My process of writing either website copy or email sequence is a lot different than how most writers are doing it.
Here's how it goes:
1) Research (analyzing competitors, using industry jargon, finding keywords Google will love, "lurking" forums to know all about your ideal customer... and a whole lot of other boring stuff).
2) Writing (don't worry, I won't talk how many times I press "delete" on my keyboard while I'm in this process)
4) Formatting (yup, make the copy even easier for your customers/prospects to read).
5) (Optional) Revisions (if you think we need to add something or rewrite it - give me a 24 hours deadline and I'll do it with no extra charge.
... and the only thing you need to do is to publish it.
You don't have to worry about all those grammar mistakes and copied content that will only hurt your agency.
