Reputation and Inbox Placement Rate:
As this chart from Return Path shows, sender IPs with low Sender Scores are rejected by the ISPs. It is only at the very highest Sender Score reputation levels that email is routinely “accepted” into the Inbox.
| Unknown User Rate | Sender Score | Accepted Rate | |
| 9.10% | 40-49 | 6.70% | |
| 7.30% | 50-59 | 26.80% | |
| 5.50% | 60-69 | 58.00% | |
| 1.60% | 70-79 | 88.20% | |
| 0.90% | 80-89 | 93.60% | |
| 0.20% | 90-100 | 99.40% | |
Average Inbox Placement Rate with a Sender Score of 91 or greater is 88%
This is much lower than the 99% “accepted” rate that many ESPs tout. Note the difference between Inbox Placement Rate for the lowest reputation senders and the highest – IPs with a Sender Score of 100 are 38% more likely to get into the Inbox than those with a Sender Score of 50.

Pre-Send Email Validation:
Send us a list of addresses to identify and remove invalid emails from your database before you mail! Most hygiene vendors will accept as valid any email address that is properly formatted, comes from a domain configured to receive mail and does not appear in one of their suppression lists–even if that email address does not correspond to an existing mailbox.
In contrast, LeadSpend actively verifies email addresses to determine if the account is valid and deliverable at that specific moment in time. This allows us to correctly verify over 97% of consumer email addresses. We do not keep any consumer information in a database, ensuring maximum security and accuracy.
