It is not a best practice to send out cold emails from your own primary domain. Cold email experts set up separate domains and email addresses for the following reasons:
There is a chance that leads will report you as spam, which will worsen your domain's reputation and thus possibly cause more emails to end up in the spam box.
If you let Luna set up your email infrastructure automatically, you are assured of perfect email deliverability. Luna automatically sets up your SPF, DKIM, and DMARC record, which are considered crucial for avoiding the spam box. We have seen that 97% of our users have not set this up properly themselves.
If you want to start sending out emails on a larger scale, you have to buy multiple domains and email addresses anyway to avoid ending up in the spam box. But don't worry; Luna automatically sets these up for you in the premium plan (you can choose the domains and email addresses here).
The lead/receiver usually does not see your email address when the email arrives, instead they see your name.
