Your invoice is sent to the email address you used when providing your payment information. It comes from invoice@meaningsphere.com. Sometimes these emails get sent to spam/junk, or they could wind up in a different folder, such as your promotional folder.
If your invoice isn’t showing up in any of those places, then we can re-send it to your email address. Go to support.meaningsphere.com and click the purple Support button in the bottom right of the screen to submit the request.
