| Integrations | The maker describes integration through a REST API but does not name third-party app integrations on the opened pages. | Verifalia states that it supports over 6,000 integrations and is officially integrated with Zapier and Pipedream. |
| Security | The privacy policy says data is encrypted in transit and at rest, access is role-based and audit logged, and API keys are hashed. | Verifalia says email addresses are held in RAM rather than persistently stored and that its website and API support TLS 1.3. |
| Support | Enterprise customers can request dedicated support, and the API documentation says customers can contact InboxTrue about higher rate limits. | The pricing page lists regular support for Free, Starter, and Professional, priority support for Enterprise and Ultimate, and free support contact and online chat. |
| Validation checks | The service checks syntax, DNS/MX, SMTP mailbox existence, disposable addresses, and catch-all domains. | Its checks include syntax, domain/DNS/MX, mailbox confirmation, catch-all, role account, disposable email, spam trap, and free email detection. |
