Validation messages and budget minimums
What each message Koast shows before you launch means, including budget minimums, copy limits, Messenger and location radius.
Koast checks your campaign before it launches and tells you what to fix, next to the setting and in Review & Launch. This page lists those messages and the numbers behind them. Wherever a message shows a number in the app, it's filled in for you.
Budget minimums
| Ad account | Minimum | In the builder and Review & Launch | In a budget dialog |
|---|---|---|---|
| Meta | $1.00 a day | Daily budget must be at least $1.00 (100 cents) | Meta needs a daily budget of at least $1.00. |
| Meta | $7.00 lifetime | Lifetime budget must be at least $7.00 (700 cents) | Meta needs a lifetime budget of at least $7.00. |
The budget dialogs are the ones you open from Ads Manager or the builder to change a live budget. Budgets are in the ad account's currency.
Amounts with too many decimals
Meta holds money to a fixed number of decimal places, so Koast refuses an amount that's finer than that instead of letting Meta round it. You'll see one of these, with your ad account's currency:
| Message | When |
|---|---|
| Meta takes USD amounts to 2 decimal places. Round this amount and try again. | Any currency not listed below, for example a budget of 12.345. |
| Meta takes JPY amounts in whole units only. Round this amount and try again. | CLP, COP, CRC, HUF, ISK, IDR, JPY, KRW, PYG, TWD and VND, which Meta takes in whole units. |
Koast checks budgets, bid amounts and ad set spend limits when you launch, import or duplicate a campaign, when you update a budget in Ads Manager or the builder, when you publish changes to a live campaign, and when the agent changes a live budget. Round the amount and try again.
The budget, bid and spend limit fields in the campaign settings catch it while you type, and the budget dialogs in Ads Manager and the builder when you select Update or Update Budget. Under the field you'll see "Amounts in JPY take whole units only." or "Amounts in USD take at most 2 decimal places.", with your ad account's currency.
Copy limits
| Field | Meta |
|---|---|
| Primary text | 40,000 characters |
| Headline | 255 characters |
| Description | 500 characters |
Over the limit, you'll see "Headlines cannot exceed 255 characters", "Primary text cannot exceed 40000 characters" or "Descriptions cannot exceed 500 characters", with your ad account's number.
Name limits
| Ad account | Campaign name | Ad set name |
|---|---|---|
| Meta | No limit in Koast | 400 characters |
A name that's too long shows, for example, "This ad set name is longer than the 400 characters allowed."
Carousels and variations
| Message | What to do |
|---|---|
| Carousel ads require at least 2 cards | Add a second creative to the carousel. |
| Carousel ads support maximum 10 cards | Remove cards until you're at 10 or fewer. |
| Maximum 5 headline variations allowed | Keep 5 headlines at most. The same goes for primary text and descriptions. |
| Duplicate headlines are not allowed | Make each headline different. The same goes for primary text and descriptions. |
Lead forms and ad accounts
| Message | What to do |
|---|---|
| Select a lead form, or turn off instant forms and send people to a website instead. | Pick a lead form, or switch instant forms off. |
| Add a destination URL, or turn on instant forms to collect leads without one. | Add the URL, or switch instant forms on. |
| Select a conversion event, or turn on instant forms to collect leads without one. | Pick the conversion event, or switch instant forms on. |
| No ad account is connected to this brand. Connect one, then launch again. | Connect an ad account to the brand you're launching from. |
| That lead form draft no longer exists or is not valid. Open the lead form builder and save it again. | Build the form again with Build a new form here and pick the new one. |
| This ad platform only accepts instant forms built in its own ads manager. Pick one of its existing forms instead. | Pick a form that already exists on the page. |
| This campaign is in another ad account. Import it into that account, or pick one from the ad account this launch uses. | Import campaigns from the ad account you're launching to, or switch to the other ad account and import it there. |
Meta ad accounts use forms made in Meta. See Lead campaigns.
Messenger
With MESSENGER on, your ads open a chat, so some options don't fit. See Messenger.
| Message | What to do |
|---|---|
| Messenger ads cannot use the Leads objective. Pick Sales or Traffic, or turn off Messenger. | Set the objective to Website Conversions or Traffic, or turn Messenger off. |
| Messenger ads cannot be built from an existing post. Use an image or video creative, or turn off Messenger. | Use an image or video instead of an existing post. |
| Messenger ads support a single image or video. Change carousel ads to a single creative, or turn off Messenger. | Change carousels to single image or video ads. |
| Messenger ads use one image or video for every placement. Remove the placement versions, or turn off Messenger. | Remove the placement-specific versions of the creative. |
| Messenger ads support one headline, one primary text and one description. Keep one of each, or turn off Messenger. | Keep one variation of each. |
| Messenger ads cannot run in the right column placement. Remove that placement, or turn off Messenger. | Untick the Right Column placement. |
| Messenger ads optimise for conversations, which carry no purchase value. Pick another bid strategy. | Pick a bid strategy other than Highest Value. |
| The Messenger welcome message can be at most 300 characters. Shorten it. | Shorten Messenger Welcome Message (Optional). |
| Messenger ads can only go into a new ad set. Add them to a new ad set, or turn off Messenger. | Add the ads to a new ad set instead of an existing one. |
| Messenger ads open a chat, so they cannot promote a catalog product. Remove the shop product, or turn off Messenger. | Remove the catalog product. |
Location radius and pins
Koast checks every radius and pin in Locations and Excluded Locations. The messages name the location, for example:
| Message | What to do |
|---|---|
| "Austin": radius must be between 10 and 50 miles for cities on Meta. | Keep a city's radius from 10 to 50 miles, or 17 to 80 km. |
| "Downtown store": radius must be between 0.63 and 50 miles for pinned locations on Meta. | Keep a pin's radius from 0.63 to 50 miles, or 1 to 80 km. |
| "Downtown store" is a pinned location without a radius. | Give the pin a radius. |
| "Downtown store" is a pinned location without coordinates. | Edit the pin on the map and place it again. |
| Meta does not accept a radius on region locations ("California"). | Remove the radius. Only cities and pins take one. |
| "Austin": choose miles or km for the radius. | Pick mi or km next to the radius. |
Next to the field, the same problems read "Radius must be between 10 and 50 mi for cities." and "A pinned location needs a radius." See Add a radius or drop a pin.
One campaign per batch
When you build with the agent, each campaign draft holds exactly one campaign. If you ask for a second one in the same draft, you'll see:
Start a new campaign for the second one.
