Email and WhatsApp broadcasts are part of Pro and Agency (and the free trial). Services you connect with your own account and pay to that provider directly can be used during the free trial. Add-ons billed by Kerux (email inboxes and WhatsApp numbers) are not included in the free trial. On Starter, sending one says **This is part of Pro. Upgrade in Settings > Billing; anything you already set up keeps working.** See [Plans and billing](/help/account/billing.md). A **broadcast** is one message, on one channel, to a [segment](/help/leads/segments.md) or a list: news for your customers, an invitation to a webinar, a seasonal offer. It is a campaign with a single step, so it works exactly like your other campaigns: each LinkedIn account's daily limits and pacing, the campaign's working hours, your [sending rules and consent](/help/campaigns/sending-rules-and-consent.md), and never a message with an empty variable. ![A new LinkedIn broadcast to a segment, reviewed: who it reaches and how long it takes](https://mintcdn.com/kerux-f37add41/HjnACOD6o_hGSzwc/images/broadcasts.png?fit=max\&auto=format\&n=HjnACOD6o_hGSzwc\&q=85\&s=efad5aba223ddac91e304212fc821c61) ## Send a broadcast **1. Open Broadcasts** Click **Campaigns**, then **Broadcasts**, then **New broadcast**. Or, in **Contacts > Segments**, click **Broadcast** next to a segment. **2. Choose the channel** * **LinkedIn message**: only your 1st-degree connections get it; the others are skipped. * **Email**: from your connected inboxes, ending with the short line on how to unsubscribe and your postal address (see [Write and send emails](/help/campaigns/send-email.md#the-footer-and-the-unsubscribe-link)). It needs a subject, and a postal address in **Settings > Sending rules**. * **SMS**: coming soon. The card says **Coming soon: text messages aren't available in Kerux yet.** and can't be picked. * **WhatsApp**: from your connected WhatsApp numbers (your own numbers, connected with a QR code: see [Connect WhatsApp](/help/getting-started/connect-whatsapp.md)), only to people with recorded consent, at each number's daily pace (up to 100 messages and 40 new chats a day, fewer in a number's first weeks: see [Limits](/help/getting-started/connect-whatsapp.md#limits)). Keep WhatsApp broadcasts to people who know you and expect your message: cold mass messages get numbers banned. **3. Choose who gets it** **A segment** or **A list**. The number of contacts in each is shown. One broadcast reaches up to 5,000 people (the first 5,000 added to Kerux). For a bigger audience, send it, then click **Send to the next 5,000** on it (see [More than 5,000 people](#more-than-5000-people)). **4. Write the message** Variables like `{{contact.first_name}}` are filled for each person (see [Variables](/help/campaigns/variables.md)). Someone with an empty variable and no default waits until the data is there instead of getting a message with a hole. **5. Choose when** **Now**, or **At a date and time** (in your computer's time zone). Either way it goes out within the campaign's working hours: Monday to Friday, 9:00 to 18:00, unless you change them in its settings. **6. Review, then send** Click **Review**. The draft is saved and Kerux shows how many people it reaches, the same preflight as a campaign launch (problems in red, each with a **Fix** link) and how long it takes: for LinkedIn, when the first and last messages go out per account; for email and WhatsApp, how many inboxes or numbers send it, how many a day and how many working days it takes. Then click **Send now** or **Schedule**. A broadcast is sent once. People who join the segment later don't get it; to reach them too, use a campaign with **Also add people who match later** (see [Smart segments](/help/leads/segments.md#use-a-segment-as-a-campaigns-audience)). ## More than 5,000 people When the audience has more than 5,000 people, the review says **(the first 5,000; once it is sent, "Send to the next 5,000" on it reaches the rest)**. After you send it: **1. Open the broadcast** Click **Campaigns > Broadcasts** and open the one you sent. **2. Click Send to the next 5,000** A new broadcast opens with the same channel, audience and message, named **(next 5,000)**. It leaves out everyone the first one went to, so it reaches the next 5,000 people in the audience and nobody gets it twice. **3. Review, then send** Change the message or the time if you like, then **Review** and **Send now** or **Schedule**. If the audience is still bigger, the new one shows **Send to the next 5,000** too, and each one leaves out everyone the earlier ones went to. Each broadcast can be continued once (two "next" broadcasts would pick the same people); once it is, it shows **Continued in the next broadcast**. Picking another segment or list in the new one makes it a fresh broadcast that leaves nobody out. A plain **New broadcast** to the same segment or list is a new message for everyone in it (for example next month's news): it starts again from the first 5,000. ## Follow it **Campaigns > Broadcasts** lists them: **Draft**, **Scheduled**, **Sending**, **Done** or **Paused**. Open one to see how many people it went to, **Got it**, **Still to go** (waiting for limits, working hours or missing data) and **Didn't get it** (not a connection, no email or phone, sending rules). **Open its campaign** shows each person's status and the reason, like any campaign, and that is where you pause it. A broadcast also shows in your **Campaigns** list, with the same name. ## API `POST /v1/broadcasts` creates a draft, `GET /v1/broadcasts/{id}/check` returns the preflight and the forecast, and `POST /v1/broadcasts/{id}/send` sends it (once; it starts everyone in the audience, so the key or connected app needs the permission to start campaigns, **enrollments:write**, too). For the next 5,000, create a new one with `continues_from` set to the sent broadcast's id; a broadcast says `more` (its audience had more people) and `continued_by`.
