I have a list of my ebay customers.
I want to add them all to mailchimp list and send marketing emails with link to my shop.
Should I ask people their permission to send marketing emails? How to do this? And how not to get to spam filters?
Anyone out there ever used a programmer to create a bespoke piece of software to do a specific job?
I need to get a little thing made to help me save a bunch of time but have no idea where to look for the guys who do this stuff.
