• 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format is not correct, or when the email is a hard bounce that receives a 5## bounce code signaling that the email is no longer valid i.e. the email address does not exist1.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.

• A Smart Campaign is a workflow that automates actions based on triggers and filters.
• There are two types of Smart Campaigns: trigger and batch.
• A trigger Smart Campaign listens for a specific activity or change in data and then executes actions for each person who meets the criteria. For example, a trigger Smart Campaign can send an email to a person who fills out a form on a landing page.
• A batch Smart Campaign processes all qualified people at once, regardless of when they performed the activity or changed the data. For example, a batch Smart Campaign can update the lead status of all people who attended a webinar.
• Therefore, the type of Smart Campaign that processes all qualified people at once is a batch Smart Campaign. References: : What is a Smart Campaign? : Trigger Smart Campaign Example : Batch Smart Campaign Example

• A single opt-in process is when a person fills out a form and is automatically added to the mailing list without any further confirmation1.
• An automatic opt-in process is when a person is added to the mailing list without their explicit consent, such as by pre-checking a box or by purchasing a product2.
• A double opt-in process is when a person fills out a form and is then sent an email that requires a click to confirm the opt-in. This ensures that the person has given their permission and has a valid email address13.
• Therefore, the correct answer is C. Double opt-in, as it matches the description of the scenario given in the question. References:
