Everyone means to sign it. Then Thursday happens.

You set the card up in two minutes, paste the link in the channel and get on with your day. By the time it sends, eight people have signed and you have spent the week sending individual reminders to the other twenty. The card was never the hard part. The chasing was.

Why group cards go half-signed

It is almost never that people don't care. It's these three, every time.

The link scrolls away

A busy channel moves on in minutes, and a bare link looks like every other link in the thread. Nobody scrolls back up to click something they cannot see.

The chasing lands on one person

Almost always whoever set it up. It is the part of organising a card that nobody volunteers for, and the part that stops people volunteering next time.

The deadline arrives regardless

The card sends on the day whether the team remembered or not. A leaving card with six names on it says something nobody in the room actually meant.

What changes once it's in Slack

The app does one job: it makes the card visible in the place your team already is, and it takes the reminding off your plate.

The link becomes the card

Paste a card or board link and Slack shows its name, its artwork and how many people have signed so far, with a Sign button beside it. Nobody has to guess what they are clicking.

One button, not twenty messages

Anyone in the channel can press Remind the team. It posts a fresh reminder showing the current signature count, so the chasing is a single press and it is not only yours to press.

It counts down for you

Give the card a send date and the channel gets a reminder 48 hours before it goes, on a weekday morning. You stop having to remember, and you stop having to be the one who asks.

Three steps, about a minute

  1. Add it to your workspace

    Press Add to Slack. If your workspace needs an admin to sign off on apps, Slack raises that request for you.

  2. Paste a card link in your channel

    Any expresswithacard.com card or board link expands into a preview on its own, in public and private channels alike. Most cards are organised in a private channel so the recipient does not see it coming, add the app there as well, with /invite @ExpressWithACard, so it can post the reminders too.

  3. Let it do the chasing

    Press Remind the team whenever you want a nudge, or leave it to remind the channel before the card sends. Either way, it is no longer a job on your list.

What it can see, and what it can't

The short version: it is told when someone posts an expresswithacard.com link, it replaces that link with a preview, and it posts reminders in channels it has been invited to. It asks for three permissions and nothing else.

The three it asks for

links:read
Tells us when someone posts an expresswithacard.com link. It is scoped to that one domain, Slack does not send us anything else.
links:write
Lets us replace that link with the card preview, so the message shows what it is.
chat:write
Lets us post the reminder, and only in channels someone has explicitly invited the app into.

What it never requests

  • Reading your messages or channel history
  • Your member list, or anyone’s email address
  • Files, or anything in your direct messages
  • Slash commands of any kind

Signing happens on the web, on the card itself, so the app never needs to know who anyone in your workspace is. Read the privacy policy for the full detail.

Before you install

Questions people actually ask

Yes. Adding it to your workspace costs nothing and there is no subscription. You only ever pay for the cards themselves, from £2.00 as a one-off. See our pricing page for current rates.

Neither. Signing happens on the web, on the card itself, and anyone with the link can add a message, photo, video or GIF with nothing to install and no sign-up. Colleagues outside your workspace can sign the same card from the same link.

It depends on your workspace settings. Many workspaces let anyone add an app. Some require an admin to approve new apps, in which case pressing Add to Slack sends that request for you rather than failing.

You do not, for the preview — that works in any channel the moment the app is installed in your workspace, private channels included. Reminders are different: Slack only lets an app post in conversations it has been added to. Type /invite @ExpressWithACard in the channel once, or use the channel’s Integrations tab if your workspace restricts who can add apps.

At most once per channel every 24 hours, however the reminder was triggered, the manual button included. Automatic reminders only go to cards with a scheduled send date, 48 hours before they send, on weekday mornings. It is built not to become the bot everyone mutes.

Anyone in the channel, and that is deliberate. The whole point is that chasing stops being one person’s job, so restricting the button to whoever set the card up would defeat it. The 24-hour cooldown is what prevents it being overused.

Yes, both. A board link previews and reminds exactly the same way a card link does.

That is expected, Slack only expands links for apps that were already installed when the link was posted. Add the app, then paste the link again so Slack picks it up.

The preview does. Reminders do not, because Slack does not allow an app to post into a conversation it is not part of. Share cards in a channel if you want the reminders.

Your workspace’s ID and name, the token needed to post reminders, and which cards have been shared in which channels. No message content, no member list and no email addresses, we never ask for the permissions that would let us read any of it.

From your workspace’s app settings, at any time. Removing it revokes our access immediately and stops all reminders. Cards already created carry on working on the web exactly as before.

Let Slack do the chasing

Add it once and every card link your team pastes from then on brings its own reminders.
