Tracking delivery — sent, delivered, failed
Last updated 2 min read
In Email Studio → History, each blast shows a status pill and counts:
- Sent — everything was handed off successfully.
- Partial — some recipients succeeded, some failed; open the blast to see failure details (for team blasts, the most common reason is a team with no valid email address).
- Failed — nothing could be sent.
Donor-style blasts (queued sends) show Total, Sent, and Failed tiles, and a live progress bar while sending is still in flight. "Sent" for email means the recipient's mail provider accepted the message — where it lands (inbox, promotions, spam) is up to that provider; see Why an email may not arrive.
SMS
SMS Center → History lists every blast with a status pill: Queued, Sending, Sent, Partial, Failed, Scheduled, or Cancelled. The list refreshes itself while a blast is running.
Click a blast to open Message Details, the most granular view in the hub:
- A stacked progress bar and four tiles: Total, Delivered, Sent/Pending, Failed.
- A per-recipient list where each person carries their own status: Pending, Sent, Delivered, Failed, Undelivered, or DNC blocked — with the error reason shown for failures.
The distinction between Sent and Delivered matters: Sent means we dispatched the message to the carrier network; Delivered means the recipient's carrier confirmed it reached the handset. Delivery confirmations arrive asynchronously, so expect counts to keep climbing for several minutes after a blast finishes sending. Some carriers never send confirmations at all, so a small permanent "Sent" remainder is normal.
Tip: A recipient showing Undelivered repeatedly across blasts usually means a disconnected or landline number — worth cleaning from your list.
Voice broadcasts
While a broadcast runs, the Robocalls progress panel updates live with per-call outcomes:
- Completed — a human answered and heard the message.
- Machine — an answering machine or voicemail was detected.
- No Answer / Busy — the phone rang out or was engaged.
- Failed — the call couldn't connect (bad number, network error).
- DNC Scrubbed — skipped because the number is on your Do Not Call list.
- Skipped — removed during validation (invalid number). Duplicate numbers are dropped before dialing begins and reported as a duplicate count at launch, so they don't appear here.
Finished broadcasts move to Broadcast History, where you can revisit the same breakdown plus per-call logs — including who pressed 7 to opt out.
Reading the numbers honestly
A 100% delivery rate doesn't exist in the real world. Healthy campaigns typically see a small percentage of failures from disconnected numbers and dead mailboxes — what matters is the trend. If a particular blast shows a spike in failures compared to your usual baseline, check the error reasons in the detail view, and see Troubleshooting failed sends before your next attempt.
