# How to send one WhatsApp message and use the Message Queue

> Wassuply's Send Message tool sends a single WhatsApp message from one of your connected numbers to any number you type, with an optional image or video, without saving that number as a contact. The Message Queue is a live view of every running or paused campaign: its pending contacts, the numbers taking turns, and pause, resume and stop buttons.

In the app: Sidebar → Tools → Send Message / Message Queue

## Key facts

- Wassuply's Send Message tool needs a connected number, a recipient number of at least 7 digits including the country code, and some message text.
- Send Message attachments in Wassuply can be JPG, PNG, GIF, WebP, MP4, MOV or AVI files, sent with the message as the caption.
- Send Message in Wassuply fills {name} with Test User, {custom1} with Sample1 and {custom2} with Sample2, and picks one option from any spintax.
- Send Message does not save the recipient as a contact and does not check the opt-out list, the blacklist or daily limits.
- The Wassuply Message Queue lists running and paused campaigns only, refreshes every 3 seconds and shows the next 8 pending contacts of each one.
- The Message Queue has no per-message cancel or retry: retries are on the campaign's own page, and opt-outs and blacklist entries are re-checked right before every campaign send.

## What is the Send Message tool?

Send Message sends one WhatsApp message, right away, from a number you pick to a number you type, outside any campaign. Use it to test a newly linked number, answer someone quickly or contact a single person without building a list.

It has no waits, batches or schedule, and nothing is added to Contacts or to a campaign. For more than a handful of people, use a [broadcast campaign](https://wassuply.com/docs/broadcast-campaigns/), which paces every message and respects daily limits.

## How do I send a single WhatsApp message?

Open **Tools → Send Message**, pick a number, type the recipient and the message, then click **Send Message**.

**How to send one WhatsApp message with Wassuply**

1. **Open the tool**: In the sidebar, go to **Tools → Send Message**.
2. **Choose the sending number**: Under **Send from account**, click a number. Only connected numbers can be chosen, and the first connected one is selected for you.
3. **Enter the recipient**: Type the full number with the country code in **Recipient phone number**, for example 447712345678. Spaces and the + sign are removed.
4. **Write the message**: Type in **Message**. The counter shows characters out of 4,096 and turns red above 4,000.
5. **Add a file if needed**: Click **Attach image / video (optional)** and pick a JPG, PNG, GIF, WebP, MP4, MOV or AVI file. The message becomes its caption.
6. **Send**: Click **Send Message**, or press Enter in the phone box. The button changes to **Sent!** or **Failed - try again** with the error underneath.

Below the button, **Will send via** names the number in use. Each send is added to **Recent sends this session**, which keeps the last 20 while you stay on the screen and is not saved.

## How does Send Message handle numbers, files and variables?

Send Message uses the same sending steps as a campaign, without the pacing and list checks.

- **Numbers you never chatted with**: The number does not need to be saved on either side. Wassuply finds the chat in your chat list or opens it through WhatsApp's New chat panel, and for a text message can fall back to WhatsApp's own click-to-chat link.
- **Message box check**: The open chat is checked against the number, and the message box must hold exactly your message before Send is pressed. Otherwise nothing is sent and you see the error.
- **Variables and spintax**: `{name}` becomes Test User, `{phone}` the recipient's number, `{custom1}` Sample1 and `{custom2}` Sample2. Spintax such as `{Hi|Hello}` sends one option, picked at random. See [templates and spintax](https://wassuply.com/docs/templates-and-spintax/).
- **Attachments**: Images and videos only. Text is still required, and it is sent as the caption. To send a PDF or Word file, use a campaign attachment.
- **Busy numbers**: A number that is running a campaign, a warm-up, a group job or another short task is refused with a message saying what it is busy with.
- **What it does not check**: The opt-out list, the blacklist and daily limits. Check the number yourself before sending; see [opt-outs and blacklist](https://wassuply.com/docs/opt-outs-and-blacklist/).

