Mailchimp List Cleanup & Campaign Setup

I need an experienced email marketer to clean my Mailchimp subscriber list by removing non-subscribers such as those who have unsubscribed or have bounced emails. This will help reduce my billing slab.

Additionally, I need two email campaigns per month. The campaigns will primarily be newsletters and promotional offers.

Ideal Skills and Experience:
- Proficiency in Mailchimp
- Experience in email marketing
- Detail-oriented for list management
- Ability to create engaging newsletters and promotional content
- Affordable for a long-term relationship
