The last step to moving your newsletter is to open the new list up for new subscribers. How to do this:
1. Revisit your opt-in messages and autoresponders that are attached to your mailing list, and modify them for the general public.
2. Generate sign-up box code for your website, and replace your existing mailing list sign-up with the new code. Make sure that if you have this linked anywhere else – on your social media pages, your blog, on other websites, etc. – that you replace those as well.
Then, don't forget to keep promoting and publishing that newsletter!
