How to create an archive of your sent campaigns?
You can use the web versions of your campaigns to create an archive of the previous issues of your newsletters.
To set up your archive, create a grid or list of all the previous campaigns titles (or images) on your website and hyperlink them with the URLs of the web versions.
If you don't have a website yet, you may want to use a one-page site creator such as Carrd. EmailOctopus has a direct integration with Carrd, so you can also use it as your landing page to collect subscribers. Below you can see an example of how you can hyperlink the campaigns titles there.
