When someone blocks you, voice messages you send will not reach them
If you send a voice message to someone who has blocked you, the message will sit in your app as if it sent normally — but the other person will never receive it. You typically won't get a notification that you've been blocked. Instead, you'll only notice when messages stop being read, or when you try to call and get an unusual response like a busy signal or no ring at all.
The exact experience depends on which app you're using. On iMessage, a blocked voice message may show as "delivered" on your end even though it never arrived. On WhatsApp, your message will have a single checkmark (sent) but never progress to the double checkmark (delivered). On other platforms like Telegram or Signal, the behavior varies — some show no indication at all that anything went wrong.
The person who blocked you can still see your old messages in their chat history, but they won't receive anything new from you. If they unblock you later, the messages you sent while blocked will not suddenly appear.
Key Takeaways
- Voice messages sent to someone who has blocked you will not be delivered, though your app may show them as sent.
- You typically receive no notification that you've been blocked — you only notice when messages stop being read or calls don't go through.
- The blocked person can still see your old messages but cannot receive new ones from you.
- Different apps handle blocking differently, so the visual cues you see depend on which platform you're using.
- If someone unblocks you, messages you sent while blocked will not retroactively appear in their chat.
How blocking works on the most common apps
iMessage (Apple's messaging service on iPhone, iPad, and Mac) will show your voice message as "Delivered" even if the recipient blocked you. You won't see a "Not Delivered" error. The only way to know for certain is to try calling — a blocked caller usually hears a single ring followed by silence, or goes straight to voicemail.
WhatsApp shows a single gray checkmark next to messages sent to someone who has blocked you. A delivered message shows two gray checkmarks; a read message shows two blue checkmarks. If you see only one checkmark for hours or days, it's a sign the person may have blocked you, though it could also mean they're offline or have poor connectivity.
Telegram does not show read receipts by default, so you won't see checkmarks at all. If someone blocks you on Telegram, you can still see your old messages in the chat, but you won't be able to send new ones — the send button will fail silently or show an error after a delay.
Signal and Google Messages behave similarly to WhatsApp, showing delivery status through checkmarks. A blocked message typically stays at one checkmark indefinitely.
Why you might not realize you've been blocked right away
Most blocking is silent by design. Apps don't send you a notification saying "This person blocked you" because that would defeat the purpose of blocking — the person wants to cut off contact without confrontation. Your app continues to work normally from your perspective; it's only the other person who stops receiving your messages.
You might notice over time that someone never reads your messages, never responds, or their status updates stop appearing. On apps that show when someone was last active (like WhatsApp or Messenger), you might see that they're active but not replying to you specifically. These patterns can suggest blocking, but they can also mean the person is busy, lost interest, or switched to a different app.
The most reliable way to know is to ask someone else to try contacting them, or to call the person directly. A blocked call often produces a specific sound — usually one ring followed by silence, or a message saying the number is unavailable.
What happens if you keep trying to send messages
Sending multiple voice messages to someone who has blocked you won't change anything. Each message will appear to send from your end but will never arrive. Some apps will eventually stop showing the "sent" status and instead show an error, but others will continue showing "sent" indefinitely.
Repeatedly trying to contact someone who has blocked you may trigger additional protections. On some platforms, if you try to create a new account or use a different number to contact the same person, the app's spam detection may flag your messages as spam or block them automatically. This is especially true on WhatsApp and Telegram, which have built-in protections against harassment.
Blocking versus other reasons messages don't arrive
A message that doesn't arrive could mean the person blocked you, but it could also mean several other things. If the person's phone is off or they have no internet connection, messages will queue and deliver later. If they've deleted the app or switched phones, messages might not arrive until they reinstall or set up their new device.
Some apps let users mute notifications from specific people without blocking them. In this case, the message arrives and is delivered, but the person simply doesn't see a notification and may not notice it for days. This is different from blocking, where the message never arrives at all.
If you're unsure whether you've been blocked or if something else is happening, the clearest test is to try calling. A blocked call produces a distinctive response that's hard to confuse with a normal "person is busy" situation.
What you can do if you think you've been blocked
If you believe someone has blocked you and you need to reach them, your options are limited. You could ask a mutual friend to pass along a message, or you could try contacting them through a different platform — though if they blocked you on one app, they may have done so on others as well.
You can also simply accept that the person doesn't want to communicate with you right now. Blocking is a tool people use to set boundaries, and respecting that boundary means not trying to find workarounds to contact them.
If you've been blocked by someone you need to reach for a legitimate reason — a work contact, a family member, a service provider — try email or a phone call instead. These channels are separate from the messaging app and may still be open.
Frequently Asked Questions
Can I tell if someone blocked me or just ignored my message?
Not always. If the person has read receipts turned on and your message shows as delivered but never read, they may have blocked you — but they could also be ignoring you. The most reliable indicator is calling: a blocked call produces a distinctive response, usually one ring followed by silence or a message that the number is unavailable.
If someone unblocks me, will they see the messages I sent while blocked?
No. Messages sent while someone had you blocked will not appear in their chat history. They'll only see messages you send after they unblock you. The blocked messages are essentially lost.
Can I block someone and still see their old messages?
Yes. When you block someone, you can still see the conversation history and all messages they sent before you blocked them. You just won't receive new messages from them, and they won't receive messages from you.
Does blocking on one app block me on other apps too?
No. Blocking is specific to each app. If someone blocks you on WhatsApp, they can still receive messages from you on iMessage, Telegram, Signal, or any other platform. You would need to be blocked separately on each app.
What if I accidentally block someone and want to unblock them?
You can unblock someone at any time through your app's settings. On most apps, go to the person's contact, look for a block or report option, and select unblock. Once unblocked, they'll start receiving your messages again, but they still won't see any messages you sent while they were blocked.
