A customer didn't get my invoice email

1. Check the address. Open the customer and make sure their email is right.
2. Check the invoice's email history under Share with customer. Waiting means sending is paused briefly; it goes out automatically.
3. Ask them to look in spam or junk, and to add your address to their contacts.
4. Send the link instead. Click Copy link on the invoice and send it by text or from your own email. The link always works.

If emails still don't arrive, contact support with the invoice number.
