What are the main differences between StopBouncing and Debounce?
Both provide SMTP-level email verification with bulk and API options. StopBouncing differentiates on EU hosting and GDPR compliance, non-expiring credits, and a clean pay-as-you-go pricing model with no subscription required. If these factors matter for your use case, StopBouncing is worth evaluating.
Can I migrate my existing integration from Debounce to StopBouncing?
API integrations require updating your endpoint URLs, authentication headers, and response parsing since the APIs have different schemas. Bulk CSV upload workflows can be migrated immediately with no code changes — just upload your list to the StopBouncing dashboard.
