Hi @MariaDP,
If you have workflows, the most straightforward option would be:
- Create CTA: Create calls-to-action (CTAs)
- Have the CTA point to a plain simple page, e.g. something that just says “Thank you for subscribing”
- Place CTA in email
- Use a contact-based workflow to enroll contacts who click the CTA, then update their communication subscriptions
Without workflows, you would simply create a landing page with a subscription form. The CTA would not subscribe them directly, they would have to submit the form.
Let me know if you have any follow-up questions!
