Those two things are completely separate, and that is the whole answer: your agent's inbox is an address of its own, your Claude subscription is only the engine that reads it, and neither depends on the other. The number of subscriptions you're paying for stays exactly the same, what changes is only which mailbox the agent reads and writes through.
This is one of the questions we hear most often, almost always stuck in the exact same place: "my Claude account runs on my email, but the autonomous agent has its own email, how do I connect it to a different email account from the same Claude" (a real question from our community, asked in slightly different words over and over). The hidden assumption there is that the agent's identity lives on your Claude account, and it's exactly the opposite: its identity lives in the mailbox, and the account is just who is allowed to log into it.
So what do you actually do: open the agent a real inbox, owned by it and not by you, even a free account is enough, then connect that inbox through the same standard connection any outside tool uses, without opening a second subscription. On our team this is how every role got a separate identity from day one, Adam has a mailbox, Maya has a mailbox, Neo has a mailbox, each with an address mail reaches directly instead of landing in mine (which also makes it instantly clear who's on the hook when something falls through the cracks).
Where people actually get stuck is almost never the technical part, it's that nobody ever wrote this step down explicitly. I watched someone in the group solve it on her own, quietly, with an address that was really just an alias pointing at one inbox she already had, cheap and clean, and because nobody asked her how, nobody copied it either.
Stop for a second before you open another subscription just for "the agent's email." Like any good HR question, the real question here is identity, not budget.
A prompt, on the house
A prompt for planning a separate inbox for your agent, paste it into our chat:
1. Remind me: this inbox has exactly one owner, the agent, not me.
2. Ask me whether I already have an address that could work as an alias
for an existing inbox, before we open a brand new account from scratch.
3. Suggest how to connect that inbox to yourself through one clear
connection, without touching my personal or business email.
4. At the end, give me a short summary: what the inbox address is,
and who is connected to it.