> **Tip:** Your plan must be active on this computer to send; see [plans, licences and devices](https://wassuply.com/docs/plans-licences-devices/).

## What does the Message Queue show?

The Message Queue (**Tools → Message Queue**) shows one card for every cold or broadcast campaign that is running or paused, and refreshes every 3 seconds; **Refresh** reloads it at once. With nothing running or paused, it reads **Queue is Empty**.

| On each card | What it shows |
| --- | --- |
| Name and badge | Campaign name, **RUNNING** or **PAUSED**, and the campaign type. |
| Progress | Percent complete and sent out of total contacts. The bar turns amber above a 10% failure rate and red above 20%. |
| Sent, Failed, Pending, Fail Rate | Counts so far. Fail Rate is failed divided by sent plus failed. |
| Rotating | The numbers the campaign takes turns with, green when connected. |
| Show next N in queue | Up to the next 8 pending contacts (phone and name) in send order, plus how many more are pending. |

The queue covers campaigns only. Sequence and drip steps are listed on each sequence's own page ([Sequences and Drip](https://wassuply.com/docs/sequences-and-drip/)), and Send Message sends never appear here. For exact waits and send times, open the campaign's **Send schedule**.

## How do I pause, resume, stop or retry from the queue?

Each card has **Pause** or **Resume**, a stop button and a button that opens the campaign's page.

- **Pause** holds the campaign, even partway through a wait. **Resume** needs at least one connected number, and none of the campaign's numbers busy with another campaign, a warm-up or a group job.
- Stop ends the campaign immediately, without a confirmation. Its unsent contacts stay unsent and can only go out through **Re-run N unsent** on the campaign page.
- Retry for failed contacts, Resend for sent ones and **Retry N failed** are on the campaign page; see [broadcast campaigns](https://wassuply.com/docs/broadcast-campaigns/).
- There is no per-message cancel. To keep one person from being messaged, add the number to your opt-out list or blacklist: Wassuply checks both again right before every campaign send and skips the contact.

## What statuses can a queued contact have?

Every contact in a campaign is pending, sending, sent, failed or skipped; the campaign page filters them by All, Sent, Failed and Pending.

| Status | Meaning |
| --- | --- |
| Pending | Waiting its turn. These are the contacts shown in the queue. |
| Sending | Being sent right now. If Wassuply closes at this moment, the contact is marked failed rather than sent twice. |
| Sent | The message box held exactly the message and Send was pressed. This is not a delivery receipt. |
| Failed | The send did not happen, with the reason shown. It can be retried. |
| Skipped | Not sent on purpose: opted out or blacklisted, not on WhatsApp (when validation is on), or messaged by another campaign within the cross-campaign cooldown. |

Delivered and read ticks are counted separately, when you press **Check Receipts** on the campaign page. If many contacts fail, see [troubleshooting](https://wassuply.com/docs/troubleshooting/).

## Frequently asked questions

### Can I send a WhatsApp message without saving the number?

Yes. Type the full number with the country code in Send Message and click **Send Message**; Wassuply does not add it to Contacts or to your phone's address book.

### Can I send a PDF or document with Send Message?

No. Its file picker accepts images and videos only. A campaign attachment accepts PDF, DOC and DOCX.

### Does Send Message respect my daily limit and opt-out list?

No. It sends straight away without checking daily limits, opt-outs or the blacklist, so keep it for single messages and use a campaign for lists.

### Can I send to several numbers at once with Send Message?

No, one recipient per send. For a list, create a [broadcast campaign](https://wassuply.com/docs/broadcast-campaigns/), which paces the messages.

### Why does Send Message say the account is busy?

That number is running a campaign, a warm-up, a group job or another short task, and one number only does one thing at a time. Pick another number or wait until it finishes.

### Why is the Message Queue empty while a sequence is sending?

The queue only lists running and paused campaigns. Sequence steps are shown on each sequence's page.

### Can I cancel a single message in the queue?

No. Add the number to your opt-out list or blacklist and Wassuply skips that contact when its turn comes. A started campaign's contact list cannot be edited.
