Having a problem with emails not going to customers. QB support was no help, on the phone over an hour, someone was to call back but did not. Need this resolved ASAP

I completely understand your frustration, @solutions4leather. This is certainly not the level of service we aim to provide. I appreciate your efforts to troubleshoot the issue independently and the time you've spent contacting our support.

Before we get started, I just want to verify whether the invoices and estimates were successfully sent to your customers, or if there was an error when sending emails to your customer. Could you confirm this for me?

Since your customers haven't received emails, please ask them to check their junk mail and spam folders. If the email is still not found, let's clear the email field and re-enter the email addresses.

To do so, here's how:

1. Go to the Gear icon, select Account and Settings under Your Company column.
2. Navigate to Company section, then click the Pencil icon in the Contact info field.
3. Clear the Company email field and re-enter the desired address exactly as it should be, even if it looks correct initially.
4. Select Save, then Done.

Next, perform a test transaction by sending an email to yourself. If you still do not receive the email, consider using an alternate email address with a different domain. For example, if your initial attempt was with a Gmail address, try using a Hotmail or Yahoo address instead.
