Honestly, I wish I had

Honestly, I wish I had more to say. I signed up a few months ago because the designs looked like they might be usable, but I haven’t really done much with it. Maybe it would be valuable to follow up with customers to let them know about new designs that have been placed on the site. Might encourage them to come back.

New designs are released continually at random times every day. For that reason, we can’t send an email to alert about new designs. 
We send weekly newsletter emails to members. In those emails, we include updates on Merch by Amazon, print on demand plaforms, links to new blog posts, and a few designs and other services you may like. Additionally we send occasional special offer emails.
