Features and specs

What each product offers, as listed by its team.

Proofy 9 features
Deadpendency 5 features
  • Multi-Layer Email Verification
    Proofy checks syntax, domain and DNS validity, MX records, SMTP and mailbox signals, disposable addresses, catch-all domains, role-based emails, and additional risk indicators.
  • Bulk Email Verification
    Upload CSV or TXT files to verify large email lists in bulk, preserve original data, and export cleaned or segmented results by verification status.
  • REST API Verification
    Integrate real-time email verification into signup forms, CRMs, applications, lead-generation systems, and backend workflows through the REST API.
  • Verification Statuses
    Emails are classified as Valid, Invalid, Risky, or Unknown to help users understand list quality and make better sending decisions.
  • Disposable & Catch-All Detection
    Identify disposable email addresses, catch-all domains, and other risky address types that can reduce list quality and campaign performance.
  • Role-Based Email Detection
    Detect role-based addresses such as info@, sales@, support@, and similar shared mailboxes during the verification process.
  • Domain, MX & Mailbox Checks
    Validate domain configuration, MX records, mail-server availability, mailbox-level signals, and other infrastructure indicators without sending an email.
  • High-Volume Processing
    Proofy is designed for high-volume email verification workflows, supporting large bulk files and scalable API-based processing for business use cases.
  • Flexible Pricing
    Choose pay-as-you-go or subscription pricing. Verification credits do not expire, duplicate addresses are not charged, and Unknown results are not charged.
  • Automated Dependency Monitoring
    Deadpendency automatically checks your project's dependencies for signs of being dead, unmaintained, or deprecated, saving developers from manually tracking the health of each dependency.
  • GitHub Integration
    Deadpendency integrates directly with GitHub as a GitHub App, making it easy to set up and run as part of your existing pull request and CI workflow without requiring additional infrastructure.
  • Early Warning System
    By catching dead or unmaintained dependencies early, Deadpendency helps teams avoid security risks and technical debt that come from relying on abandoned libraries.
  • Multi-Language Support
    Deadpendency supports a wide range of programming languages and package ecosystems, making it useful for polyglot projects and diverse development teams.
  • Low Configuration Overhead
    The tool is designed to work out of the box with minimal configuration, allowing teams to get value quickly without spending significant time on setup and customization.

Possible disadvantages

  • Limited to GitHub
    Deadpendency is primarily a GitHub App, which means teams using other platforms like GitLab or Bitbucket cannot easily use the service without switching or mirroring their repositories.
  • Potential False Positives
    The tool may flag dependencies as dead or unmaintained based on activity metrics, even when a library is stable and simply mature, leading to unnecessary concern or migration efforts.
  • Niche Use Case
    Dependency health checking is a relatively narrow function. Teams may prefer more comprehensive dependency management tools that also handle vulnerability scanning, license compliance, and version updates in one solution.
  • Reliance on External Signals
    Deadpendency relies on external signals like repository activity and release frequency to determine dependency health, which may not always accurately reflect the true maintenance status of a project.
  • Limited Community and Ecosystem
    As a relatively niche tool, Deadpendency has a smaller user community compared to alternatives like Dependabot or Renovate, which can mean fewer resources, community support, and third-party integrations.

  • Simple integration as a GitHub Action, making it easy to add to existing CI/CD pipelines without heavy configuration
  • Provides clear, actionable reports that help developers proactively address technical debt before it becomes a security or maintenance liability
  • Supports multiple language ecosystems, offering broad applicability across different tech stacks
  • Lightweight and automated approach reduces manual auditing effort for dependency health
