Stay in Touch Feature

Stay in Touch Feature

I am unable to determine if ZOHO does or does NOT support the stay in touch feature, allowing to send an email to leads and contacts with a link enabling them to update their own information. 

Can someone tell me if this feature exists? If not could someone tell me if this could be developed through API? and if so does any one know a good API pro. 

Many thanks for any information, lead, hint, clue leading to clarifying this important feature for a CRM platform
