When I send invoice, no emails are going out

I have the same issue . Everything was ok last week.

We are having the same issue.  emails were working yesterday and our re-occuring sales receipts went out this morning t 4:34am.  Nothing since then.  Please advise!

Hello, All.

Some emails sent from QuickBooks are being blocked by the customer's external server or service provider. We're aware of this issue and right now our engineers are working to provide a fix for this matter.

While they are working on the fix, let's perform the suggested troubleshooting steps. To start, have them check their spam or junk folder. You can refresh your email setup if the invoice is still missing.

Here's how:

1. Go to the Gear icon at the top.
2. Select Account and Settings.
3. Go to the Company on the left panel.
4. Click the Pencil icon for Contact info.
5. Clear the Company email address field and enter the desired address, even if it shows as the correct one. Make sure not to use any extra characters or spaces before, within, or after the address, you enter.
6. Click Save and Done.

If the issue persists, you can save the invoice as a PDF file and then send it through your business or another email address. By selecting the Save and share link, you can also send your customer a link to their invoice by SMS or a messaging platform. Next, copy the link and paste it into your SMS or messaging app.

I also advise contacting our QuickBooks Online Support so they can add you to the list of individuals that are affected. You will then be notified through email if the problem has been fixed in this way.

For future reference, I've added this article to guide you in recording payments: Record invoice payments in QuickBooks Online.
