RSI’s Email List Cleaning Process:
- Connecting Your Account RSI will connect your patient database to our system and export all patient email addresses. These email addresses will be submitted to Never Bounce for thorough verification and cleaning.
- The Cleaning Process Never Bounce employs a comprehensive, proprietary 20+ step verification process. Each email address is checked up to 75 times from multiple locations globally using a variety of technologies, including MX, DNS, SMTP, social, and private verification methods. This ensures the highest level of accuracy in determining the validity of each email address.
- Cleaning Results After the cleaning process, you will receive a report categorizing the email addresses into the following statuses:
| Result Category | Meaning | Safe to Send? |
| Valid | The server provided a trustworthy response confirming the email is real and deliverable | Yes |
| Accept-All (Unverifiable) | The domain has heightened security settings, making it impossible to determine if the email is valid or invalid | Maybe (risk involved; delivery not guaranteed) |
| Invalid | The server responded, verifying the email as not valid | No |
| Disposable | A temporary email address that will expire after a short period | No |
| Unknown | The server could not be reached | No |
