Add-ons are paid on top of your plan, only if you use them. They are not part of the free trial: choose a plan first, then add them in **Settings > Billing**, under **Add-ons**. Only owners and admins can buy them. ## Email inboxes Each Gmail, Outlook or IMAP inbox your email steps send from is **US\$7 a month**. Pro and Agency can add inboxes; Starter and the free trial can't (email is part of Pro). Inboxes a Starter organization already pays for keep working. 1. Go to **Settings > Billing** and scroll down to **Add-ons**. 2. Under **Email inboxes**, choose the **Quantity** and click **Add inboxes**. Creem's secure checkout page opens: pay there and you come back to Kerux. 3. Back in Kerux, **Payment received. Your add-on appears here in a few seconds (refresh if it doesn't).** The card then shows how many inboxes you pay for and how many are connected. 4. Go to **Connect accounts**, scroll down to **Email inboxes** and connect them. See [Connect an email inbox](/help/getting-started/connect-email.md). The count is for your whole organization, across all its workspaces. When every inbox you pay for is connected, **Connect accounts > Email inboxes** tells you and shows **Add an inbox**, which opens Add-ons. ## WhatsApp numbers Each WhatsApp number your **Send WhatsApp** steps send from is **US\$7 a month**, on Pro and Agency. Starter and the free trial can't add numbers (WhatsApp is part of Pro), and a plan still in its trial period adds them once it is paid. It is always **your own WhatsApp number**: you connect it by scanning a QR code with your phone, like WhatsApp Web. Kerux doesn't provide numbers. 1. Go to **Settings > Billing** and scroll down to **Add-ons**. 2. Under **WhatsApp numbers**, choose the **Quantity** and click **Add numbers**. Creem's secure checkout page opens: pay there and you come back to Kerux. 3. Back in Kerux, **Payment received. Next, connect your number in Connect accounts > WhatsApp: scan the QR code with your phone.** The card shows how many numbers you pay for and how many are connected, and **Connect a number** while one is free. 4. Click **Connect a number** and scan the QR code. See [Connect WhatsApp](/help/getting-started/connect-whatsapp.md). The count is for your whole organization, across all its workspaces. Stopping a number works like an inbox (below): it keeps working until the end of the period already paid, then the most recently connected extra number is disconnected. On Starter the card says **WhatsApp numbers are an add-on on Pro and Agency (US\$7 a month each), not part of Starter.**; in a plan's trial period, **Not included in the free trial. Add numbers once your plan is paid.** ## Text messages (SMS) Text messages (SMS) are coming soon in Kerux. Nothing about them is sold or charged yet. ## Stop paying for an inbox or a WhatsApp number Each purchase is its own monthly subscription. To stop one, click **Manage or cancel subscription** in **Settings > Billing** and cancel it in Creem's customer portal. * **No refund, no proration.** The cancelled inbox keeps working until the end of the period you already paid for. Nothing is paid back for the days left. * **Settings > Billing > Add-ons** shows the cancelled inboxes and the date they work until. * **When the period ends**, if your organization has more inboxes connected than it pays for, Kerux disconnects the extra ones, **the most recently connected first**. The oldest ones stay connected. * **To choose which inbox stays**, remove the one you no longer want in **Connect accounts > Email inboxes** before the period ends. For example: you pay for 2 inboxes, both are connected, and you cancel one on the 10th. Both keep sending until the end of the month you paid for. Then the inbox you connected last is disconnected and the other one keeps working. A disconnected inbox stays in the **Email inboxes** list with the note **Disconnected by Kerux because it isn't paid for**. Email steps left on automatic send from your other connected inboxes; a step set to that inbox waits, and the contact shows why, until you pick another inbox in the step. To use it again, click **Add an inbox**, add one in **Add-ons**, then remove the disconnected inbox and connect it again. WhatsApp numbers work the same way: a cancelled number keeps sending until the end of the period already paid, then the most recently connected extra number is disconnected and shows **Disconnected by Kerux because it isn't paid for.** **Send WhatsApp** steps that use it wait until another number is connected. > [!WARNING] > > Cancelling or changing your plan doesn't cancel your inbox or WhatsApp add-ons: cancel them too in Creem's > customer portal. Without a paid plan, or once you no longer pay for any inbox or number, Kerux disconnects your > email inboxes and WhatsApp numbers. ## Kerux email finder credits (coming soon) The [Kerux email finder](/help/integrations/icypeas.md) finds a contact's verified work email from their name and company, without an account of your own. It is paid with email finder credits: | Pack | Price | | - | - | | 500 credits | US\$25 | | 2,000 credits | US\$80 | | 10,000 credits | US\$300 | * **Paid once, never expire.** No monthly fee and no credits included in the plans. * **1 credit per email found.** Nothing is charged when no email is found. * **0.1 credit to check an email the contact already has.** Checking an email the Kerux email finder just found is included. * **For the whole organization**, across all its workspaces. Only owners and admins can buy them, on a paid plan (not in the free trial). The **Kerux email finder** card in **Settings > Billing > Add-ons** shows your balance, the packs and every credit used or given back. The packs can't be bought yet: the card says **Coming soon. Until then, Find email steps work with your own Icypeas key.** To be told when they are ready, click **Add me to the waiting list** on the card. ## Coming soon: search credits The **Search credits** card is marked **Coming soon** too and can't be bought yet. To be told when it is ready, click **Add me to the waiting list** on its card; it then says **You're on the waiting list**. It is one sign-up for your whole organization and doesn't purchase anything. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
