Final answer:
A suppressed contact can opt back in by using a re-subscribe link or contacting the organization, respecting all opt-in procedures and relevant laws.
Step-by-step explanation:
Yes, a suppressed contact can opt back in. In the context of email marketing and customer data management, when a contact is suppressed, it means that they are currently opted out of receiving marketing communications. However, they have the right to change their status and opt back in if they choose to do so. This can typically be done by the contact itself, either by clicking a re-subscribe link provided in a previously sent email or by directly contacting the organization to express their desire to receive communications again. It is vital to respect the customer's preference and ensure all opt-in procedures comply with applicable laws and regulations, such as GDPR or CAN-SPAM Act.
