Mailman

What it does

Mailman is a Gmail plugin that lets you control when and what emails land in your inbox. It offers Do Not Disturb times, delivery slots, blocking of unknown senders and newsletters, and a VIP list for important senders, domains, or keywords. It works with any email client that uses Gmail, including Gmail, Apple Mail, Spark, Mailbird, Polymail, and Superhuman.

Mailman is built for people who want to protect focus time without changing their email client. You set Do Not Disturb windows, choose delivery slots, and let Mailman block senders you have not emailed before, newsletters, and notifications. A daily digest shows what was held back, and you decide whether each sender should get through or stay blocked. The VIP list lets important senders, domains, or keywords bypass filters. The pricing page lists one Standard plan at $8 per month paid annually or $10 paid monthly, and a 21-day free trial is available. The site does not state whether an API or open source code exists, so those remain unknown. A careful user should check that the Gmail dependency fits their setup and that the trial gives enough time to tune filters before paying.
