Instagram DM Script for a WhatsApp Community Invite

A WhatsApp community invite should read like a doorman, not a billboard: what the group is for, how often you post, the one rule you enforce, and the link. People join groups whose purpose they understand and leave groups that surprise them. Viralyze sends the invite DM the moment someone comments JOIN, and because the join link is a smart link, you can see how many of the commenters actually tapped it.

The WhatsApp community invite DM script

Automatic DM on keyword JOIN:

"Hi! You commented JOIN. The Weekend Traders community on WhatsApp is where I post my Friday watchlist, a Sunday market recap, and answer questions during the week. One rule: no promotions or tips from members, this is an education group, not a calls group. Join here: [smart link]. Mute it if you like; the Friday post is pinned."

Hinglish version (sent automatically to Hinglish commenters):

"Hey! JOIN comment mil gaya. Weekend Traders WhatsApp community mein Friday watchlist aur Sunday recap milta hai. Promotions allowed nahi hain. Join karo: [smart link]."

The "mute it if you like" line sounds small but reduces the number of people who join and then leave the same day.

Why state the posting frequency?

Because the fear with any WhatsApp group is 200 notifications a day. Saying "Friday and Sunday" tells the person exactly what they are signing up for. If you post daily, say so, and say what time.

Setting the rule in the invite means you can point to it when you remove someone, and it filters out the people who were only joining to drop their own link.

How do you track who joined from which reel?

Paste the WhatsApp invite link into a smart link in the Viralyze app and attach that to the Auto-DM, not the raw link. Each smart link counts taps, and the per-automation funnel shows comments, matched, delivered and clicked per reel.

If one reel brings 300 comments and 40 taps while another brings 80 comments and 60 taps, the second reel attracted the right people. Make more of that one.

Step-by-step setup

1. Create a smart link in Viralyze pointing to the WhatsApp community invite. 2. Create an Auto-DM automation with the "comments on any post" trigger and keywords JOIN, "group link", "add me". 3. Paste the DM script and attach the smart link. 4. Turn on the follow-gate if you want the community limited to followers. 5. Test with the live tester, then switch it on.

Using "any post" means every reel that mentions the community feeds the same automation, and you only maintain one script.

What about the Inbox and the 24-hour window?

Some people reply to the DM instead of tapping the link, usually with "what is this group about?". Those replies sit in the Inbox with the original comment beside them. Answer inside Instagram's 24-hour window and send the link again.

Every commenter becomes a contact with the automation as a source tag, so if you later open a paid tier of the community, you already have a list of people who asked to join the free one.

Frequently asked questions

**Can I use a WhatsApp channel link instead of a group?** Yes. Any link works in the smart link, so channels, groups and communities are all fine.

**What if the invite link changes?** Edit the smart link target in the Viralyze app. The DM and the automation stay as they are.

**Can the DM go out from a story too?** Yes. Add a story-reply trigger with the same keyword so "JOIN" replies to a story get the same invite.
