Here's what's available and when it makes sense. ## At a glance# | You want | Get this | Price (USD) | Available on | | --- | --- | --- | --- | | Email in your sequences | Upgrade to **Multichannel** | $49 / month | — | | Another LinkedIn or Gmail/Outlook sender | **Extra LinkedIn/email seat** | $19 / seat / month | Multichannel, Agency / Team, AppSumo lifetime deals | | Another mailbox on your own mail server | **Extra SMTP/IMAP seat** | $2 / seat / month | Multichannel, Agency / Team, AppSumo lifetime deals | | More AI enrichment and writing | **Credit pack** | from $2 (100 credits) | Any paid plan | | Another teammate with their own login | **More Agency / Team seats** | $49 / seat / month | Agency / Team | | AI agents or a daily AI SDR | **Penny Agents** or **Penny SDR** | from $99 / month | Paid plans (see Penny add-ons) | | Save 24% | **Yearly** billing | — | Starter, Multichannel, Agency / Team, extra seats and Penny Agents | ## Extra LinkedIn/email seat# Each extra seat adds **one more LinkedIn account *or* one more Gmail/Outlook account** to your workspace. **Good for:** - Sending from a co-founder's LinkedIn as well as yours - Adding a second Gmail/Outlook mailbox to spread email volume - Running campaigns in two regions from two LinkedIn accounts An extra seat adds a **sending connection**, not a teammate login. For another person with their own login, use Agency / Team seats. **How to add:** 1. Go to **Settings → Billing**. 2. Under **Add more senders**, find **Extra LinkedIn or Gmail / Outlook seat** and set the number of **Seats**. 3. Click **Subscribe** (or **Buy**, or **Update extra seats** if you already have some) and complete checkout. 4. Connect the new account in **Settings → Accounts**. Extra seats can be bought on an active Multichannel, Agency / Team or AppSumo plan. They aren't available on Starter, Enterprise or Penny SDR All-in. Only owners and admins can buy them. ## Extra SMTP/IMAP seat# Each extra seat adds **one more custom mailbox** on your own mail server. Buy it the same way, under **Add more senders → Extra SMTP/IMAP mailbox**. **Good for:** - Spreading email volume across several mailboxes or domains to protect deliverability - Agencies sending from a client's own domain At $2 per mailbox, this is the cheapest way to scale email. Warm up each new mailbox before sending volume. ## AI credit packs# | Pack | Price (USD) | Per credit | | --- | --- | --- | | 100 credits | $2 | $0.02 | | 250 credits | $5 | $0.02 | | 500 credits | $10 | $0.02 | | 1,000 credits | $20 | $0.02 | | 2,500 credits | $45 | $0.018 | | 5,000 credits | $80 | $0.016 | Buy in **Settings → Billing → Credits**. Packs are for paid plans, and only owners and admins can buy them. Credits you buy never expire, and your plan's own credits are used first. See [AI credits](https://prosyo.com/fr/docs/ai/credits/). ## More Agency / Team seats# Each Agency / Team seat is **one teammate login + one LinkedIn + one mailbox**. Choose SMTP/IMAP, Gmail or Outlook for that mailbox. Campaigns, new people, AI credits, Intent people and storage also scale with each seat. Change the seat count on the **Agency / Team** card in **Settings → Billing** and click **Update seats**. See [Team seats and invites](https://prosyo.com/fr/docs/billing/team-seats/). ## When to upgrade# ### Starter → Multichannel# Upgrade when: - you want **email** follow-ups after LinkedIn (Starter is LinkedIn-only after the trial), - you've hit **1 active campaign** and want to test more, - you need more than **1,000 new people** or **100 AI credits** a month. **You get:** 1 email seat for an SMTP/IMAP, Gmail or Outlook mailbox, 3 active campaigns, 5,000 new people, 250 AI credits and 100 Intent people a month, 5,000 MB of storage, personalized video, and access to extra seats. ### Multichannel → Agency / Team# Upgrade when: - a **second person** needs their own login and LinkedIn account, - you run outreach for **several clients** and want a separate [client workspace](https://prosyo.com/fr/docs/billing/client-workspaces/) for each, - you need more campaigns, new people or credits than Multichannel includes. ## Penny add-ons# Choose **Penny Agents** for your own research, qualification and writing agents, or **Penny SDR** for a daily outreach workflow. Both add to a paid plan and use that plan's sending accounts. They do not add extra mailboxes, LinkedIn accounts or teammate logins. - **Penny Agents** works with any paid plan, monthly or yearly. - **Penny SDR** needs a plan with email (Multichannel, Agency / Team, Enterprise or an AppSumo lifetime deal), because it writes email. It's billed monthly and includes minutes on [Penny's computer](https://prosyo.com/fr/docs/ai/pennys-computer/). - A workspace has one Penny plan at a time. Switching between Penny Agents and Penny SDR replaces the old one. - Add-ons need a plan that's paid up. If your plan's payment is overdue, the Penny plans show "Paused until your plan is paid up. Your Penny settings are kept." **Penny SDR All-in** is a separate primary plan with one LinkedIn account and one mailbox, and it can start straight from your trial. See **AI Agents → Plans** for the current options, prices and allowances. While founding places last, the **Agent Penny** section shows **Founding price — locked for 12 months**. Once you've started a plan at that price, it shows **Founding price locked until** a date instead. If Penny plans aren't open to your workspace yet, the cards show **Join the waitlist** instead. AI usage is paid from your workspace's credits. See [Agents](https://prosyo.com/fr/docs/ai/agents/), [Set up Penny SDR](https://prosyo.com/fr/docs/ai/penny-sdr/) and [Plans and pricing](https://prosyo.com/fr/docs/billing/plans-and-pricing/#add-agent-penny-to-your-workflow). ## Common setups# | Situation | Recommended setup | Monthly (USD) | | --- | --- | --- | | Solo founder, LinkedIn only | Starter | $19 | | Solo founder, LinkedIn + email | Multichannel | $49 | | Founder + co-founder LinkedIn, one login | Multichannel + 1 extra LinkedIn/email seat | $68 | | Founder, LinkedIn + 3 cold-email mailboxes | Multichannel + 2 extra SMTP/IMAP seats | $53 | | 3-person sales team | Agency / Team × 3 seats | $147 | | Agency with 5 senders | Agency / Team × 5 seats + extra SMTP/IMAP seats per client | from $245 | ## Change or cancel# Upgrade, downgrade or cancel in **Settings → Billing**.
