This page is static so formspree.io is used to forward the message to your email. Visitors can send you up to 1,000 emails per month for free. You can set your email in the config.toml file. You then have to confirm your email with formspree and will begin recieving messages after you do so. I recommend only having the contact form on one page, most likely the index.html, because you have to confirm for every URL the contact form is on.
@Wbofeng Contact部分用的是转发邮件实现的，在
config.toml中设置email就可以了关于Formspree可以参考 https://formspree.io/
