# Sending campaigns

This section covers everything from "I just connected a number — can I send to my 50,000 contacts?" (answer: no, here's why) to "my campaign got cancelled by the safety check, how do I recover?" (answer: Resume Skipped with the Conservative drip).

Read these in order if you're new. Skip to the one you need if you've been through this once already.

## The four things that determine whether your campaign succeeds

1. **Your messaging-limit tier** — how many unique recipients Meta lets you reach in any 24-hour window. Starts at 250, climbs to 1K / 10K / 100K / unlimited as you prove you're a healthy sender. Full mechanics: [**Messaging tiers & limits**](/vibot/sending/messaging-tiers).
2. **Your quality rating** — Meta's green/yellow/red signal based on user blocks and spam reports. RED + sustained = your tier drops. Recovery is slow (7-day rolling window). Full mechanics: [**Quality rating**](/vibot/sending/quality-rating).
3. **How you ramp up a new number** — a brand-new connected number that immediately sends 3,000 messages will get spam-flagged regardless of how clean the contacts are. The fix is to warm up gradually. Full mechanics: [**Warm up a new number**](/vibot/sending/warm-up-new-number).
4. **Your contact list quality** — dead numbers, opted-out recipients, recipients globally blocked for marketing frequency. Vibot's campaign **preflight** flags most of these for you automatically. Full mechanics: [**Send a campaign**](/vibot/sending/send-campaign).

## The honest summary for new senders

<Callout type="warning">
**Three rules every new sender needs to internalise:**

1. **You cannot blast 3,000–4,000 messages on a brand-new number.** Even if Vibot lets you click Launch and your wallet has the balance, Meta will silently pre-block 30–50% of them within the first hour. Your number's quality rating will drop, your tier will reset its scaling timer, and recipients will see nothing.
2. **Your daily ceiling on day 1 is 250 unique recipients.** That's Meta's `TIER_250` default. You can send to the same 250 people multiple times (with templates outside the 24h window, they re-bill), but the *unique-recipient* count is the cap.
3. **Speed isn't the gating factor — proof is.** Meta upgrades you to 1,000/day after Business Verification AND a stretch of HIGH quality. They upgrade you to 10K after sustained HIGH quality at the 1K level. It's a ladder, and trying to skip rungs gets you flagged.

## What Vibot does to keep you safe

Vibot is not a "blast as fast as possible" tool. It's specifically built to keep your number healthy and your tier climbing. Six safety layers run on every campaign:

| Layer | What it does |
|---|---|
| **Preflight check** | Before launch — counts dead numbers, opt-outs, duplicates, dedupes, and length-overflow rows. Surfaces tier label. Reds = block; ambers = warn + checkbox; greens = ready. |
| **First-send warning** | First campaign on a new number → modal recommends Conservative drip. First time using a specific template → same modal. |
| **Send-rate cap** | Per-tenant `msgs/min` ceiling. Settable by Virtuo admin during your first 30 days; can be made permanent on request. |
| **Canary cohort** | First 10 recipients of every campaign are sent as a canary. 60 seconds later Vibot checks for spam-block errors (131049). If ≥5% of the cohort failed, the entire campaign auto-cancels. |
| **15% per-batch hard halt** | Inside a single 50-message batch, if 15%+ fail with spam-block codes, the worker halts the whole campaign. |
| **Drip strategies (Resume Skipped)** | After a halt, recover the un-sent recipients with Conservative / Moderate paced sends instead of re-blasting. |

You won't notice most of this — it runs in the background and only surfaces if something is wrong.
