The Toffees are propping up the standings, while the Hammers are hovering above the relegation spot on goals scored.
Match preview
Everton experienced a disappointing start to the season, losing their opening two league matches against Brighton & Hove Albion and Manchester United.
They then played out a 1-1 draw in their Women's League Cup clash against Newcastle United, before they won the subsequent penalty shootout to clinch the bonus point.
The Toffees may still be winless, but they would have taken confidence from last Sunday's goalless draw against Arsenal at the Emirates Stadium.
They produced a strong defensive display to claim their first clean sheet of the season, although the result ensured they are still the only side to score in the WSL this term.
Everton will hope to discover a cutting edge in Sunday's meeting with West Ham as they go in search of a fourth consecutive head-to-head victory.
West Ham are now winless in 12 WSL matches after taking just one point from their first three league games of the 2024-25 season.
The Hammers fell to a heavy 3-0 defeat in their WSL opener against Manchester United, before they scored late on to salvage a 1-1 draw from their home clash with Liverpool.
They went on to showcase their top-flight quality in a dominant 6-1 win over second-tier Portsmouth in their first group game of the Women's Super League.
However, West Ham were unable to build upon that result in their recent outing against potential WSL title contenders, with Lauren Hemp and Mary Fowler grabbing a goal apiece to condemn the Hammers to a 2-0 defeat, representing their sixth loss in the last seven away league games.
West Ham's hopes of claiming their second away league win of 2024 will be tempered by the fact they have not beaten Everton in an away match since October 2018.
