The build is the same on all four. What changes is the approval process, the pacing and how much of the account behaviour I have to protect.
Telegram
The deepest of the four. No approval process and no rate ceiling worth worrying about. Most broker and prop desks live here, which is why most deployments start here.
Bots
A proper bot account, so it survives a phone being lost.
Groups
Sits in a group and answers only when addressed.
DMs
Full conversations from a real account when a bot would feel wrong.
Media
Reads the screenshots and documents people send it.
WhatsApp
Business API or multi-device, depending on volume and how much you want to spend on templates. Account behaviour matters more here than anywhere else, so pacing is deliberately conservative.
Business API
Official, template based, survives scale.
Multi-device
Cheaper and faster to start, needs careful pacing.
Pacing
Randomised gaps in minutes. Bursts get numbers banned.
One session
It never reconnects just to send. That churn is what flags an account.
Instagram
DMs, story replies and comments through the Graph API. Meta App Review and Business Verification are already cleared on my side, so you are not waiting weeks on a Meta decision.
DMs
The main surface. Full conversations.
Story replies
Usually the warmest lead you get all week.
Comments
Answers in public, continues in private.
Cleared
App Review and Business Verification already done.
Discord
Servers and direct messages. Underrated for prop firms and trading communities, where the whole audience already lives in one server and nobody is reading email.
Servers
Answers in channels and keeps its replies in threads.
DMs
Moves a qualified conversation out of public.
Roles
It can gate what it says by role.
Events
Reacts to joins, so a new member is greeted by something that sells.
