SUBSCRIBE TO EMAILS & NEWSLETTERS:
In CONTACTS TAB > CONTACT NAME > "Profile" tab, you have a section called "Subscription Settings" where you can subscribe your client or prospect to your newsletter and emails. Depending upon the case, select "Client is subscribed to newsletter" and/or "Client will receive emails" and click on "Save".
Important note for emails: In the case of email subscription, activating the settings in the section above only means that the prospect/client will be eligible for being sent these types of communications. When sending the actual email, you need to select the names of the specific contacts.
SUBSCRIBE TO AUTORESPONDERS:
In the case of autoresponders, below the "Subscription Settings" in the contact's "Profile" tab, there is an "Autoresponders" list with all autoresponders created in the COMMUNICATE module. Check the boxes in front the autoresponders you want the contacts to be subscribed to and click on "Save" to implement the changes. To the right of the autoresponders, you will then see the dates when the contact was subscribed.
In the "Profile" tab of the contact > section "Subscription Settings", choose "Client is NOT subscribed to newsletter" and/or "Client will NOT receive emails" and click on "Save". To the right of the settings, you will see when the client was unsubscribed from newsletters and emails.
As for autoresponders, un-checked the boxes in front of the autoresponders you want the contact to be unsubscribed from and click on "Save".
