# Sender accounts
> The LinkedIn, email, and WhatsApp accounts Guhan uses to reach prospects.
Guhan doesn't send messages from a Guhan email or a Guhan LinkedIn account — it sends from **your** accounts. You connect them once, Guhan uses them for you.
## Which senders you can connect
Personal LinkedIn or Sales Navigator. Handles invites, DMs, comments, profile views, reactions.
Standard Google Workspace or Microsoft 365 accounts. Handles outbound + reply threading.
Personal or business WhatsApp. Handles outbound messages + inbound reply capture.
## How to connect one
Go to **Settings → Sender accounts → Connect**. Pick a provider, sign in with that provider, and Guhan handles the OAuth handshake.
Guhan uses [Unipile](https://www.unipile.com) as the underlying provider for LinkedIn / Gmail / Outlook / WhatsApp. Your credentials go through their secure OAuth flow — Guhan never sees your password.
## One account, dual role
Your LinkedIn sender account plays **two roles**:
1. **Sending** — invites, DMs, comments to prospects
2. **Discovery** — searching for prospects, pulling reactor lists off posts
Both count toward the same daily quota. Guhan balances discovery vs. sends automatically — if you're near your daily send cap, discovery slows down to protect sends.
## Daily limits
LinkedIn's published safe caps:
| Action | Default | Adjustable up to |
| ------------- | -------- | ---------------- |
| Invites | 25/day | \~40/day |
| DMs | 30/day | \~50/day |
| Profile views | 30/day | \~500/day |
| Comments | 100/week | 100/week |
| Reactions | 300/week | 500/week |
For email + WhatsApp:
| Provider | Default | Note |
| -------- | ------- | --------------------------------------------------------------- |
| Gmail | 500/day | Well inside Google's provider-side ceiling |
| Outlook | 500/day | Well inside Microsoft's provider-side ceiling |
| WhatsApp | 40/day | Unipile personal-app tier (Unipile's own guidance is 30-50/day) |
You can adjust these per-account in **Settings → Sender accounts → \[account] → Quotas**.
## Warm-up
New sender accounts (\< 30 days old) start at reduced capacity and ramp over time:
* **Day 0–7**: 30% of full pace
* **Day 8–14**: 50%
* **Day 15–21**: 75%
* **Day 22–30**: 90%
* **Day 30+**: 100%
Established accounts (existing LinkedIn history, > 150 connections) skip the warm-up entirely.
## Sending window
Every sender has an active **sending window** — the hours + days of the week when messages actually go out. Default: 10am–6pm Mon–Sat, in the sender's timezone.
Set narrow windows to look more human. Set broader windows to send more per day. Guhan spreads sends randomly within the window.
## Multiple senders on one Outreach Agent
You can attach multiple senders to a single Outreach Agent — Guhan will rotate through them to spread volume. Useful when you have 2-3 LinkedIn accounts (yours + team members') feeding the same campaign.
## What happens if a sender breaks
If your LinkedIn account gets restricted, or you change your Google password, Guhan can't send anymore. You'll see:
* A **banner at the top of the app** — "Your LinkedIn account needs re-authentication"
* **In-flight sequence steps** hold in place until you fix it
* **New enrollments** pause until at least one working sender exists
Click the banner or go to Settings → Sender accounts → **Reauth** to fix.
