Track mailto response inside campaign - dynamics-crm

Question

I have created a marketing email to be used in a campaign which has a 'Call to Action' button, a mailto link that drafts a short response for the recipient to easily reply.
I have given the mailto link the same subject as the response email would have if the recipient used their mail client reply button.
When I reply to the email using the client reply button, the response shows up in the campaign response list, but when I reply using the call to action button, then nothing shows up in the response list.
How can I get CRM to track the email response inside the campaign when I am generating the response text via a mailto link?

Answer 1

Probably the regarding field is failed to set in response that’s why it’s failing to show in campaign activities.
Lesson 3: Automate creating campaign responses
For e-mail activities included in your campaign, you can have Microsoft Dynamics CRM Online create the corresponding campaign response records automatically when customers respond to these activities.
For example, from a campaign record, you create a campaign activity and choose e-mail as the channel. Because you created the activity from within the campaign record, the e-mail activity is automatically associated with the marketing campaign. After selecting a marketing list, distribute the activity. Microsoft Dynamics CRM Online then creates individual e-mail activities with the Regarding field pointing to the Subject field of the Campaign Activity form. If the recipient sends an e-mail back to your organization, Microsoft Dynamics CRM Online tries to match the incoming message with the e-mail activities based on information in the e-mail subject line. If Microsoft Dynamics CRM Online finds a match, it creates a corresponding campaign response activity.
