Ask HN: How do you manage newsletters?

Wondering if someone has a cool way of managing newsletters.

Essentially trying to efficiently organize : - ecommerce marekting promotions - email newsletters - dev list, etc (if you are an open source contributor) - social notification emails

Some already known ways but would love to have a vote :-

1. seperate email account

2. + option in gmail

3. do nothing just read all

4. Inbox or other email client

5. Other please specify

thanks !!
