Error sending invoice email - Anyone else?

Topic summary

Invoice emails are failing to send on multiple “terms” orders (orders with payment terms). Using Send Invoice → Review Invoice spins briefly, then shows “Error Sending Email” with no detail.

An existing Shopify Flow automation (Shopify’s workflow tool) that emails a copy of the invoice to an AP contact also started failing on the same orders. The Flow run returns a transient “500 internal server error” (a server-side failure).

Screenshots attached show the generic email error and the Flow error message.

The poster is asking if others are experiencing invoice/email issues and for any insight into the cause. No fixes, workarounds, or official responses are reported. Status: unresolved and likely ongoing; key questions remain about whether this is a platform-wide outage or a configuration-specific issue.

We’re getting this error on multiple orders now, when trying to send an invoice to our customer. Both are terms orders. We try to send invoice to customer (or anyone) via the Send Invoice button, we then press “Review Invoice” and it spins for a few secs and then at the bottom we see. “Error Sending Email”

No details about why it can’t send.

On the same order, we have a Flow that is set up to send a copy of invoice to an additional AP contact at the company. That has worked fine in the past, but today on one of these orders where we’re getting the mystery error message above, the Flow is also failing with a transient 500 internal server error

Anyone else experiencing invoice/email related issues? Any idea what’s going on here? This is a problem

Hi @bpaulette ,

Try to export the invoice as a PDF and email it directly to the customers here to make sure they get it. Look for any formatting or invisible characters in the customer emails that could cause errors. Send the invoice from a different browser or make an invoice draft manually to work around the spinning error.
