To send email campaigns from Swashi, you connect your own mailbox: Gmail, Outlook / Microsoft 365, Brevo, SendGrid or any SMTP server. Open **Email Outreach**, click **Connect account**, choose your provider, enter the details below, then **Verify Account** and **Save Account**. Swashi then warms the new mailbox up automatically before it sends at full pace.

## Before you start

- **A paid plan.** Email Outreach is locked on the Free plan. Starter includes 1 mailbox, Growth 6, Agency 18 and Enterprise 55. Extra Inbox (+1 inbox) and Outreach Pack (+3 inboxes) add more. See current prices on the [pricing page](https://swashi.io/pricing).
- **The mailbox you want to send from.** Every campaign email goes out from an account you own, so replies come back to you.
- **2-factor authentication** turned on, if you use Gmail or Microsoft 365. You need it to create an app password.

## Connect an account

1. Click **Email Outreach** in the sidebar. The page opens on **Outreach Studio**.

   ![Email Outreach highlighted in the Swashi sidebar with the Outreach Studio page open](https://swashi.io/docs/img/ep7-accounts-nav.webp "Open Email Outreach to reach Outreach Studio.")

2. In **Email Sending Accounts**, click **Connect account**. If you have no accounts yet, the card reads "Connect an email account to start sending campaigns."

3. In **Connect Your Email Account**, under **Choose Your Service Provider**, pick your provider. To switch later, click **Click Here to Change Provider**.
4. Fill in the fields for your provider (see the sections below).
5. Click **Verify Account**. When you see "Connection verified! Click Save to add this account.", continue.
6. Click **Save Account**. The mailbox is added to your account list with its warm-up status.

## Gmail (app password)

The window title reads **Connect Your Gmail Account**.

1. In your Google account, turn on 2-factor authentication.
2. Create an **App password**: Google Account → Security → App Passwords.
3. In Swashi, enter **Your Gmail ID** (your Gmail address).
4. Paste the app password into the password field. Use the app password, not your regular Google password.
5. Click **Verify Account**, then **Save Account**.

## Outlook / Microsoft 365

The window title reads **Connect Your Outlook / 365 Account**.

1. For a Microsoft 365 work or school account, turn on 2-factor authentication and generate an app password. The app points you to account.microsoft.com → Security → Advanced security.
2. Enter **Your Email ID** and **Your App Password**.
3. Click **Verify Account**, then **Save Account**.

> **Important:** The app notes that personal Hotmail/Outlook.com accounts can no longer send via SMTP (Microsoft disabled it). Use Gmail, Brevo or SendGrid instead.

## Brevo

The window title reads **Connect Your Brevo Account**.

1. In Brevo, go to **SMTP & API → SMTP** (app.brevo.com/settings/keys/smtp).
2. In Swashi, enter **Sender Email (From)**. This must be a verified Brevo sender.
3. Enter **Brevo SMTP Login**. This is the "Login" shown in Brevo → SMTP & API → SMTP (it looks like xxxx@smtp-brevo.com), not your email address.
4. Enter **Your Brevo SMTP Key**.
5. Click **Verify Account**, then **Save Account**.

> **Note:** If you see an "Unauthorized IP" error, turn off **Authorized IPs** in Brevo. Swashi sends from changing server IPs.

## SendGrid

The window title reads **Connect Your SendGrid Account**.

1. In SendGrid, go to **Settings → API Keys** and create a key. Make sure it has **Mail Send** permission.
2. In Swashi, enter your **Sender Email ID**.
3. Paste the key into **SendGrid API Key**.
4. Click **Verify Account**, then **Save Account**.

> **Note:** SendGrid is a sending-only service. Inbound reply monitoring is not available for this provider, so replies will not reach your [Unified Inbox](https://swashi.io/docs/outreach/unified-inbox).

## Any other provider (SMTP)

The window title reads **Connect Your SMTP Account**. Use this for providers that offer standard SMTP, such as your own domain's mail server.

1. Enter **Your Email ID**.
2. Enter **Your SMTP Host Link**: the SMTP hostname from your mail provider.
3. Enter the **Port**. Common ports are 587 (STARTTLS) or 465 (SSL).
4. Enter **Your Password** for that mailbox.
5. Click **Verify Account**, then **Save Account**.

## After you connect

- **Warm-up starts automatically.** The account card shows "Day N of warmup", the safe number of sends for today and how many were sent. Read [Deliverability and warm-up](https://swashi.io/docs/outreach/deliverability-and-warmup) for the full ramp.
- **Round-Robin rotation.** With more than one account, emails rotate across all active accounts in order (#1 → #2 → #3). Paused accounts are skipped.
- **Pause or resume.** Click **Pause** on any account to remove it from rotation without disconnecting it, and **Resume** to bring it back.
- **Daily send cap.** Each account shows its **Daily send cap**.

> **Tip:** Connect your mailbox early, even before your first campaign is ready. Warm-up counts from the day you connect.

## Troubleshooting

| What you see | What to do |
|---|---|
| Verification fails on Gmail or Microsoft 365 | Check that 2-factor authentication is on and that you pasted an app password, not your normal password. |
| "Unauthorized IP" with Brevo | Turn off Authorized IPs in Brevo, then click Verify Account again. |
| Brevo login rejected | Use the SMTP Login from Brevo's SMTP & API → SMTP page, not your email address. |
| Personal Outlook.com or Hotmail will not connect | Personal Microsoft accounts can no longer send via SMTP. Connect Gmail, Brevo or SendGrid instead. |
| "Connect an email account first" in Email Studio | No sending account is connected yet. Connect one here first. |

## Frequently asked questions

**Do I use my normal Gmail password to connect Gmail?**

No. Turn on 2-factor authentication in your Google account, then create an App password under Google Account → Security → App Passwords, and paste that app password into Swashi.

**Can I connect a personal Outlook.com or Hotmail address?**

The app notes that personal Hotmail/Outlook.com accounts can no longer send via SMTP because Microsoft disabled it. Use Gmail, Brevo or SendGrid instead. Microsoft 365 work or school accounts can connect with an app password.

**Why do I get an Unauthorized IP error with Brevo?**

Swashi sends from changing server IPs. If you see an Unauthorized IP error, turn off Authorized IPs in your Brevo account and verify again.

**Will replies show up if I connect SendGrid?**

No. SendGrid is a sending-only service, so inbound reply monitoring is not available for this provider. Use a mailbox provider such as Gmail if you want replies in your Unified Inbox.

**How many email accounts can I connect?**

It depends on your plan: Starter includes 1 mailbox, Growth 6, Agency 18 and Enterprise 55. The Free plan cannot connect mailboxes. See the pricing page for current plans and add-ons.
