# How is lead/account hotness calculated?

What do the fire symbols mean?

Salesflare calculates **lead/account hotness** for you based on:

*   email opens
    
*   email clicks
    
*   website visits
    
*   emails being exchanged
    
*   ...
    

The darker the flame color - yellow for "Hot" or red for "On fire" - the hotter the lead. 🔥

It's time based, focusing only on interactions in the past seven days.

To make use of [open and click tracking](/en/articles/955630-email-tracking-how-does-it-work) in the scoring, make sure you're tracking your emails. Same for the [website tracking](https://intercom.help/salesflare-howto/en/articles/1007216-how-does-the-website-tracking-work).

You can [filter your accounts](https://intercom.help/salesflare-howto/en/articles/1969688-how-do-i-filter-my-data-in-salesflare) by "hotness". And you [get notified live](https://intercom.help/salesflare-howto/en/articles/4811614-what-are-the-notifications-for-in-salesflare) when they become hot.
