# Senders Overview

# Senders Overview

## Purpose

Before any campaign can send, SuperSend needs to know *who* is sending and *from where*. This article explains the three-layer model — mailboxes, social accounts, and sender profiles — so you can set up sending infrastructure correctly the first time.

## The Mental Model

Think of it in three layers:

**Layer 1 — Individual mailboxes and social accounts**
These are the actual accounts you connect: Gmail, Outlook, Mission Inbox mailboxes, LinkedIn accounts, Twitter/X accounts. Each one is a single sending identity. You can connect as many as you have. SuperSend calls these "senders."

**Layer 2 — Sender profiles**
A sender profile bundles together mailboxes and social accounts into one named persona. For example: "Curtis @ TeamSuperSend" might have 5 email mailboxes (for email rotation), 1 LinkedIn account, and 1 Twitter account. When a campaign uses this profile, all outreach from that campaign *feels* like it comes from the same person, even if it's rotating across multiple mailboxes.

**Layer 3 — Campaigns**
Campaigns don't connect directly to individual mailboxes — they connect to sender profiles. So when you launch a campaign, you pick which profile(s) it should send from. Multiple campaigns can share the same profile, or each can have their own.

The reason this structure exists: at volume, you want to rotate across many mailboxes to protect deliverability, but you also want recipients to feel like they're hearing from a real person. Sender profiles solve both problems.

## Prerequisites

- Team access in SuperSend.
- Permission to manage senders.

## Setup Order

1. **Add your email mailboxes** — Go to **Senders** → click **Add Sender** → choose **Email Sender**.
2. **Add your LinkedIn account** (if applicable) — **Add Sender** → **LinkedIn Account**.
3. **Add your Twitter/X account** (if applicable) — **Add Sender** → **Twitter/X Account**.
4. **Create a sender profile** — **Senders** → **Sender Profiles** tab → **Create Profile**.
5. **Attach your mailboxes and social accounts** to the profile.
6. **Assign the profile** to a campaign in campaign **Settings** → **Senders**.

## Navigating the Senders Page

Go to **Senders** from the team sidebar. The page has tabs:

- **Sender Profiles** — your named personas used by campaigns
- **Mailboxes** — all individual email mailboxes across your team
- **Domains** — domains purchased or synced through SuperSend
- **Social** — connected LinkedIn and Twitter/X accounts

You will spend most of your time in **Sender Profiles** once initial setup is done.

## Enterprise mailbox rollouts

If IT is connecting many **Microsoft 365** and **Google Workspace** mailboxes at once (for example during a platform migration), use **[Enterprise mailbox connection checklist (Microsoft 365 and Google Workspace)](https://help.supersend.io/en/article/enterprise-mailbox-connection-checklist-microsoft-365-and-google-workspace-1l46317/)**. It summarizes roles, the recommended **Microsoft service account** path and **Google OAuth** path (including **multiple Google OAuth apps on one team**), links to the detailed Gmail, Outlook, and Azure guides, and includes a sign-off checklist—without duplicating those longer articles.

## Expected Result

You have at least one sender profile with active mailboxes attached, and campaigns can be configured to send through it.

## Troubleshooting

- **Issue:** You connected a mailbox but don't see it available in a sender profile.  
  **Fix:** Go to the sender profile detail page → click **Add Mailboxes** to attach it.

- **Issue:** Campaign has no sender profiles assigned.  
  **Fix:** Open campaign **Settings** → **Senders** tab → use the dropdown to add a profile.
