No. Links need to be capable of being crawled by search engines to determine which site is linking to which other site, and if the linking site is a good link source or a bad one. Search engines do not (overtly) crawl your inbox for links that we know of.
That said, links in emails do help contribute to SEO in a way; the more organic traffic you get to your site, the higher your site will rank in search engine rankings. Traffic is one of the most important signals to Google and other search engines that yoru site brigs value to users.
