Let’s imagine that you are a developer of a company. And you need a contact form on your site that will allow the sender to select an email recipient. Know how to send email to the selected people. Let’s say that the options are the CEO of the company (ceo@example.com), the sales department (sales@example.com), and the support department (support@example.com).
So hereafter email can deliver to the selected department only.
[select recipient "CEO|ceo@example.com" "Sales|sales@example.com" "Support|support@example.com"]
