1

Create a list of email deliverability factors

Create a list called factors with these exact items: 'Sender Reputation', 'Spam Filters', 'Email Content', 'Recipient Engagement', and 'Authentication'.

Digital Marketing

# Create the list of email deliverability factors
# Your code here

Hint

Use square brackets [] to create a list and separate items with commas.

2

Set a minimum sender reputation score

Create a variable called min_reputation_score and set it to 75 to represent the minimum acceptable sender reputation.

Digital Marketing

factors = ['Sender Reputation', 'Spam Filters', 'Email Content', 'Recipient Engagement', 'Authentication']
# Set the minimum sender reputation score
# Your code here

Hint

Use a simple assignment to create the variable with the number 75.

3

Filter factors based on reputation score

Create a new list called important_factors that includes only 'Sender Reputation' and 'Authentication' from factors, because these are most affected by the reputation score.

Digital Marketing

factors = ['Sender Reputation', 'Spam Filters', 'Email Content', 'Recipient Engagement', 'Authentication']
min_reputation_score = 75
# Create a list of important factors based on reputation score
# Your code here

Hint

Use a list comprehension to select only the factors 'Sender Reputation' and 'Authentication'.

4

Add a final note about monitoring email metrics

Create a variable called final_note and set it to the string 'Always monitor open rates and bounce rates to improve deliverability.'.

Digital Marketing

factors = ['Sender Reputation', 'Spam Filters', 'Email Content', 'Recipient Engagement', 'Authentication']
min_reputation_score = 75
important_factors = [factor for factor in factors if factor in ['Sender Reputation', 'Authentication']]
# Add the final note about monitoring email metrics
# Your code here

Hint

Assign the exact string to the variable final_note.

B. To increase the number of emails sent per hour

C. To design colorful email templates

D. To collect email addresses from social media

Solution

1. Step 1: Understand the purpose of email deliverability

   Email deliverability focuses on making sure emails arrive where they should, mainly the inbox.

2. Step 2: Differentiate from other email tasks

   Sending many emails or designing templates are important but not the main goal of deliverability.

3. Final Answer:

   To ensure emails reach the recipient's inbox, not the spam folder -> Option A

4. Quick Check:

   Email deliverability = Inbox arrival [OK]

Hint: Deliverability means inbox, not spam [OK]

Common Mistakes:

• Confusing deliverability with email design
• Thinking deliverability means sending more emails
• Mixing deliverability with list building

2. Which of the following is a correct way to authenticate your email domain to improve deliverability?

easy

A. Using SPF, DKIM, and DMARC records

B. Adding colorful images to your email

C. Sending emails without a subject line

D. Using only a plain text email

Solution

1. Step 1: Identify authentication methods

   SPF, DKIM, and DMARC are technical records that prove your emails are from you.

2. Step 2: Recognize unrelated options

   Adding images, no subject, or plain text do not authenticate your domain.

3. Final Answer:

   Using SPF, DKIM, and DMARC records -> Option A

4. Quick Check:

   Authentication = SPF, DKIM, DMARC [OK]

Hint: SPF, DKIM, DMARC authenticate emails [OK]

Common Mistakes:

• Confusing email design with authentication
• Ignoring the need for domain records
• Thinking plain text emails improve authentication

3. Consider this scenario: You send an email campaign with a clean list and proper SPF, DKIM, and DMARC setup. However, many emails still land in spam. What could be a likely reason?

medium

A. You cleaned your email list recently

B. You used SPF and DKIM records correctly

C. Your email content contains spammy words or too many links

D. You sent emails only to active subscribers

Solution

1. Step 1: Analyze the setup

   SPF, DKIM, DMARC and a clean list are good practices that help deliverability.

2. Step 2: Identify content issues

   Spammy words or too many links can trigger spam filters despite good setup.

3. Final Answer:

   Your email content contains spammy words or too many links -> Option C

4. Quick Check:

   Spam content = Spam folder [OK]

Hint: Good setup + bad content = spam folder [OK]

Common Mistakes:

• Assuming technical setup guarantees inbox
• Ignoring content quality
• Believing list cleaning alone fixes spam issues

4. You notice your emails are not reaching inboxes because of a missing SPF record. Which action will fix this issue?

medium

A. Remove all images from your emails

B. Add an SPF record to your domain's DNS settings

C. Send emails from a different email address without SPF

D. Increase the number of recipients per email

Solution

1. Step 1: Identify the problem

   Missing SPF record means email servers can't verify your domain's emails.

2. Step 2: Apply the correct fix

   Adding an SPF record in DNS tells servers your emails are authorized.

3. Final Answer:

   Add an SPF record to your domain's DNS settings -> Option B

4. Quick Check:

   Fix missing SPF = Add SPF record [OK]

Hint: Missing SPF? Add SPF record in DNS [OK]

Common Mistakes:

• Thinking removing images fixes SPF issues
• Switching email address without SPF
• Increasing recipients does not fix SPF

5. You want to improve your email deliverability by cleaning your email list. Which approach best applies this concept?

hard

A. Use only HTML emails with many images

B. Add as many new emails as possible without verification

C. Send the same email repeatedly to all contacts

D. Remove inactive or bounced email addresses regularly

Solution

   Cleaning means removing emails that do not engage or bounce to keep the list healthy.

2. Step 2: Identify best practice

   Removing inactive or bounced addresses reduces spam complaints and improves deliverability.

3. Final Answer:

   Remove inactive or bounced email addresses regularly -> Option D

4. Quick Check:

   Clean list = Remove bad emails [OK]

Hint: Clean list by removing inactive emails [OK]
