Changelog

MailBolt™ Free Email Verification System

v1.8.0 - 29 Mar 2025

  • Fixed Corrected bug where the email count in a file was not properly calculated, leading to inconsistencies between total emails and emails processed.
  • Fixed Addressed issue where emails were not being properly categorized when uploaded in batches, ensuring accurate categorization based on the selected category.
  • Fixed Fixed export logic to handle large data sets more efficiently, preventing timeouts during email export.
  • Fixed Created new table in the database to track and manage email upload files, including their processing status, total emails, valid emails, invalid emails, and category.

  • New Implemented file upload and processing logic to allow users to upload customized CSV or TXT files with any fields. The files are processed, and emails are categorized into valid, invalid, and duplicate categories, offering greater flexibility for user-defined file formats.
  • New Tracking file processing status within the 'email_files' table, including total emails, valid emails, invalid emails, and processing state (processed or not).
  • New Export functionality added to allow users to export the emails stored in the 'verifications' table, filtered by category, status, and quality score.
  • New Updated subscription handling to reflect the number of emails processed in the 'subscriptions' table, updating the 'emails_used' field after each upload.
  • New Added ability to associate uploaded email files with a specific category for better organization and filtering in the dashboard.
  • New File upload failure handling implemented with improved error messages to notify users if their file could not be uploaded due to size or format issues.

    • v1.7.0 - 25 Mar 2025

  • Fixed Corrected domain typo handling to prevent "gmail.com" from becoming "gmail.comm".

  • New Integrated Gravatar verification to boost the score of emails with an associated profile, improving accuracy without falsely elevating the score of non-existent addresses.
  • New Optimized SMTP verification logic with dynamic connection adjustments based on server load and reattempts, reducing false positives and resource overuse.
  • New Refined offset handling and dashboard synchronization to resume email verification from where it left off, even if the user navigates away or closes the page.
  • New These enhancements are now available exclusively in the Verify Emails Pro system.

    • v1.6.1 - 6 Mar 2025

  • Fixed Resolved an issue where exporting emails with "All Categories" resulted in a blank file. This was caused by an incorrect SQL query condition that unintentionally filtered out all results when no specific category was selected.
  • Fixed Ensured that selecting "All Categories" properly includes all emails in the exported CSV. The system now correctly handles exports by removing category-based filtering when "All Categories" is chosen, ensuring that all stored emails are included regardless of category.
  • Fixed Addressed a filename inconsistency when exporting with a minimum Quality Score, ensuring the filename correctly reflects the applied filters.

  • New Added an option to export only email addresses (without category or score), simplifying data extraction.
  • New The exported file now includes the **minimum Quality Score filter** in its filename when applied (e.g., MailBolt™_All_Categories_All_Emails_MinScore80.csv).
  • New Implemented logging of SQL queries and parameters to assist in debugging export-related issues.
  • New If no matching data is found for export, the system now generates a CSV file with only headers instead of returning a blank page.

    • v1.6 - 5 Mar 2025

  • Fixed Optimized resource usage by caching DNS and security verification results per domain, reducing server load.
  • Fixed Increased overall email verification accuracy to 95-98% by leveraging the new quality scoring and enhanced security checks.

  • New Implemented a Quality Score system (0-100) to evaluate email quality based on domain reputation, security checks, and typo corrections.
  • New Redesigned the Quality Score distribution so that scores now start at 0 and accumulate to 100 as follows:
    • No typo error: +15 points; typo corrected: +5 points.
    • MX records found: +20 points.
    • Security checks (SPF, DMARC, DKIM): +15 points each (maximum +45 points).
    • SMTP simulation: success yields +20 points; timeout yields +10 points.
  • New Emails with a Quality Score below 70 are automatically flagged as invalid.
  • New Added email syntax validation using FILTER_VALIDATE_EMAIL to filter out improperly formatted emails.
  • New Integrated automatic typo correction for common domain errors (e.g., converting gmaill.com to gmail.com) with corresponding score adjustments.
  • New Enhanced SMTP verification to simulate real delivery by sending a RCPT TO command via cURL, allowing detection of actual email acceptance.
  • New Added security verifications by checking for SPF, DMARC, and DKIM DNS records, with score adjustments based on their presence.
  • New Implemented dynamic adjustment of simultaneous cURL connections based on current server load using sys_getloadavg(), optimizing performance under varying load conditions.
  • New These enhancements are now available exclusively in the Verify Emails Pro system.
