The customer says they never got my email
ComputerOpen Emails. Sent shows each message and whether it was delivered or opened; a bounce shows on the invoice or quote itself.
PhoneOpen Emails, then Sent.
Start with the address on the customer's record — a bounce almost always means a typo or a mailbox that no longer exists, and the invoice or quote will say Email bounced. Then check the customer's spam folder; email from a business they have not heard from before lands there more often than it should. Sending from your own domain (Settings → Email settings) helps with that. A customer who marked you as spam cannot be sent a quote or a review request again — that is their decision, not a setting — so call them.
