Would you pay for this? (And how much?)

I want to create a productized service where I design and write emails for small businesses.

Specifically businesses that are already making money.

Problem:

Remember to email your customers/clients is hard, and to do it consistently usually requires a discipline approach.

Solution:

I want to offer a productized service, where I handle designing and writing marketing emails for your brand.

You will be responsible for editorial approval.

The price will depend on the length of the emails, plus how frequently you want these emails be created (eg. weekly, bi weekly).

As an add on, I can send them for you and provide a report of the statistics, or you can send them yourself.

Question:

For business owners who already have product market fit and are looking to offload their email marketing process (or at least part of it), is this something you would pay?

And if so, how much is this worth to you?
