Corporate Partner advertising in digital newsletters

Hi everyone

I was wondering if anyone who is responsible for partnerships had experience with setting up an advertising space in a digital newsletter for corporate partner advertising?

I am very interested to know the following -

- Is it working?

- Has it impacted the open rate or unsubscribe rate?

- Has it been useful for the Corporate Partner? And how did you measure success?

Any other observations and comments very welcome!

Thanks so much
