Updated 2026-07-24For: Agents · Supervisors
Allowed file types and sizes depend on both the channel and workspace limits. Email and API channels expose additional delivery state.
Steps
Attach a file
Choose a file in the reply composer and wait for the upload to complete before sending.
Confirm the recipient
For sensitive content, verify the customer and conversation before delivery.
Handle failure
If delivery fails, review the reason. Correct the address, file, or channel state before retrying; do not send repeated duplicates.
