth, and Risk teams stay in lockstep.

Explainable Risk Engine

Product Pillar

Multi-signal scoring upgrades old-school blacklists. Every check includes a score (0-100), triggered signals, narrative context, and an action recommendation.

  • 6+ live detectors: DNS, domain age, alias patterns, external intel
  • Safe / Suspicious / Danger thresholds map to product policies
  • Evidence snippets make support handoffs painless
Benchmarked at ≥95% precision across 2.3M real checks (2024).

Unified Operations & ESP Automations

Product Pillar

Run real-time checks for signups and multi-email clean-ups for marketing in the same place. Credit deductions, progress tracking, and refund logic are fully automated.

  • 50 emails per API call with aggregated results
  • Connect ESP/CDP tools (Mailchimp, HubSpot, Klaviyo) or upload CSV/XLSX
  • Schedule weekly hygiene jobs and sync results back automatically
Protects acquisition spend while keeping deliverability north of +15%.

Governance & Appeals Hub

Product Pillar

Mistakes happen. AntiTemp bakes in appeals, allow/deny lists, and audit trails so Risk teams can overrule machines without losing traceability.

  • Appeals queue with SLAs and status tracking (<24h target)
  • Team-managed whitelists/blacklists, tied to rules + provenance
  • Immutable audit log showing who changed what and why
Closes the loop so compliance, CS, and fraud ops stay aligned.

Deliverables you can ship today

Data reports, dashboards, and governance exports match what customers ask for during onboarding audits and pilot rollouts.

Risk & hygiene reports

CSV/PDF exports summarizing total checks, risk-level distribution, and recommended actions—ready for weekly deliverability reviews.

  • Multiple email check summaries
  • Trend charts ready for exec reviews
  • Per-email evidence trail

Live dashboards

Homepage tiles, history charts, and data-dissolve widgets help teams monitor KPIs like detection accuracy and deliverability.

  • Home indicators
  • Historical throughput
  • Health ratios for each segment

Governance artifacts

Appeal tickets, whitelist approvals, and audit logs export cleanly for compliance or downstream BI systems.

  • Role-aware approvals
  • Full change log w/ actor + reason
  • Webhook-friendly JSON

Built for every stakeholder

One narrative keeps Growth, Risk, and Engineering aligned on the same system and KPIs.

Marketing & Lifecycle

Boost deliverability before you spend

Lists quietly rot when throwaway emails sneak into ESPs, tanking open rates and wasting campaign budget.

Upload CSVs or connect Mailchimp/HubSpot → Auto-detect email column
Run hygiene job (100K rows max) with custom thresholds
Push clean segments back to the ESP/CDP and track ROI
Typical senders recover +15-20% deliverability after two hygiene cycles.

Risk & Compliance

Explainable decisions and fast appeals

Security teams need to stop abuse without stonewalling legit users—and auditors want the receipts.

Review flagged addresses with signal evidence + recommendations
Handle appeals in a shared queue with <24h SLA
Amend allow/deny lists and export immutable audit logs
Governance workflows cut false-positive escalations by ~50% in pilot teams.

Builders & Platform Teams

Embed AntiTemp anywhere in minutes

Developers juggle brittle validation scripts and inconsistent responses from legacy services.

Call `POST /api/v1/email/check` (1 credit per call, cached or not)
Consume typed success/error envelopes with shared `meta` telemetry
Pipe decision + evidence into signup flows, support tooling, or LLM automations
Versioned envelopes, request IDs, and rate-limit headers cut integration churn to near zero.

"The API response time is insane - consistently under 300ms. The Multiple Email Check endpoint saves us hours of manual work. Support team actually responds too, which is rare these days."

"Finally a solution that explains WHY an email is risky. We had so many complaints about false positives with our old blacklist. AntiTemp's multi-signal approach is way more accurate."

"The appeal system is brilliant. When we had a false positive, our customer could submit proof and get whitelisted. Builds so much trust compared to just blocking them."

Frequently Asked Questions

Everything you need to know about AntiTemp

We analyze 6+ signals including domain reputation, MX records, domain age, pattern matching, and blacklist/whitelist databases. Emails are scored 0-100, where higher scores indicate higher risk. Temporary/disposable email services, suspicious patterns, invalid DNS records, and newly registered domains all contribute to risk scores.
Our multi-signal AI achieves 95%+ accuracy in identifying disposable emails. Unlike simple blacklist solutions that rely on static lists, our system combines multiple detection methods and continuously learns from new patterns. We also provide detailed explanations for each score, so you can understand exactly why an email was flagged.
We've built an appeal system specifically for this. Users can submit appeals with supporting documentation (like domain registration proof), and you can review and approve them through your dashboard. Approved domains are added to your custom whitelist, ensuring they won't be flagged again. This governance system significantly reduces false positives over time.
Our API typically responds in under 500ms for real-time checks. For multiple emails, use the Multiple Email Check API to send up to 50 addresses in one call and get results instantly.
We offer a 1,000 credit free trial so you can test the service risk-free. If a multi-email request fails, unused credits are automatically refunded. If you're not satisfied with the service, contact our support team within 7 days of purchase and we'll work with you to find a solution.
Integration is simple via our REST API. Just make a POST request to /api/v1/email/check with the email address. You'll receive a JSON response with the risk score, level, and detailed signal breakdown. We provide code examples for JavaScript, Python, PHP, and other popular languages in our documentation.
Real-time processing is for checking individual emails during user registration or form submission. Multi-email checks let you send up to 50 addresses in a single API call for quick list cleanups without file uploads. Both use the same detection engine and provide the same detailed analysis.
Absolutely. We're GDPR compliant and take data security seriously. Email addresses are encrypted in transit and at rest. We don't share or sell your data to third parties, and multi-email payloads are discarded immediately after processing. You can review our full privacy policy and security practices in our documentation.
