When you add contacts to a sequence through the Contacts page you are automatically sent to the Report tab related to this sequence.
This tab sums up all contacts adding to a sequence, including successful ones and failed ones, and the explaination of failures.
This information is available while clicking on each line to a contacts add to the sequence (1) and on the sender (2).
Several reasons can explain failures :
- a contact previously engaged in a former sequence (if in the Settings of this sequence you did not allow contacts that were previously engaged in another sequence to be added to this one)
- missing variables
- unsubscribed contacts
