The Email Invalid field in Marketo is used to identify records when the lead is created and the email

format is not correct, or when the email is a hard bounce that receives a 5## bounce code signaling

that the email is no longer valid i.e. the email address does not exist1.

A hard bounce is an email that has been returned to the sender because the recipient’s address is

invalid. A hard bounce might occur because the domain name doesn’t exist, the recipient is

unknown, or there is some other permanent error2.

Marketo automatically marks an email invalid when it receives a 5XX bounce code, or if the email

format is not correct when the person is created3. The bounce reasons also populate the Email

Invalid Cause field in Marketo, which can be used to further analyze the types of hard bounces

unique to your email deliverability instance1.

Therefore, the valid reason for a person’s Email Invalid field to be marked as True is when the person

was sent an email that was undeliverable due to nonexistent email address, which is option B.

Dynamic content is a feature of Adobe Marketo Engage that allows you to customize how different

people see a landing page or email based on their segmentation1.

Segmentation is the process of dividing your audience into subgroups based on a smart list rule, such

as industry, location, or behavior1.

You can create different segments and apply them to different program types, such as email, landing

page, or web personalization1.

To use dynamic content, you need to add dynamic content blocks into your landing page or

email. These blocks tell Marketo that you want that piece of content to be different depending on

which person views it1.

For example, you can have a dynamic email subject line that changes based on the recipient’s

industry, or a dynamic landing page headline that changes based on the recipient’s location1.

You can also use snippets, which are reusable pieces of content that can be updated centrally and

applied to multiple assets, such as emails or landing pages2.

Snippets can also be dynamic, meaning that they can change based on the segment of the person

viewing them2.

For example, you can use a snippet as a signature in an email, and have it dynamically change the

sender’s name and title based on the recipient’s location2.

Therefore, the two assets that can be dynamic in Adobe Marketo Engage are emails and landing

pages, as they can both use dynamic content blocks and snippets to personalize the content for

different segments of the audience. Reference: 1: Understanding Dynamic Content | Adobe Marketo

A Smart List is a powerful query tool that allows you to find people in your database who meet

certain criteria based on their attributes and activities1.

To build a Smart List, you need to drag and drop filters from the right panel to the canvas and

configure them with the appropriate operators and values1.

There are some best practices to follow when building a Smart List to optimize performance and

accuracy2. One of them is to include the @ symbol before the domain name when using the Email

Address filter2.

This makes the filter use a faster query that can leverage more effective search algorithms2. For

example, instead of using Email Address contains gmail.com, you should use Email Address is

@gmail.com2.

Using the @ symbol also helps to avoid false positives, such as matching email addresses that have

the domain name as part of the local part2. For example, Email Address contains gmail.com would

match [email protected] as well as [email protected], but Email Address is @gmail.com would only

match the former2.

Therefore, including the @ symbol when using the Email Address filter is considered a best practice

when building a Smart List.

According to the Adobe Marketo Engage documentation, images and files can be added to the

Design Studio and used in various marketing assets1.

While Adobe Marketo Engage accepts all file types for upload, only the major image types (JPG, PNG,

GIF, etc.) will work in the email editor1.

Therefore, the correct answer is

C. .jpg and

D. .gif, as they are both major image types that are

compatible with the email editor. Reference: 1: Add Images and Files to Marketo | Adobe Marketo
