To know if a campaign has been sent to entire audience without errors, you should consult these metrics:
- Sent = 100%
- Delivered = 100%
- Bounced = 0%

From bounce window you can download a .csv document, by clicking on button at the top, with data of all customers who have not received campaign. In same file reason for bounce appears to keep track of errors.

Status, deliveries and diagnosis
Distinguish campaign status from each recipient's outcome. A scheduled campaign has not been sent yet; sending does not necessarily mean delivery, opening or a reply. Some outcomes arrive after the initial send.
Before repeating a campaign, review its report, period, channel and affected recipients. A delivery rate below 100% does not, by itself, identify the cause or mean that you should resend to the whole audience.
Investigate an issue
- Find the campaign and check whether it is a draft, scheduled or already sent.
- Review which recipients were included and excluded.
- Check delivery events and the available error details.
- For email, review the address and bounce reason; for WhatsApp, review the number and Twilio template.
- Correct the cause and limit retries to recipients who actually need them.
Respect unsubscribes and exclusions. Do not use a reimport or resend to bypass a request not to receive communications.
Email suppressions
In Settings > Data > Email suppressions, with Data permission, you can view contacts flagged for a bounce, spam report or unsubscribe. A contact can have several restrictions, and the list lets you open their profile.
Remove a restriction only after checking the address, resolving the cause and verifying the contact's consent. Delete beside the reason removes that restriction, not the contact. The action requires confirmation and changes only the selected flag; other restrictions may remain active.
Removing a suppression does not automatically resend a campaign or guarantee that the provider will deliver the next email. Do not use this option to ignore an unsubscribe or complaint.
