Is there a technical problem with Quickbooks if I can't send an invoice through my email?

Hi there, Molly. Please start by checking your spam or junk folders, as security filters can sometimes misroute automated invoices.

You may also want to verify your email address under the Gear icon in the Sign-in & Security section. It is also better to clear the field and re-enter the address manually to ensure there are no hidden spaces or typos.

If you have other email addresses with different domains, consider sending your invoices to those as well. This can help determine if there is an issue with your current domain.

Please let me know if those steps don't resolve the issue, and we can investigate further.
