Sending Your Wedding Invitation to 300 Guests on WhatsApp: Broadcast Lists, Groups and What Gets You Blocked

Group, broadcast or one to one: what each does

A couple in a WhatsApp forum asked the question most families hit: they had a spreadsheet of about 150 invitees and wanted to send each one the card and a message, from their own number, without trusting a random bulk app. WhatsApp offers three ways to do it, and they behave very differently.

• Group: one shared chat. Everyone sees every other member's number and every reply. Fine for a small cousins' group planning the sangeet; poor for the invitation itself, which then reads like a notice board.
• Broadcast list: one message from you, delivered to each person as a private chat. Replies come back to you individually, and recipients do not see each other. This is the right tool for the invitation.
• One to one: you send each message yourself. Slowest, most personal, and the only option for people who have not saved your number.

How broadcast lists work, and the catch

1. Each list holds up to 256 contacts, according to WhatsApp's help centre. You can make as many lists as you like, so a 600-guest wedding is three lists.
2. Only contacts who have saved your number in their phone receive the message. Others are skipped with no warning on your side. This is the catch that quietly loses guests.
3. Replies arrive as normal private chats with you, so you can answer each person.
4. Lists are made on the phone app; WhatsApp's help centre says they are not available on WhatsApp Web or desktop.
5. WhatsApp has said some people may see a monthly limit on broadcast messages as it rolls out changes, so do not leave a long list to the last day.

Assume older relatives, parents' friends and anyone you rarely message may not have saved your number. Send them one to one, or ask the family member they do know to send it.

A sending plan that splits the work

The person a guest knows should be the person who sends. That solves the saved-number problem, makes the invitation feel personal and spreads the work over several phones. A plan that works for most families:

• Bride's parents: their own relatives and friends, from their phones, in one or two broadcast lists.
• Groom's parents: the same for their side.
• The couple: their friends and colleagues, one list each.
• Elders and VIPs: no broadcast at all. Call or visit, then send one to one. See is it rude to send a wedding invitation on WhatsApp?.
• One shared sheet: name, who sends, sent date, reply. It stops two people sending to the same aunt and nobody sending to the uncle in Pune.

What to put in the broadcast message

Because a broadcast cannot use each person's name automatically, the message needs to read well to everyone on the list. Make the lists by relationship so the wording fits: family, friends, colleagues. Keep it short, put the link on its own line and make sure the link shows a picture before you send.

What gets numbers restricted, and how to avoid it

WhatsApp restricts accounts that look like they are sending bulk or automated messages, and reports from recipients count against you. Business-messaging guides describe the common triggers: sending large numbers of messages to people who have not saved you, using modified apps or automation tools, and many people blocking or reporting your number. A wedding invitation is not spam, but a burst of identical messages from an unofficial tool can look like it.

1. Use the official WhatsApp app and its broadcast lists, not GB WhatsApp, browser extensions or paid blasting tools.
2. Send from numbers your guests know, which keeps blocks and reports near zero.
3. Spread sending over a day or two rather than hundreds of messages in a few minutes.
4. Never add people to a group without asking, and do not message people who ask you to stop.
5. Do not send the invitation as a file that needs installing. With fake invitation scams in the news, guests rightly report anything that looks like one: see fake wedding invitation scams.

After sending: replies, reminders and changes

Replies to a broadcast come back as individual chats, which gets messy at volume. An invitation with its own RSVP keeps the answers in one place, by event, so you are not scrolling through 200 chats to count the mehendi. Use the same broadcast lists later for a reminder a week before and for any change of time or venue, so the people who got the invitation are exactly the people who get the update.
