I'd like to follow up on how we can cooperate in the content matter.
I'm open to discuss the details here, alternatively, we can set up a call here.
P.S. If you're not the right person to this matter, I'd be happy to know the right contact to talk to.
- Made a quick reminder of the previous email (discuss content cooperation).
- Added a CTA offering to convenient options to proceed with conversation (via email or phone call).
- Asked for the decision-maker’s contact information, in case the prospect Katia is reaching out to is not a relevant one.
