In their own words
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.
EmailMarker
EmailMarker verifies individual email addresses and lists to help remove invalid entries, reduce bounces, and protect sender reputation. Its checks cover syntax and typos, disposable and role-based addresses, spam traps, MX records, catch-all settings, SMTP, domain age, and a risk score. For bulk work, users can upload CSV files, review valid, invalid, risky, and unknown results, and download cleaned lists; uploads can contain up to 1 million emails. The REST JSON API supports single and bulk verification with API-key authentication, and code examples or SDKs are listed for Node.js, Python, PHP, Ruby, and Go. Integrations include Mailchimp, GetResponse, Kit, AWeber, ActiveCampaign, Klaviyo, Brevo, MailerLite, SendGrid, and Mailgun. EmailMarker is available on the web and through an API, and offers real-time form checks. The free signup includes 150 verifications at free. Paid credits are one-time purchases, starting at $3, paid once for 1,000 verifications. Results may vary and are not guaranteed to be absolutely accurate.
