cPanel includes a mailing list feature. It has real limits.
WHAT IT DOES
Creates a list address that distributes to subscribers, with subscription management and archives.
WHERE IT IS
cPanel > Mailing Lists.
WHAT IT IS SUITABLE FOR
A small internal list, such as a team announcement address A community list with modest membership
WHAT IT IS NOT SUITABLE FOR
Marketing newsletters. Shared hosting sending limits will interrupt a campaign partway through, there is no bounce handling, no engagement reporting, and one complaint-heavy send damages the sending reputation of every account on the server.
USE A PROPER PROVIDER INSTEAD
SendGrid, Brevo, Mailgun or a marketing platform. Most have free tiers adequate for a small list, and they handle unsubscribes, bounces and deliverability properly.
IF YOU DO USE THE BUILT-IN LIST
Keep it small, keep it to people who asked to be on it, and watch the sending limits.
Set moderation so a subscriber cannot post to everyone unchecked.
