What are the some of the approaches one can use to reach eCommerce stores owners?, my emails to them are not being opened or replied to much.
What are you sending them? Most ecomm sees every message you send them - not replying has very little to do with reaching them, it's likely rooted in the message you're sending. Maybe share here and can suggest improvements...
Point out some issue with their store first, provide a solution, then ask/offer what you wanted to
What do your comms look like? Are they short and precise, yet offering something of interest to their needs?
