Signedup or a spreadsheet

Most internal lists live in a spreadsheet, and for good reasons. Here is what that costs you, and when it is still the right answer.

The problem is not the spreadsheet

Almost every internal list starts in a spreadsheet, and that is a reasonable place to start. It is free, it is already installed, everybody can read one, and you can have the first version of a list finished before a procurement conversation would have been booked.

The difficulty appears later, and it is structural rather than a matter of discipline. A spreadsheet has an owner. Only the owner can change it. But the person who knows that somebody has moved from the Leeds site to Manchester is the person who moved, and they have no way to tell the file. So the correction has to travel: they mention it to somebody, or they do not, and four months later they are still receiving the Leeds newsletter, or more likely they stopped reading it altogether and nobody knows.

Multiply that by every team move, secondment, name change, leaver and returner in a year and the file is not slightly wrong, it is systematically wrong in one direction: it over-represents the people who have not changed and loses the ones who have.

Side by side

Where the spreadsheet wins, it says so.

What actually changes day to day

The practical difference is where the work sits. With a spreadsheet, every correction is your work: somebody tells you, you find the row, you edit it, you remember to do the same in the other three lists that person is on. With a preference centre the correction is their work, it happens once, and it happens in the place the answer is actually stored.

The second difference is what you can show. If somebody asks why they are receiving something, a spreadsheet can tell you that their address is in a file. It cannot tell you when they agreed, what they were asked at the time, or what the form said when they said yes. That distinction matters the first time somebody complains, and it is not something you can add retrospectively.

The third is reach. A spreadsheet can only hold people who have an email address you already know. A large part of most workforces has neither, which is why every list here comes with a printable poster carrying a code that takes somebody straight to the form.

Questions people ask

Can I import the spreadsheet I already have?

Yes. You map your columns to the questions on your form and import, and the importer will refuse addresses that have previously bounced or unsubscribed so a known-bad address cannot be reintroduced. Imported people are marked as imported rather than confirmed, so you can see at a glance which part of your list has actually agreed to be there.

Can I still export to a spreadsheet?

Yes, at any time and at no charge. Signedup holds the list and keeps it accurate; anything you want to analyse, chart or pivot is better done in a spreadsheet, so the export exists for exactly that. There is no window in which your data is held hostage.

Is this not just a form with a database behind it?

In part, yes. The difference is what happens after the form is submitted: every message you send carries a link back to that person's own record, so the form is not a one-off collection but a permanent way for them to correct what you hold. That is the whole idea, and it is the part a form builder does not do.

What if only a handful of people are on my list?

Then a spreadsheet is probably the right answer and you should keep using it. This is worth paying for when the list is large enough, or changes often enough, that chasing corrections has become a recurring part of your job.

Does it send the newsletter as well?

No, and that is deliberate. You keep sending from whatever you use today. Signedup holds the list, keeps it correct, and gives you the current version whenever you need it.
