## Setting Up Email

Navigate to **Settings → Channels** and click **Configure** next to Email.

### Step 1: Sender Information

Configure your sender details:

| Field            | Description         | Example                                       |
| ---------------- | ------------------- | --------------------------------------------- |
| **Sender Name**  | Name shown in inbox | "Sarah from Acme"                             |
| **Sender Email** | From address        | "[hello@acme.com](mailto:hello@acme.com)"     |
| **Reply-To**     | Where replies go    | "[support@acme.com](mailto:support@acme.com)" |

<Tip>
  Use a recognizable sender name. "Sarah from Acme" performs better than generic "Acme Marketing Team".
</Tip>

### Step 2: Domain Verification

Verify your sending domain to improve deliverability:

<Steps>
  <Step title="Add Your Domain">
    Enter your sending domain (e.g., acme.com)
  </Step>

  <Step title="Get DNS Records">
    RevBridge provides DNS records to add
  </Step>

  <Step title="Add Records to DNS">
    Add the records via your domain registrar
  </Step>

  <Step title="Verify">
    Click Verify and wait for confirmation
  </Step>
</Steps>

### Required DNS Records

| Record Type | Purpose                                  |
| ----------- | ---------------------------------------- |
| **SPF**     | Authorizes sending servers               |
| **DKIM**    | Cryptographic signature for authenticity |
| **DMARC**   | Policy for handling failures             |
| **MX**      | Return path for bounces                  |

<Accordion title="Example DNS Records">
  ```
  # SPF Record (TXT)
  v=spf1 include:_spf.revbridge.ai ~all

  # DKIM Record (TXT)
  revbridge._domainkey.yourdomain.com
  v=DKIM1; k=rsa; p=MIGfMA0GCSqG...

  # DMARC Record (TXT)
  _dmarc.yourdomain.com
  v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com
  ```
</Accordion>

  DNS changes can take up to 48 hours to propagate. Plan ahead when setting up email.

## Email Best Practices

### Subject Lines

| Do                          | Don't                    |
| --------------------------- | ------------------------ |
| Keep under 50 characters    | Write long subject lines |
| Create curiosity or urgency | Use ALL CAPS             |
| Personalize when possible   | Use spam trigger words   |
| A/B test variations         | Mislead about content    |

**Examples**:

* ✅ "Sarah, your cart is waiting"
* ✅ "24 hours left: 20% off everything"
* ❌ "FREE!!! CLICK NOW!!! LIMITED TIME!!!"

### Preview Text

The preview text appears after the subject in many email clients:

* Keep it under 100 characters
* Complement (don't repeat) the subject line
* Include a call to action

### Email Design

**Above the fold** (visible without scrolling):

* Logo
* Main headline
* Primary CTA
* Key message

**Structure**:

* Single column for mobile compatibility
* Clear visual hierarchy
* Adequate white space
* Scannable content with headers

### Images

| Guideline                   | Reason                        |
| --------------------------- | ----------------------------- |
| Include alt text            | Images may be blocked         |
| Optimize file size          | Faster loading                |
| Use hosted images           | Better tracking               |
| Don't rely solely on images | Some clients block by default |

### Call to Action

* Make buttons large and tappable (44px minimum)
* Use contrasting colors
* Action-oriented text ("Shop Now" not "Click Here")
* One primary CTA per email

## Deliverability

### Reputation Management

Your sender reputation affects inbox placement:

| Factor          | Impact                  |
| --------------- | ----------------------- |
| Bounce rate     | Keep under 2%           |
| Spam complaints | Keep under 0.1%         |
| Engagement      | Higher is better        |
| Authentication  | SPF/DKIM/DMARC required |

### Avoiding Spam Filters

* Maintain clean lists (remove invalid addresses)
* Honor unsubscribes immediately
* Avoid spam trigger words
* Balance text and images
* Include physical address
* Use reputable sending infrastructure

### Warming Up

For new domains or IPs:

<Steps>
  <Step title="Start Small">
    Begin with your most engaged subscribers (100-500/day)
  </Step>

  <Step title="Gradually Increase">
    Double volume every few days
  </Step>

  <Step title="Monitor Metrics">
    Watch bounce and complaint rates closely
  </Step>

  <Step title="Adjust as Needed">
    Slow down if metrics decline
  </Step>
</Steps>

## Analytics

Track email performance in the Analytics section:

| Metric           | What It Measures      |
| ---------------- | --------------------- |
| **Sent**         | Emails dispatched     |
| **Delivered**    | Reached inbox/spam    |
| **Bounced**      | Failed delivery       |
| **Opened**       | Unique opens          |
| **Clicked**      | Unique link clicks    |
| **Unsubscribed** | Opt-outs              |
| **Converted**    | Completed goal action |
