Does the search engine take into account links in email messages?

Question

Search Engine Optimization

Such an idea appeared, for example - if my site sends letters to users, and the letters end up in spam, or in a non-existent mailbox, can the search somehow take this into account in the output, or does it have nothing to do with the search?

Answer 1

Of course, this has nothing to do with search.

Answer 2

Solidarity with the above unsubscribed. Has nothing to do with search.
