If you have a "newsletter"...
When a new subscriber joins, do you ghost 👻 them until the next newsletter issue?
The "ghost" time could be 2 weeks if it's a bi-monthly newsletter or 4 weeks if it's monthly.
During this time, they would've forgotten about you if you don't put them into a welcome sequence, or at the very least send them a welcome email.
You've already done the hard work of convincing them to sign up, why waste your time and effort you've if you're going to ghost them anyway?
What is your reason for ghosting 👻 them?
