Sender Reputation Index

The SRI reflects the reliability and trustworthiness of email marketers.
ESPs can resort to the SRI in order to gain additional information about the reputation of existing or potential clients, thereby enabling ESPs to mitigate potential damages to their own reputation at an early stage. Our unique consideration and investigation of individual complaints provides a unique and very useful source of information for our customers.
The index is computed based on data gathered over the last twelve months and may be used to evaluate behavior or compare behavior between senders.
SRI requests can be inquired by any CSA customer via the CLIP customer portal.
Price for one request: 100€ excl. VAT
