When you’re blocked, your messages usually do not reach the other person, but what you see on your screen (sent/delivered/read) depends a lot on the app and the phone you’re using.

Quick Scoop: Do messages deliver when blocked?

In most modern messaging systems, blocking works like a one‑way wall:
Your messages may look “sent” (and sometimes even “delivered”) to you, but they are silently discarded and never shown to the person who blocked you.

Key idea:

  • “Delivered” = often just “reached a server or network,” not “they actually saw it.”

How blocking behaves by platform

Regular SMS / text (Android, general carriers)

  • Many Android setups: if you’re blocked, your text is sent from your phone but never reaches their inbox.
  • Often:
    • You may see “sent,” not “delivered” (if your app uses these labels).
* Some phones put your message into a hidden “blocked” or “spam” folder on the recipient’s device, never showing it to them.
  • Some carriers/apps treat “delivered” as “made it to the carrier’s server,” not “appeared on their phone,” so you might still see a “delivered” flag while the blocked phone silently drops it.

Android to Android (Google Messages, Samsung Messages)

  • Google Messages: blocked messages are typically not received; the sender usually doesn’t get a clear “delivered” or “read” status.
  • Samsung Messages: blocked SMS/MMS are often sent directly to a blocked/hidden folder; again, the sender usually only sees “sent,” not a confirmed “delivered.”

iPhone / iMessage patterns (practical reality)

Apple doesn’t spell out the details publicly, but user reports and tech explainers line up with this pattern:

  • If someone blocks you:
    • Your iMessages to them generally stop showing “Delivered” under the bubble.
    • They never see those messages in their conversation.
  • There are edge cases where a message can show “Delivered” if it hit the system before the block fully took effect, but once the block is in place, new messages aren’t actually delivered to their inbox even if the status looks confusing.

Social and chat apps (WhatsApp, Messenger, Snapchat, Signal)

Each app has its own twist, but the goal is similar: block = cut off communication.

  • Facebook Messenger:
    • When blocked, your messages do not appear in their inbox and you lose access to their active/online status.
  • Snapchat:
    • If you’re blocked, snaps and messages won’t be delivered, and they won’t show as “opened” or properly “delivered.”
  • Signal:
    • Blocking prevents messages and calls; the sender doesn’t get delivery/read indicators in the usual way.

In all of these, blocking is meant to be quiet: you don’t get a pop‑up saying “you’re blocked,” you just stop getting clear delivery and read feedback.

Why “Delivered” can still appear

This is where most confusion comes in and where a lot of forum threads and debates in 2024–2025 come from.

Behind the scenes:

  • Some systems mark “Delivered” when:
    • The message reaches a server (like iMessage or an SMS center), or
    • The carrier accepts the message for the destination number.
  • Blocking often happens on the device or app level:
    • The network may say “yes, I passed it along,” but the phone/app then throws it away because you’re blocked.

So you can get this strange situation:

Your phone: “Delivered”
Their phone: message silently dropped, never shown

This is particularly noted in some Android–iPhone combinations and various SMS setups where blocking is implemented after the network step.

Do messages send later if you’re unblocked?

  • Messages sent while you were blocked are generally gone for good.
  • Unblocking usually only affects future messages; anything sent during the blocked period will not suddenly appear once they unblock you.

How to tell if you might be blocked (without obsessing)

There’s no 100% technical test, but common signs people talk about in recent discussions include:

  • Messages that used to show “Delivered” or read receipts suddenly stop doing so for a long time.
  • No replies across multiple days or attempts, even though they’re active elsewhere.
  • On some apps, loss of profile picture, status, or “last seen” visibility (depending on privacy settings).

These can also be caused by:

  • Network issues
  • Phone turned off or on Do Not Disturb
  • Changed privacy settings

So it’s better to see them as hints, not proof.

Mini FAQ

Q: So, do messages deliver when blocked?

  • In most practical cases, no — they don’t reach the other person’s inbox.
  • You might still see “sent” or even “delivered,” but that doesn’t mean they saw it.

Q: Can I force a blocked message through somehow?

  • No. Blocking is specifically designed to prevent that. Persistently trying to bypass a block can cross into harassment, especially if there’s prior conflict or a work relationship involved.

Q: What’s the healthiest move if I think I’m blocked?

  • Take it as a sign to respect their boundary.
  • If you genuinely need to talk (shared kids, legal/financial issues, work), use an appropriate, neutral channel and keep it minimal and respectful.

Bottom line: If someone has blocked you, assume your messages won’t truly deliver—no matter what your phone claims.

TL;DR:
Most of the time, when you’re blocked, your messages do not reach the other person, even if your screen says “sent” or occasionally “delivered,” because those statuses often only confirm network/server handling, not that the person actually got or read your message.
