Email ​

I use Spark email client connected to various Gmail accounts for my email and I follow some rules when dealing with email. I heavily use labels for indexing important emails and approach emails in GTD way, actioning on every email and keeping my Inbox as close to 0 as possible.

I subscribe to a few newsletters and unsubscribe from anything that brings no value and only adds noise.

gmailctl is a useful tool for setting up email filters. I use Postmark Email Templates often.

MJML, Maizzle & Brail are nice for writing out email templates. Postal is great too. Postmark is great for sending transactional emails fast.

I think cold emails/approaches are great. Here is an example of a good one.

Listmonk is great self-hosted newsletter and mailing list manager. If I ever have a need to self host email server itself, I'd use Mox.

React Email seems nice for sending emails.

Really Good Emails is great overview of nice email designs.

Read edgemail code and walkthrough to understand email servers better.

Notes ​

• All archive does is remove the Inbox label (in Gmail).
  • Gmail doesn't have folders. All your messages are saved in All Mail. Everything else (Inbox, Starred, Drafts, user-labels, etc) are just "views" into a subset of the messages in All Mail. And since there's only one copy of any message, if you delete it from any label, you're deleting the only copy, so it's gone from all of them. If you delete a label you remove that "view", but the messages are still in All Mail.
• Whenever you compose an email, put your ask in the first sentence. Do you want information from them? Do you want them to do something for you? Put it in the first sentence. Then put the explanation and details in the rest of the email.
• If you know someone is very busy, occupied, focused on other things, the best way to get a chance at a piece of their time is with a very short email, not a very long one.
• The only two laws for writing any email: 1. Be Valuable 2. Be Interesting
• After meetings, its great to send a list of actionable items for all those involved as a summary.
• If you want to avoid 95% of promo spam in your inbox, just set up a Gmail filter that moves any email with the word "Unsubscribe" into a separate folder.
• Don't have a tough conversation over email. No matter how tempting it may be.
