Run this list every time, even when you are in a hurry. Especially when you are in a hurry.

## Content

1. The subject line matches what the issue actually delivers.
2. The preview text is written on purpose, not the first line of a footer.
3. Every link opens the right page. Click them, do not just read them.
4. Names are spelled correctly, especially sponsors' and guests'.
5. Dates and days of the week agree with each other.

## Format

1. Read it once on a phone-width screen.
2. Images have alt text, and the issue still makes sense with images turned off.
3. Headings are short enough to fit on one line on a phone.

## Sending

1. You are sending to the right segment: free, paid or everyone.
2. Send a test to yourself and open it in a different email app from the one you write in.

## Afterwards

Keep a note of anything you caught. If the same mistake shows up twice, add it to this list.
