Levell has represented England at Under-17 level, where she helped the young Lionesses to fourth in the European Championships in 2013, and with the Under-19s.
Having worked her way up the ranks at Everton, she made her debut in the 2015 season, going on to make 16 appearances that campaign.
The arrival of Alex Brooks on loan from Manchester City increased competition between the sticks but Levell continued to be included in the matchday squad throughout 2016 and ended the campaign as number one.
Levell retained that spot for the 2017 Spring Series, playing every game and conceding just seven goals in nine matches as the Blue Girls lifted the trophy.
Lizzie Durack's arrival prior to the start of the 2017/18 WSL 1 campaign saw Levell new competition, but she featured as the Toffees reached the Continental Cup quarter-finals and the last four of the FA Women's Cup, ending the season as the number one in the league as well.
