Errand support
Last updated 15 September 2026.
Errand takes the task you have been putting off, does the reading, the comparing and the writing, then stops at the confirm button and hands it back to you.
Why it will not press send
Errand does not send, submit, pay, book or agree to anything, and it has no way to. This is not a setting that could be turned off. The app has five kinds of step, research, compare, draft, prefill and handoff, and none performs an action. There is no outbox and no payment path in it, and the closest it comes to transmitting anything is opening a draft in your own mail app, composed and unsent.
The reason is arithmetic about risk: assistants get roughly one task in three wrong, and on a draft that costs you a re-read while on a booking it costs you a booking.
Why my errand was refused
If a plan came back containing a step that asked to send, book, pay or otherwise act, the whole plan is rejected and you are shown the reason in the app's own words, such as "Refused: a step asked to book". Nothing is dropped so the rest can run: a step like that is evidence that something tried to make the app act, and hiding it would mean the next attempt arrives unseen.
A refused or failed errand is the end of it. There is no way to nudge it and try again, so start a new one.
Why a draft can only be addressed to someone I named
The addresses you type in Anyone it might need to write to are the only ones a draft can be made out to, and Errand will not prepare a message to somebody you did not name. It cannot send anything in any case, but it could otherwise be talked into drafting one to an address you would not have chosen, in the hope that you press send without reading the To line.
What the warning about an odd passage means
Text on a page can be addressed to whatever software is reading it rather than to you. When Errand sees a passage like that it shows it in full, with what it appeared to be trying to do. It was not acted on, because the app cannot act, but a page that does this is worth being careful with. The warning is not a security boundary; what protects you is that there is nothing to execute.
How good is the research
Plans come from a language model working from what it already knows rather than from reading live pages, so an opening time, a fee or an address can be out of date or simply wrong. Check anything factual before you act on it, and treat a draft as a first version.
Pre-fill means values you can select and copy, plus a link to the page they belong on; filling a third party form in directly is not generally possible.
Your task text is sent to Anthropic
This is the part you are least likely to assume, so it is here rather than at the bottom. What you write in the errand goes to a large language model run by Anthropic, which works out the steps and drafts the text, so treat that field as something that leaves us.
Signing in, and what is stored
Signing in is by a code emailed to you, and there is no password. What is kept is your email address, each errand, meaning what you asked for, the plan produced, the drafts prepared and how far it got, and the recipients you have allowed. No card details, no bank connection, and no logins for the places it drafts things for. The app requests no access to your mailbox, calendar, contacts or payment methods.
Deleting your account
From the Account tab. It removes your profile, every errand and your recipient list, immediately and unrecoverably. Anything you already sent yourself is in your own mail app and unaffected.
Privacy
The full policy is at carrierpress.com/errand/privacy, and it names everyone involved: Anthropic, which receives your task text, and Supabase, which hosts the database and sends the sign in codes.
Contact
One person reads that, so a reply may take a few days.
