Broadcast shows as Partial or Cancelled

A broadcast you sent shows a Partial or Cancelled status instead of Sent, and you need to understand what happened and whether any members didn’t receive it.

What’s happening

Partial — the broadcast started dispatching but stopped before all emails went out. This happens when a broadcast is cancelled while it’s in the Sending state, or when a send fails part-way through — it ends as Partial rather than staying on Sending.
Cancelled — an admin cancelled the broadcast. If it was cancelled from the Queued state (before sending started), no emails were dispatched. If it was cancelled during sending, some emails may have already been dispatched.

How to fix it

1. Find out how many emails dispatched

Go to All blasts (at /admin/email/broadcasts) and open the broadcast.
On the send-detail page, check the progress counter — for example, “743 of 1,000 dispatched.” This tells you how far the send got before it stopped.
Filter the Recipients table by Bounced, Delivered, and Pending to see which members received the email, and filter by Suppressed to see who was excluded.

2. Resend to the members who missed it

If some members didn’t get the email, you can send it again to just those members.

On the broadcast’s send-detail page, select Resend to missed recipients only. This button appears on a Sent or Partial broadcast when some members were missed.
The dialog reads “This sends only to recipients we couldn’t reach on the first send — up to {N}. Anyone who has opted out since won’t get it.” Optionally add a reason, then select Resend to up to {N}.

“Missed” means members of the original send’s audience — as it was when that send started — whom the email provider never received the email for. That includes members a sending-capacity limit held back, and members a send that failed part-way never got to. It doesn’t include:

members whose email bounced or who marked it as spam — those emails reached the provider, so they’re never sent again;
members who joined the segment after the original send — the resend doesn’t look up the segment again;
members an earlier resend of this broadcast skipped because they had opted out since, and members an earlier resend is still sending to (it’s Queued or Sending and has moved in the last 15 minutes);
members the send can no longer reach — for example, they no longer have an email address or have been deleted. Members whose data has been erased, and archived members, aren’t missed either — a resend skips them.

Resends of the same broadcast — including a resend of a resend — run one after the other, and each sends only to whoever the earlier ones didn’t cover.

Members who already received the email don’t get it twice. When you confirm, “Resend queued — up to {N} recipients” appears and the new send’s detail page opens. The number is an upper bound: anyone who has opted out since is dropped when the resend sends.

If the button is greyed out:

“All recipients received this — nothing to resend” — everyone the broadcast could reach got it.
“No one could be sent this broadcast — no one in its audience could be reached. Nothing to resend.” — the original send had nobody to reach (for example, its audience matched no one, or everyone in it had opted out or has no email address).

3. If the broadcast was cancelled by mistake

If it was cancelled while Sending and shows Partial, use Resend to missed recipients only as described above.
If it was cancelled before sending started (Cancelled, nothing dispatched), it can’t be resent. Compose a new broadcast — you can use the cancelled broadcast’s send-detail page to recreate the subject, body, and audience.

If that didn’t work

A resend has stayed on Queued or Sending for more than 15 minutes without moving — that resend lost its send, and nothing retries it automatically yet. Its members count as missed again, so go back to the original broadcast and select Resend to missed recipients only again.
“Nothing left to resend” — by the time you confirmed, everyone in the original audience had been reached, so no new send was created.
“Resend to missed recipients only” isn’t shown — your role may not include permission to send broadcasts, or the broadcast hit your sending capacity (resending would reach the same limit — see Email reached sending capacity).
“This broadcast can’t be resent” — only sent or partial broadcasts can be resent.
If the broadcast shows Partial and you didn’t cancel it, the send ended part-way for one of two reasons: it reached your sending capacity (see Email reached sending capacity), or MapleGather’s email provider didn’t accept some of its messages (a rejected address, or a provider error at the time). The members it didn’t reach count as missed, so you can use Resend to missed recipients only. If the same members are missed again, the provider is refusing their messages — check those members’ email addresses.
