DeBounce

What DeBounce is

DeBounce verifies email addresses with syntax, domain, mailbox, catch-all, and other checks. It supports bulk validation through TXT or CSV uploads, then lets users download customized result segments. The service detects disposable addresses and filters spam-trap and honeypot emails. 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 approximately once a day, usually 15–35 times each month, and typically uses credits equal to about twice the monitored list size per month. Integrations include HubSpot, Google Sheets, Mailchimp, WordPress, Zapier, and others. DeBounce says real-time API addresses are not stored, while bulk lists and result files are automatically deleted after seven days. It states that retained personal data is stored in Germany and that it is GDPR compliant. DeBounce offers a free plan and a Pay-As-You-Go plan at no cost, with 5K–5M credit options, one credit per email, and credits that never expire.

Who it suits

DeBounce suits people who need to validate individual addresses through an API or process email lists in bulk. It may also suit teams connecting validation or list monitoring to the listed marketing and productivity tools.

Limits

The free plan's quotas are not described in these facts. Pay-As-You-Go credit options range from 5K to 5M, with one credit used per email validation; credits do not expire. List Monitoring typically consumes about twice the monitored list size in credits each month, and API concurrency defaults to five requests.

Getting started

1. Visit the DeBounce website.

3. Upload a TXT or CSV list for bulk validation, or use the API for real-time or bulk checks.

Verdict

DeBounce covers bulk and real-time email checks, with integrations and list monitoring for ongoing validation. Its free plan and Pay-As-You-Go option are available, but users planning API concurrency or monitoring should account for the stated limits and credit use.
