Tell me where you're up to.
Most email lists treat everyone the same. Which is how a woman at eight weeks ends up reading about the fourth trimester, and a woman with a four-month-old gets sent workshop dates she has no use for.
Two questions fixes most of that.
What happens next. One email a week, Tuesday mornings. One thing explained properly each time, usually something a woman asked me in clinic that week and couldn't get a straight answer on anywhere else.
If you've just clicked through from an email of mine, you're already staying on the list. This part is only so I can send you better things.
You can change any of this later, or leave altogether, and both are completely fine.
