Help with calling companies

Hello

My name is Angela and I'm a nutritionist and I need to get more leads into businesses. I have a list of 26 businesses which I have emailed already and know they have opened the emails.

I have another list of around 600 contacts but this will be cold calling. I can email first but would not know the open rate will be as I can not add these address in mailchimp.

I offer Nutrition Wellbeing to staff doing a Life Style Improvement System. I would like to get meetings with interested companies wanting to offer nutrition wellbeing to their staff.

Please let me know if this is a project you would take.

Warm Regards
Angela
