Personal
You should not send professional emails using your personal Yahoo, Gmail, Outlook, AOL, etc. in the FROM address. The emails might:
- not be delivered at all, like on Yahoo,
- or display a warning, like “Be careful with this message” on Gmail which warns about the recipient that he might be spoofed.
It's still possible to use the SMTP with a MTA configuration. See for instance postfix SASL solution but I don't known the repercussion. You should test it.
Dedicated Server
On a dedicated server, you may send:
- via the installation of a MTA
- via the email function of you language
It's free to send with your own host but you need to configure it properly. See How to configure your domain and your server to send and receive email
