Straight answers

No. Signedup holds the list and keeps it accurate; you keep sending from Outlook, your intranet, or whatever you use today. Export the current list as a CSV whenever you need it. Replacing your sending tool is a much bigger decision than fixing your list, and this is deliberately only the second one.

No, and they never will. Somebody joins by filling in a form, and changes their details later from a link at the bottom of what you send. There is no password to choose, no password to reset, and nothing to be locked out of. That is what makes people actually correct their own record rather than intending to.

Yes. Somebody proves a record is theirs by opening a single-use link sent to their address, so everybody on the list needs one - a work address, or a personal one if that is what your organisation uses. There is no password and no account to create, but there is always an email. For colleagues who are rarely at a desk, every list also comes with a printable code they can scan from a notice board rather than waiting for a message.

Yes, from a CSV, with a preview of what will happen before anything is written. You can also start empty and let people join, which is slower and produces a list that is easier to defend. Most people do both: import the addresses they are confident about, and share the link for everybody else.

A spreadsheet cannot be corrected by the person whose details are wrong. That is the whole difference. Every other property of a spreadsheet is fine, which is why so many internal lists are one, and why the answer is not a bigger spreadsheet.

Those are built to create, send and measure campaigns across a whole organisation, and they are good at it. They are bought over months, cost tens of thousands a year, and need somebody to own them. This does one part of that job for a department or a network, is bought on a card, and takes about four minutes to set up.

The account becomes read-only rather than locked: you can still see everything and still export it. 60 days later it is deleted, and gone from backups within a further 35 days. The window exists so people can get their data out, so shutting them out of it would defeat the point.

The compliance is yours, and the tooling is ours. Every answer is recorded against the exact version of the form the person saw, so consent is evidenced rather than asserted. Subscribers can export or delete their own record without asking anybody. The data-processing agreement is part of the terms rather than a document to request, and everything is stored in the United Kingdom or the EU. None of that is gated behind a plan.

Nobody outside the organisation that collected them, and inside it only the colleagues given access. The companies that help run the service are named individually on the sub-processors page, with what each one does and where it holds data. Nothing is sold, shared or used to train anything.

Every list has a health panel that counts the records nobody has touched in a year and the ones imported but never opened by the person they describe - which is where leavers collect. Asking that group to check their details sends each of them their own one-time link: the people still there update their answers in a click, and the addresses that no longer exist bounce, which is recorded against the record, suppressed, and stops counting towards your plan. You send your own bulletins from your own tool, so that ask is how an address that has died gets found.

One number decides it: how many people are on your lists, counted once each however many lists they appear on. It starts at £29 a month for up to 2,000 subscribers, and colleagues who administer lists are unlimited on every plan. Above 50,000 subscribers it becomes a conversation. Prices exclude VAT.

30 days, no card, up to 500 subscribers, and it runs with the Department features so you see the version worth paying for. There is no permanently free plan: at the end the account becomes read-only and everything is still yours to export.

About four minutes to a link you can share. There is no implementation project, no data migration to plan and nothing to brief an agency on. The longest part is deciding what to ask, and four questions is usually the right number.
