How to send a mail on create of record stating that the record is created..

Hi Developers,

Here comes with a new scenario on sending a mail on create of record stating that the record is created.For example I'm  taking an example of on creation of contact mail should send by stating the record is created.the code snippet is as follows:


Explanation : As per sending mail we need to have a From address,To address,Subject ,Body
so first we need to get the from and to address and the we need to crete them accordingly with activity party then by using the system entity email we can send the mail to created record.
please make a note that the post operation used in plugin registration tool.
Hope you understood.

 As per the example
From - User
To - contact record
