The Email field is recommended to store a single email address. This field includes data validations, to make sure that actual emails are saved. This means that it searches for an email like structure: email@example.com
If the email is not a valid one, the field in the form will be highlighted in red and it will show the message "This is not a valid email".
Configuring an Email Field
Give your field a name and add a field hint if desired. You can then select the section in which the field will be created or keep the default option.
The field type must be set to 'Email'.
If desired, you can set a default value for all new records. Team members will have the option to override the default value if needed.
Email fields can also be calculated. Just enable the 'Calculated' checkbox and add your custom code in the space available for it.
Enable the 'Required' checkbox if the information for this field is mandatory. It means that if you enable this option, every time a team member creates a new record, they will need to input a date for this field in order to save it.
If you enable the 'Lock After Create' as its name implies, the field will be locked once the new record is saved and the value of the field will not be editable afterward.
Email fields can be set up as 'unique'. This means that the system will prevent duplicates of the Email values from being added to the system. It is recommended to set up the Email as a Unique field if there shouldn't be any duplicates. It helps prevent that team members add the same contact twice.
Once you are done setting your field, click the save button.
Note: All new fields are added at the bottom of the form.
