Find and fix messages that didn’t send

Sometimes WhatsApp refuses a message: the 24-hour window closed, the number isn’t on WhatsApp, Meta blocked it. Exabloom shows you which messages failed, why, and whether sending again will help.

What happens when a message fails

When WhatsApp won’t deliver a message, two things happen. The message turns red in the chat, with the reason written underneath. And it joins the Failed Messages list, one place for every failure in your workspace, whoever or whatever sent it: a teammate, a bulk send or a workflow.

Reminder: your trial class is tomorrow…

3It joins one listEvery failure in the workspace, until someone dismisses it.
One failed reminder, start to finish, in order.

Your routine is simple: open the list, read each reason, fix what can be fixed, and dismiss the rest. The reason is the important part. It tells you whether sending again will work, or whether the message was never going to arrive.

Everyday

Open the Failed Messages list

The list lives inside the Inbox. It doesn’t have a sidebar item of its own: you open it from a red banner that only appears when something has failed.

① Inbox, at the top of the left sidebar. ② The red banner at the top of your chat list says how many messages failed; click View all. ③ With no chat open, the same shortcut also sits in the middle of the screen.
No banner?
Then nothing has failed in the last 48 hours. If the banner is grey and says “1 failure dismissed · Review”, everything has been dealt with, and Review opens the dismissed ones. Closing the banner with × only hides it until the next failure.

Work through the list

The list replaces the chat on the right. Your chat list stays on the left, so you can jump back at any time with the arrow at the top.

① Narrow the list by time, source or reason. ② Open goes to that contact’s chat. ③ The × dismisses a failure you’ve dealt with. ④ Show dismissed brings back what you, or a teammate, cleared.
  • Filter - the time range goes from Last 2 hours to Last 7 days (it starts on Last 48 hours). Source is Workflow, Bulk Send or Manual. Error type narrows to one reason. A Clear link resets them.
  • Open closes the list and opens that contact’s chat. Scroll to the red message to read the full reason.
  • Dismiss (×) moves the failure off the active list. It doesn’t delete or resend the message. It only says “handled”.

Changed your mind? Show dismissed switches the list to what’s been cleared, and Restore puts one back.

DKDaniel KohHi Daniel, your invoice for June is attached. Restore
The dismissed view. Restore moves a failure back to the active list. Hide dismissed returns to it.
Dismiss is for the whole team
Dismissing clears the failure for everyone in the workspace, not only for you. Agree who works the list, so a teammate doesn’t dismiss something you were about to fix.

Read the reason in the chat

The list only has room for a short label, and several different problems share the label Send failed. The chat has the full story, so open it before you decide what to do.

Siti’s reminder, opened from the list. ① The failed message, in red. ② This one needs a template, so the fix is right there in the reply box.

Every failed message on a WhatsApp Business number reads the same way:

  1. 1The reason, in red - plus WhatsApp’s error code on the right.
  2. 2Your message, dimmed - kept so you can see exactly what didn’t go.
  3. 3What it means - and who caused it: WhatsApp, Meta, the contact or us.
  4. 4When, and on which number - the Failed tag is at the end.
The same failed message, full size. The numbers match the four parts.
On other channels
Failed messages on Messenger, Instagram, Telegram and a regular WhatsApp number don’t get the red card. They show a small red retry arrow next to the time instead (see Send it again).
Reference

What each reason means

The title is what the red card in the chat says. “In the list” is the shorter label on the Failed Messages list. The tag says whether sending again will help.

24-hour window expired
In the list: Send failed
Won’t help
The contact hasn’t written to you in more than 24 hours, so WhatsApp only accepts approved templates. Send a template message instead.
Message couldn't be delivered
In the list: Send failed
Try later
The contact couldn’t be reached: poor signal, WhatsApp deactivated, or a temporary block. WhatsApp doesn’t say which. Try again later. If it keeps failing, call or email them.
Recipient not on WhatsApp
In the list: Not on WhatsApp
Won’t help
This number isn’t registered on WhatsApp. Check the number on the contact, or reach them another way.
Quality-related block
In the list: Blocked by WhatsApp
Won’t help
Meta has temporarily limited messages to this person to protect them. It’s Meta’s decision, not ours. The red card has a Learn more link to Meta’s explanation. Wait for them to message you first. Don’t keep retrying.
Recipient on Do Not Disturb
In the list: Do Not Disturb enabled
Won’t help
The contact has Do Not Disturb switched on. Respect it. Only lift DND on the contact if they asked you to.
Payment issue
In the list: Payment issue
Try later
Your WhatsApp Business account has a billing problem with Meta. Fix the payment method in Meta Business Manager, then send again.
Account temporarily restricted
In the list: Send failed
Won’t help
Meta has restricted your WhatsApp Business account for a policy issue. Contact us. Nothing will send until Meta lifts it.
Network timeout
In the list: Network timeout
Send again
We couldn’t reach WhatsApp because of a network issue on our side. Send it again.
No response from WhatsApp
In the list: Message timed out
Send again
WhatsApp never confirmed it received the message. It may or may not have arrived. Check with the contact, then send again if needed.
Couldn't deliver after retries
In the list: Max retries exceeded
Try later
We already retried automatically and WhatsApp still couldn’t deliver it. Try again later. If it persists, contact us.

Send it again

On a WhatsApp Business number there is no Retry button. Once you’ve fixed the cause, open the chat and send a new message, or a template if the 24-hour window has closed. Copy the wording from the dimmed original in the red card.

On other channels, a small red retry arrow sits next to the failed message’s time (“Retry sending message”). Click it to send the same message again.

Don’t retry into a block
A Quality-related block means Meta is protecting this person from your number. Sending again can make the block last longer and hurts your number’s quality rating. Wait for them to message you.
Before you go

Good to know & pitfalls

  • Some failures fix themselves. When WhatsApp is busy, Exabloom retries once on its own. You only see the failure if that retry also fails (Couldn’t deliver after retries).
  • The list covers the last 7 days. Older failures drop off, even if nobody dismissed them.
  • Open lands at the bottom of the chat, not on the failed message. Scroll up to find the red card if more messages came after it.
  • “Media download failed” is about a file they sent you. It means a photo or document the contact sent couldn’t be downloaded, not that your message failed. Ask them to send it again.
  • A disconnected number fails everything at once. On a regular WhatsApp number, messages that couldn’t go out because the phone was disconnected are listed as WhatsApp disconnected. On a WhatsApp Business number they show up as Send failed, and the red card may only say “Something went wrong”. Either way, if several failures land at once, check Settings → Social Channels and reconnect before sending anything again.
  • The banner and the list can count dismissals differently. The banner counts the last 48 hours; Show dismissed counts 7 days. Neither is wrong, they just look back different distances.
