# What is a variable?

Hello **{firstname}**!

Here, **{firstname}** is a variable. It is a tag that you can insert into your emails and contracts. The variable's name is enclosed in curly braces {}.

With variables, you have the ability to write email and contract templates that will be the same for all your clients but will be **personalized using variables**.

Examples:
* At the beginning of your emails, you can write "Hello {firstname}" and the {firstname} variable will be automatically replaced by your client's first name.
* In your contract, you can include the {session_date} variable, and the shooting date will be automatically added to your contract without having to do it manually.

||| Fotostudio provides you with a set of variables. For more information, see the article [What variables are available?](/en/article/1cuvrrp).

You can access the list of available variables when editing text by using the `Variables` button (label icon 🏷) in the text editor. If you select a variable, it will automatically be placed where your cursor is.
