***

### 3️⃣ Analyzing the result

After sending:

1. Return to the Mail-Tester website
2. Click on **“Then check your score”**
3. The tool will display:

* ✅ Final score (from 0 to 10)
* 🔎 SPF check
* 🔎 DKIM check
* 🔎 DMARC check
* 📄 Message content analysis
* 🚫 Blacklist check

***

### 4️⃣ What does each item mean?

#### 🔐 SPF (Sender Policy Framework)

Validates whether the server that sent the email is authorized by your domain.

If there is an error:

* Check your domain's DNS configuration
* Confirm that SPF includes the SprintHub server

***

#### 🔏 DKIM (DomainKeys Identified Mail)

Adds a digital signature to the email to validate authenticity.

If there is an error:

* Check whether the DKIM key was added correctly in DNS
* Confirm that it is active in SprintHub

***

#### 🛡️ DMARC

Defines protection policies against email spoofing.

If there is an error:

* Set up a DMARC record in DNS
* Use an initial policy such as: `p=none` for monitoring

***

#### ✉️ Message Content

Mail-Tester also analyzes:

* Excessive use of words like “FREE”, “PROMOTION”, “URGENT”
* Many shortened links
* Many images and little text
* Lack of a text version (plain text)
* Too clickbait-y subject

***

### 5️⃣ Best practices to improve your score

✅ Set up SPF, DKIM, and DMARC correctly\
✅ Use your own domain (avoid Gmail/Hotmail for sending)\
✅ Avoid link shorteners\
✅ Use natural language\
✅ Keep a balance between text and images\
✅ Always include an unsubscribe option\
✅ Send to cleaned lists

***

### 🎯 What score is considered ideal?

* 9 to 10 → Excellent
* 8 → Good
* 7 or less → Needs adjustments

Ideally, keep it always above 8 to ensure good deliverability.

***

### 🚀 Extra Tip

Whenever:

* Setting up a new domain
* Changing DNS
* Switching sending server
* Creating an important campaign

Run a test in Mail-Tester before sending to your entire list.
