If you’re experiencing issues with receiving proof or approval emails, start by checking this documentation on proof issues.

Live proofs have a timeout limit of 5 minutes. When targeting expressions include large recipient pools or complex criteria, delivery delays can occur, or proofs may not be sent at all. To optimize delivery:

• Use more specific targeting expressions: Narrow down your criteria, for example, by using “random 50” rather than broad targeting terms.
• Simplify targeting conditions: Avoid intricate or layered expressions. Keeping conditions straightforward reduces processing load, helping proofs reach you faster.
• Limit data volume: Smaller, simpler recipient pools help prevent timeouts.

Why am I receiving fewer than five live proofs?

Live proofs select five random subscriber profiles from the activity’s target expression. However, each selected profile must also satisfy the activity’s partition restrictions.

If some selected profiles do not belong to the required partition—or have no partition assigned—those proofs cannot be generated or delivered. As a result, you may receive fewer than five live proofs even when the activity log shows that five samples were selected.

To avoid this:

• Ensure the target expression only includes subscribers from the relevant partition.
• Confirm that eligible subscribers have the correct partition assigned.
• Compare the target estimate with the final partition-filtered audience.

If only a small portion of the estimated audience matches the partition, there is a greater chance that some randomly selected live-proof profiles will be ineligible.
