On Messenger, a white checkmark inside a circle means your message has been sent from your device but not yet delivered to the recipient's device, often because they're offline, have their phone off, or are using a restricted account. This contrasts with a filled blue circle (delivered) or a profile picture (read).
Those check mark icons that you see after you've sent a message on messenger aren't just random. Web — an empty check on messenger means that your message has been sent but has yet to be delivered to the intended person.
This means the message has been sent, but is not yet delivered, and the recipient cannot view it. The third is a filled-in blue circle with a white checkmark, which means your message has been delivered, and is currently on the recipient's phone, though he or she is yet to view it.
Messenger uses simple symbols to show what's happening behind the scenes: Sent: The message has left your device. Delivered: The message has reached your recipient's device. Seen: You'll see a small profile photo where the checkmark was once displayed. This is confirmation that your message has been read.
Engorged Ticks
In most cases, the term “white tick” typically refers to an engorged tick. Note that this description applies to all types of ticks, not just any one particular species. As ticks eat, their bodies expand and turn white, coining the term “white tick.”
If you see white ticks, they are simply engorged.
Ticks that are engorged with blood can look a whiteish or light gray color, but there are no species of ticks that are inherently white. Surprisingly, some ticks can even appear purple! There is one tick with a white dot, which is known as the lone star tick.
If it turns to two checkmarks, your text message has been delivered to the recipient. Or, your message has been read if the checkmark turns blue.
White check means it's not delivered correctly or they have you restricted. Most likely that it's sent and not delivered though due to them not being signed in anywhere or not on Wi-Fi date on their phone where they are signed in. Their phone can't receive it without the internet though so it stays white.
You can tell if someone restricted you on Messenger by noticing key changes: their activity status disappears, messages only show as "Sent" (never "Delivered"), calls go unanswered (no ringing), profile photos might seem missing to you (though visible to others), and you can't see their read receipts or online status, but the crucial sign is they still see your messages (they just go to their Message Requests), unlike a block where messages don't deliver at all.
The color of your messages in Messenger depends on the communication method used. Green messages are typically SMS or MMS messages sent to non-Facebook users, while blue messages are sent within the Messenger app to your Facebook friends.
Practical signs someone may have muted you
No active status updates or last active timestamps: Messenger's “Active now” or “Last active” indicators can be unreliable, but if they appear online frequently yet ignore your DMs while responding to others, mute is possible.
A checkmark with a GREY background means a message has been sent but not delivered. A checkmark with a BLUE background means a message has been delivered. Hope this helps.
Black means it hasn't been received, white does.
Facebook does not notify users when they're muted. You can't check muting status through settings—it's private. Muting is different from blocking (blocked users can't message you at all).
Empty circle with a check mark: The message has been sent but not delivered to the recipient. Filled circle with a check mark: The message has been delivered.
5 The recipient is not logged into Facebook
If Messenger shows "Sent" but not “Delivered,” it may be because the recipient isn't logged into Facebook. This could mean that their account was deleted, deactivated, or that they haven't logged in recently.
If you see "This person is unavailable on Messenger" when you open a chat, they've likely blocked you on Facebook, which also blocks you on Messenger. If you try to send a message and get a notice that the other user isn't accepting messages, you've likely been blocked on Messenger.
The profile, Page or group you've snoozed won't know that they've been snoozed. You can only snooze someone from a post in your Feed.
When you're restricted on Instagram, the following happens:
The next stage is the empty circle with a check that means that the message is sent to the Facebook servers but has not been delivered yet. The full circle with check is that the message is delivered but not read.
You can tell if someone restricted you on Messenger by noticing key changes: their activity status disappears, messages only show as "Sent" (never "Delivered"), calls go unanswered (no ringing), profile photos might seem missing to you (though visible to others), and you can't see their read receipts or online status, but the crucial sign is they still see your messages (they just go to their Message Requests), unlike a block where messages don't deliver at all.
Messages Only Show One Tick
What you might notice: One grey tick, but never two. What it could mean: They've blocked you or their phone's off, they've deleted WhatsApp, or they've got no signal.
To know if someone blocked you, watch for calls going straight to voicemail after one ring, texts showing "Not Delivered" (or no read receipts/checkmarks on apps like WhatsApp), and potential changes on social media; the most definitive test is calling from another number, where it rings normally for you but goes to voicemail on your original number, indicating a block.
When read receipts are turned on, the sender sees the word “Read” below messages they've sent to you, indicating that you've read their message. If you haven't read their message, the sender sees “Delivered.” You can turn on read receipts for everyone or for individual contacts.
