Priced per reply. Measured in meetings.

Which plan do I need?

Tell us how you send. We'll fill in the rest and work out the credits.

Who are you sending for?

Clients

Each client gets its own workspace.

Where do you send?

How do you want to enter your volume?

Mailboxes per client

Sending inboxes, across every tool you use. There is no cap on how many you connect.

Emails per mailbox per day

Most teams keep each mailbox under 20 a day. Azure or Outlook tenants with many mailboxes on a domain usually send 2 to 3 each. Mixed setup? Switch to entering volume sent.

Which replies get an answer?

Every reply is still read and categorised. This sets which ones get a drafted answer.

Not sure about these? Leave them. They're typical for cold outreach, and you can change any of them if you know yours.

Email reply rate

Share of emails that get any reply. Your sending tool shows this per campaign.

Replies that are positive

Interested, asking a question, or open to a call. About 1 in 5 replies.

Positive leads that book a meeting

The agent proposes times, negotiates, and sends the invite. About half of positive leads end up booked.

Replies per conversation

How many times a lead writes back before the meeting is booked. Each one is read and answered.

Follow-ups per lead

Sent when a lead goes quiet. Counted as if every lead goes quiet, so this is the most it can cost.

Sending days per month

Weekdays only, minus a few days off, is about 20.

How credits work

The platform is included. Credits only pay for the replies your agents read and answer.

0.5

Read a reply

The Understanding Agent classifies it and scores the sentiment.

Draft a response

The Drafting Agent writes it in your voice from your knowledge base.

EXAMPLE

1,000 replies a month uses about 1,400 credits.

Every reply is read; the 1 in 5 that are positive get two answers and two follow-ups.

Pricing questions

What is a credit?

Credits pay for the work inbox agents do. Understanding a reply costs 0.5 credits and drafting a response costs 1 credit, so a reply that is read and answered costs 1.5 credits.

How does Underfive book meetings?

When a lead is interested, the inbox agent proposes real times from your connected calendar, handles the back-and-forth, and sends the invite from your calendar. The thread is tagged Meeting Scheduled in the Unified Inbox. You can also share a Calendly or Cal.com link instead.

Do I pay per seat, per mailbox, or per agent?

No. Every plan includes unlimited team members and unlimited inbox agents, and there is no cap on how many mailboxes or LinkedIn senders you connect through your sending tools. Plans differ by how many credits are included each month and how many workspaces you can run: 1 on Professional, 5 on Growth, 10 on Business and unlimited on Agency.

Is the Unified Inbox included on every plan?

Yes. Every plan includes the Unified Inbox across every sending tool and client, inbox agents, meeting booking, follow-ups and approvals. The MCP server, the API and webhooks are included from Growth up.

What happens if I run out of credits?

You can move up a plan at any time. If you need more than the Agency plan includes, contact us and we will size a custom plan to your reply volume.

Is there a free trial?

Yes. You start with 50 free credits and no credit card, so you can connect a sending tool and watch real replies get handled before you pick a plan.

Do you offer annual billing?

Yes. Pay annually and save 20% on any plan.

Can you run it for us?

Yes. With the managed service our team handles every inbound reply on your behalf, from qualifying to booking, on the same Unified Inbox.
