Custom Newsletter Template Design

I'm searching for a creative individual with experience in designing engaging newsletter templates. I'll be sending it through our organisation's email, hence an understanding of basic emailing platforms would be an advantage.

The main content of the newsletters will be news and updates related to our organization.

Key Skills:

Preferred Experience:

- Sample of previously designed newsletters would be appreciated.
