小白求助，发信写的是否得当···感谢

这段发信内容存在一些小问题，我来帮你指出：

1. "Glad to hear that you're on the Spain market for glasses is very competitive." 这句话的表述有些奇怪，建议改为："We are aware that the glasses market in Spain is highly competitive."

2. "We specialize in this field for several years, with the strength of chopped metal frame and Other frames..." 这句话容易让人误解，建议修改为："We have several years of experience specializing in glasses, with a focus on metal frames and other types of frames."

3. "Should you he any questions, pls do not hesitate to contact me." 这句话中出现了拼写错误，应该是 "Should you have any questions, please do not hesitate to contact me."

4. "FREE SAMPLES will be sent for your evaluation!" 这句话应该改为 "We would be happy to send you free samples for your evaluation!"

希望这些指正对你有帮助！
