My clients informed me that they didn’t receive my invoice this week via email. This has never happened previously. I had to send it to all clients via WhatsApp.

A few things could be going on here, including incorrect email addresses or an issue with the recipient's email server. It's worth checking your Invoices list and reviewing the Status column to confirm whether they were sent from QuickBooks Solopreneur (QBSP) or if QuickBooks was unable to deliver them.

If it shows as Undeliverable, review the email addresses saved for each affected client and make sure they're correct before resending the invoices.

You'll also want to ask your clients to check their spam or junk folders, since QuickBooks emails can sometimes get filtered there. If the email is still not found, clear and re-enter your email address in the Settings.

1. From there, select the Company tab,
2. Under Contact info, Edit the Email section.
3. Clear the field and enter the desired address as is, even if it appears correct.
4. Hit Save, then Done.
5. Send yourself a test transaction.

You can use a different email address that has a different domain if you still don't receive the email.

If the issue persists, you'll want to configure your server or have your IT expert update it to accept QBSP email server hostnames and IP addresses so your clients can receive your emails from QuickBooks.

Don't hesitate to reply below if you have further questions. I'll respond to you promptly.
