Everything you need
Detect typos, validate deliverability, and block disposable addresses. Clean your lists before you hit send.
Typo Detection
Catch the typos that quietly destroy your deliverability. Every domain is checked against a Levenshtein distance algorithm so common transpositions and missing letters get fixed before you ever hit send.
- Levenshtein distance scoring
- Automatic suggestion of the closest valid domain
- Custom domain allow-list support
MX Record Validation
Don't guess whether a domain can receive mail — verify it. We perform real-time DNS MX lookups with aggressive caching so deliverability is confirmed in milliseconds, not seconds.
- Real-time DNS MX record lookups
- Multi-level cache for repeat checks
- Priority-weighted server validation
Disposable Detection
Throwaway addresses inflate your list and tank your engagement metrics. We cross-reference every address against a curated database of more than 100,000 disposable domains, updated continuously.
- 100k+ curated disposable domains
- Regularly updated blocklist
- Custom domain overrides
Role-Based Filtering
Generic role-based addresses like admin@ or support@ rarely belong to a real person and consistently underperform. We flag them so you can segment them out of your campaigns.
- Detects admin, support, info, sales and more
- Configurable role prefix list
- Segment instead of hard-delete
ESP Integrations
Stop exporting and re-importing CSVs between tools. Inbox Banana syncs directly with the most popular email service providers, so cleaned lists flow back to where you actually send from.
- Two-way sync with 6 major ESPs
- Securely stored, encrypted API keys
- Scheduled, recurring list refreshes

- AES-256-GCM encryption at rest
- SHA-256 hashing for safe lookups
