E-Mail Marketing Expert Needed

I'm in need of a freelancer with expertise in email marketing to help me promote a product or service. Since the target audience is yet unspecified, it will be a plus if you are capable of generating insights about potential demographics. Speedy delivery is not a priority, hence the lack of a set deadline. However, consistent progress and demonstrated skill will be highly valued.

Skills and Experience Required:
- Proven experience in email marketing
- Ability to analyse and determine potential target demographics
- Flexible with schedule and able to work without strict deadlines
