It is not incorrect. You are simply wrong, as the women who went to Christ's tomb in Mark 16 were NOT sent by Jesus, and in fact were too afraid to tell anyone, and in Luke 24, nobody instructed them to report to the other apostles... they did it on their own. It was in John 20:11_20 where Jesus sent Mary Magdalene alone to tell the other apostles. Mary Is Magdalene was in fact the first one sent by Jesus to testify of His resurrection.
It is very definitely incorrect. You are simply denying what is revealed in the Gospel of Mark. And to properly address your response, here are the Bible facts:
1. Jesus sent NO ONE to the tomb. He had already told everyone that He would rise again. Believing Him would have meant that all the apostles, disciples, and women would meet together and say to each other:
"The Lord will come out of His tomb and meet with us, so let's just wait for Him together. He already told us that He would rise again. And that is the truth".
2. The women showed their love and devotion to Christ by going with spices for His embalming. Obviously they too had not really believed that He would be absent, and assumed that He would remain indefinitely in the sepulchre.
3. Mary was not sent ALONE since the angels asked
all the women to go and report the resurrection to the others. But as seen in John, Mary Magdalene did not go with them but lingered at the tomb and met the risen Lord. Then she joined ALL the other women and reported the matter.
4. It is possible that she related her own encounter, but Mark made is very clear that all the women TESTIFIED of the Resurrection of Christ.
Indeed while they were on their way to the apostles, Christ met them and told them to have the apostles go to Galilee to meet with Him. This would have been before His meeting with Mary!
5. But He did not say that on the day of resurrection He would (a) meet the two disciples on the road to Emmaus, nor that (b) He would meet with all the apostles later on in Jerusalem first, nor (c) that He would come to meet with Thomas after eight day following the day of resurrection . Finally we see that He met them at the Sea of Galilee and fed them a breakfast. After that He continued to meet with them and teach them for forty days before His ascension.
6. If we do not harmonize all the accounts (including what is in Acts 1) we will have some false ideas about the importance of Mary. Indeed she even said that she thought someone had taken Christ's body away, which was not the case for any of the other women or the apostles (who would not believe initially).
