Standard email validation results only tell part of the story. Consequently, MailboxValidator has introduced two advanced features to help users make better data-driven choices.
The first feature is the MailboxValidator Score. Meanwhile, the second feature is advanced Catch-All detection.
MailboxValidator Score #
MailboxValidator utilizes a sophisticated algorithm to calculate this reputation score. Essentially, higher scores indicate that an email address has high deliverability. On the other hand, lower scores mean the exact opposite.
The scoring system is divided into three distinct categories:
- Good: Scores above 0.70.
- Fair: Scores between 0.40 and 0.70.
- Poor: Scores at or below 0.40.
In contrast to a simple “valid or invalid” status, this granular data offers deep insight. Therefore, you can easily customize your own deliverability thresholds.
Marketers who practice excellent email hygiene like double opt-in should focus strictly on high scores. Indeed, any fair or poor scores on a clean list are likely outliers. Thus, you should treat them as invalid.
Conversely, users with older or unverified lists might see mostly lower scores. In this scenario, you must decide how much risk you want to accept. Including lower scores may boost reach, but it dramatically increases your bounce risks.
Catch-All Detection #
A catch-all email domain accepts all incoming messages, regardless of the specific recipient name. However, your emails can still easily bounce depending on the final server configuration. Furthermore, if the specific mailbox does not exist, your email might go straight to the trash.
Consequently, sending to catch-all addresses often wastes your marketing budget. After all, bulk email sending providers charge you for every single attempt. Therefore, it is best to remove catch-all emails unless you are certain a real person owns the address.
Conclusion #
Static email verification is no longer enough in today’s competitive environment. Instead, modern marketers need deeper email intelligence. By leveraging these advanced metrics, you can confidently protect your sender reputation and maximize your ROI.
