You may ask why would we ever need a custom button to open an email activity from a record while we can do it from the social pane! Well, good question, and here is the answer: Users want to do their work with fewer clicks.
Let’s say we want to open the new email activity and load a specific template when a custom button is clicked on an account record.
1. Add the following libraries to the Email form:
NB: It is highly recommended to combine both files in one to avoid JS files loading sequence issues.
2. Open the Email form in edit mode, click Form Properties and add two new parameters “parameter_1” and “parameter_2”.
3. Use the following code on the click event of the custom button.
4. Add this code to the onLoad event of the Email record.
5. When the custom button is clicked on the Account record, an email activity is opened in a new popup window and the template is loaded.
