It was Mary Magdalene, and Joanna, and Mary [the mother] of James, and other [women that were] with them, which told these things unto the apostles.
Note 5 at Lu 24:10: Luke made special mention that Mary Magdalene was one of these women who brought the disciples word of the resurrection. As discussed in note 1 at Joh 20:1 and note 5 at Mr 16:8, Mary Magdalene was not actually present with these other women during this instance when they saw the two angels and heard their announcement. She had already departed and brought Peter and John back to the tomb.
Mary Magdalene then lingered behind at the sepulcher (Joh 20:11) and became the first person to whom the resurrected Lord appeared. After seeing the risen Lord, she then returned to the eleven and gave the first personal testimony of seeing Jesus.
Therefore, she did tell the disciples of the resurrection, as the other women did, but not at the same time. Luke did not go into as much detail as John and simply listed all these women together as heralds of this news.
Note 6 at Lu 24:10: Joanna was the wife of Chuza, a household manager for Herod Antipas (Lu 8:3). She was apparently delivered from evil spirits or cured from infirmities by the Lord (Lu 8:2-3). In gratitude, she provided materially for the Lord's ministry from her private belongings (Lu 8:3). It was Joanna, along with the other women, who reported to the apostles the truth concerning the resurrection (Lu 24:1-11).
