In their own words
Bulk Email Checker
Bulk Email Checker checks whether email addresses appear valid, using bulk uploads or checks through a real-time API. Its bulk workflow accepts CSV and tab-delimited files, removes duplicates, checks syntax, DNS/MX records and mailbox status, and supports CSV and Excel output. The maker describes a verification process with more than 17 factors, including RFC validation and deep SMTP checks. Additional checks can identify disposable or role-based addresses, catch-all servers, possible typos and spam traps, and enrich results with MX server information. The RESTful JSON API can check addresses at signup, checkout or CRM entry, with support for Python, PHP, Node.js and other major stacks. Integrations listed include blacklist synchronization with MailChimp, SendGrid, Mailgun, Postmark and Mailjet, plus Google Sheets, Excel and WordPress. Ten checks are available without signup, and a free plan and trial are listed. Paid options start at $9.95, paid once purchase for 10,000 verifications; monthly unlimited API plans vary by concurrent threads. The service is available on web, Linux, macOS and Windows, as well as through its API.
DeBounce
DeBounce checks email addresses for syntax, domain, mailbox, catch-all and other issues. Users can upload TXT or CSV lists for bulk validation, then download result segments they can customize. The service detects disposable addresses and filters spam traps and honeypots. Its API handles real-time and bulk checks and can be used from Shell, Node.js, Ruby, PHP and Python environments. Concurrent validation defaults to five requests; higher throughput may be available on enterprise plans. List Monitoring rechecks connected lists about daily, typically 15–35 times per month, and usually uses credits equal to around twice the monitored list size each month. Integrations include HubSpot, Google Sheets, Mailchimp, ActiveCampaign, Mailjet, ConvertKit, MailerLite, Klaviyo, Brevo, Mailgun, WordPress and Zapier. DeBounce says real-time API addresses are not stored and bulk lists and result files are deleted after seven days. Its Pay-As-You-Go option is listed at free, with 5K–5M credit options, one credit per email validation and credits that never expire. A free plan and free trial are listed.
