| Which plan to pick | Growth is enough for a small team that just needs a tidy shared inbox with AI help. Choose Pro if you need response-time targets, CRM or Shopify data next to each email, or the API. Voice is an add-on at $30 per seat. | Multichannel is the best value if you use LinkedIn at all, since the add-ons on Email Volume quickly cost more. Only look at Jason AI SDR once your manual sequences are already booking meetings. | Start on pay as you go with the free credits, build one agent for your most common call and test it on your own phone. Talk to sales only once you run thousands of minutes a month. |
