Bundle the people your group actually needs into a pack and share one link. Everyone gets everyone — with photos, and without the duplicates.
It holds a set of contacts someone chose to share with you. Opening it only shows you who is in it — nothing is written to your phone until you tap the button, and you can see every name first.
A team, a class, a wedding party, a group of vendors. The people who need each other's numbers are almost never already in each other's phones.
Pick people from your address book and send them together. Names, numbers, emails, addresses and photos all travel with the pack.
Recipients open the link and see exactly who is in the pack before anything is saved. No account, no sign-up — not for them, and not for you.
Delete a pack and its link stops working. Anyone already added keeps their contacts; nobody new can open it.
