HuddleCard + Slack
Group cards your team signs, reminded and delivered in Slack
HuddleCard automates birthday and work anniversary cards, plus occasion cards for farewells, promotions, and thank-yous. Connect Slack and your team is imported for you, signing reminders arrive as private DMs, and the finished card lands in the honoree's Slack and email on the day.
The Add to Slack button lives on your Integrations page. You'll be asked to log in or create a free account first; it's free for teams up to 10, no credit card to start.
The problem HuddleCard solves
Group cards are lovely and nobody has time to run them. Someone has to remember the date, chase everyone for messages, and get the card delivered without the honoree finding out. On a busy team that job quietly falls on one person, right up until a birthday slips through.
HuddleCard does that job for you. It tracks birthdays and work anniversaries, opens a card ahead of each one, collects messages from the team (text, photos, GIFs, video, and voice), and delivers the finished card on the day. Ad-hoc occasion cards (farewells, welcomes, promotions) work the same way whenever you create one.
HuddleCard is a web app, and Slack is where your team already is, so the Slack integration handles the people-syncing and the nudging. Signing itself happens on a quick web form reached from the DM link, with nothing to install or learn.
What HuddleCard does in Slack
Your people, imported and kept in sync
Connect your workspace and HuddleCard imports your members: names, emails, and profile pictures. You never type a roster by hand.
A daily sync keeps the list current: new Slack members are added and greeted with a welcome DM, and people who leave the workspace are cleaned up automatically. You can also trigger a sync any time from the Integrations page.
Private signing reminders, right on schedule
About a week before each birthday or work anniversary, teammates get a Slack DM with a link to sign the card. A follow-up nudge goes out later in the week for anyone who hasn't signed, and a tomorrow summary lands the day before with every card happening the next day.
Everything is a private DM, with no public channel posts, so the honoree never sees the card coming. Clicking the link opens a quick web form to write a message and add photos, GIFs, video, or voice.
An app home that catches what you missed
Open HuddleCard from your Slack sidebar and the home tab shows any open birthday and work anniversary cards you can still sign, so a buried DM never means a missed card.
There's also a one-click Team Dashboard button that logs you straight into the HuddleCard portal, no password needed. Company admins get an Admin Dashboard button too.
Delivered on the day, shareable if they want
On the birthday or anniversary, the honoree gets the finished card by both Slack DM and email, so nothing is missed. They open it in the browser, where the card stays open for likes, comments, and late arrivals; the first belated signature triggers a next-morning digest DM.
If the honoree wants to show the card off, they can share it to a Slack channel of their choice. That's their call, never automatic.
Every notification, on a schedule you can predict
When Slack is connected, team members with a Slack account get their notifications there instead of (or alongside) email:
| Notification | When | Where |
|---|---|---|
| Upcoming birthdays & work anniversaries | Weekly (Mondays) | Slack DM, or email if no Slack |
| Signing reminders | Weekly (Fridays) | Slack DM, or email if no Slack |
| Tomorrow summary | Day before each occasion (around noon) | Slack DM, or email if no Slack |
| Birthday card delivery | On the birthday | Both Slack and email |
| Work anniversary card delivery | On the anniversary | Both Slack and email |
| Occasion card to sign | When the card is created | Slack DM |
| Occasion card delivery | At delivery time | Both Slack and email |
| Belated sign digest | Morning after a post-delivery sign | Slack DM, or email if no Slack |
Card deliveries go through both Slack and email so nothing is missed. The full schedule is in the Help Center.
Installing HuddleCard in your workspace
- Create a HuddleCard account. Start free for teams up to 10, no credit card needed.
- Open Settings → Integrations in your admin dashboard. You'll need HuddleCard admin access.
- Click Add to Slack. You'll be redirected to Slack to authorize HuddleCard; you'll need to be a Slack workspace admin.
- You're connected. Slack sends you back to the Integrations page, which now shows your connected workspace, and your members import automatically.
After you connect
Add birthdays and work start dates on the People page, or leave them blank and HuddleCard will ask teammates to confirm their own. Make sure celebrations are turned on from the Celebrations page, and the weekly cycle takes over from there: signing opens a week ahead of each occasion, and cards deliver at 9am on the day, in your company's time zone. The first steps guide walks through it step by step.
You can disconnect Slack at any time from the same Integrations page. Disconnecting keeps all the people that were synced (no data is lost) and everything keeps working over email.
Permissions and privacy
HuddleCard asks Slack for the minimum it needs to do the job above:
- View people in the workspace and their email addresses, to import your team and match them to their cards.
- Send direct messages, for signing reminders, card deliveries, and welcome messages.
- Post to a public channel, only when an honoree chooses to share their delivered card to a channel they pick.
HuddleCard never reads your messages, never posts announcements on its own, and never contacts anyone outside the flows described on this page.
What we collect, how we use it, how long we keep it, and how to request access or deletion are covered in our Privacy Policy. Questions or need a hand? Email info@huddlecard.com and we'll respond within two business days.
Common questions
Do teammates sign the card inside Slack? +
No. Slack delivers the reminder with a sign link, and clicking it opens a quick web form where teammates write their message and add photos, GIFs, video, or voice. The honoree can't see anything until delivery day.
Does HuddleCard post birthday announcements in a channel? +
No. HuddleCard isn't a channel-announcement bot: everything arrives as private DMs so the card stays a surprise. After delivery, the honoree can choose to share their card to a channel. If you want a public channel ping too, see our Slack birthday bot comparison.
Do my teammates need HuddleCard accounts? +
No. Only admins create accounts. Everyone else clicks the link in their DM (or email), signs, and they're done. The app home's Team Dashboard button logs them into the portal with one click when they want to browse.
Can I use HuddleCard without Slack? +
Yes. Slack is optional. Everything works over email and the web portal, and you can add people manually or by spreadsheet import.
What does it cost? +
Free for teams up to 10 people. Pro is from $2.50/active user/month (tiered) after a 30-day trial, and there's a Lite tier for occasion-cards-only teams. On Lite the automated weekly cycle is off: you create each occasion card yourself, and Slack still handles the import, sign-invite DMs, delivery, and sharing. Details in the Help Center.
Free for teams up to 10. Connect Slack from your Integrations page in two clicks.
