A good Slack alert message says what broke, how badly, compared with what, over which days, and where to look, in three lines or fewer. Below are six example messages to copy into your own scripts or tools. We wrote them, and every ad name and number is made up.

## What makes an alert readable

1. **The ad, ad set or campaign name first.** People scan for names they own.
2. **The number against the threshold.** "1,420 > 900" beats "CPA is high".
3. **The window.** "Last 3 days" tells you it is not a one-hour blip.
4. **A severity.** High, Medium or Low, so people know what to read first.
5. **One link.** Straight to the place to fix it.

## Six examples

**1. High cost per result**

```
HIGH  High CPA  |  Goa retargeting (ad set)
Cost per result Rs 1,420 > Rs 900 (last 3 days)
Spend Rs 7,100, 5 leads.  Open in Ads Manager
```

**2. Spend with no results**

```
HIGH  Spend with no results  |  Kerala lookalike (ad set)
Spent Rs 1,350 today, 0 leads. Target cost per lead Rs 600.
Check the form and the website first.
```

**3. CTR falling**

```
MEDIUM  CTR falling  |  Monsoon reel 02 (ad)
CTR 1.1%, down 31% vs previous 7 days (52,000 impressions)
Frequency 3.2. Time for a new hook.
```

**4. Google Ads campaign with no conversions**

```
Google Ads alert, yesterday
Dubai Packages: spent Rs 6,240, 0 conversions
Brand Search: spent Rs 5,180, 0 conversions
```

**5. Monthly pace**

```
MEDIUM  Monthly spend check  |  Northwind Escapes
Rs 1,82,000 spent by 15 Nov, expected Rs 1,50,000 (21% ahead)
At this pace the budget runs out around 25 Nov.
```

**6. Connection problem**

```
Ad account connection problem  |  Wanderlast Holidays
Reports can't read the Meta ad account. Reconnect it to restart reports and alerts.
```

We make Marxx. It always posts a message like example 6 when an ad account needs reconnecting, and its alert digests lead with a count, such as "2 alerts triggered, High 1, Medium 1", with Snooze 7 days and Turn off in the menu. See [Meta ads alerts in Slack](/guides/how-to-set-up-meta-ads-alerts-in-slack).

## Before and after

| Hard to read | Easy to read |
|---|---|
| "Alert: CPA threshold exceeded for account 2391" | "HIGH High CPA, Goa retargeting: Rs 1,420 > Rs 900 (last 3 days)" |
| "Campaign performance changed" | "CTR down 31% vs previous 7 days, Monsoon reel 02" |
| Ten messages, one per ad | One message listing all ten |

The last row matters for scripts. Slack allows about one message per second per channel, so send one summary, not one message per ad. A daily digest that groups every alert into one message does the same job.

## Tips

- **Use words, not only colours or emoji.** Phone notifications can drop formatting, so the words must carry the meaning.
- **Put the fix hint in the message** when it is obvious, as in example 2.
- **Write rupees the same way every time,** so numbers line up when people scan.
- **Thread the follow-up.** Replies under the alert keep the channel clean. See [CPA](/glossary/cpa) and [CTR](/glossary/ctr) if a metric needs explaining to the team.

## FAQ

### Should alert messages tag a person?

Tag someone only on High alerts, and only the person named in your escalation plan. Tagging on every alert makes people mute the channel.

### How long should an alert message be?

Two or three lines. Put detail behind the link.
