Why are receipts not going to customer?

[testprep401]

I have tried multiple times to resend a customer a receipt and it tells me that it has been sent but customer has not received. We thought it may be due to spam setting on her work account's firewall so we then had it sent to her personal email and still no luck. Any advice would be very helpful.

Hello @testprep401, I'm sorry to hear about the trouble. 

Have you tested this with another customer to see if this is an isolated issue? It sounds like you're going through all the steps correctly to re-send a receipt. 

I recommend trying to resend the receipt to an alternate address to see if there is an issue with your customers email blocking these receipts.

Please let me know how it goes! I'll keep an eye out for your reply. 👀
