Can I send to more than one email address at the same time?

Sending good vibes to you, alan-stmc.

I'd be glad to share some information regarding sending one email with more than one email address via QuickBooks Online.

If you're trying to send an invoice with more than one email address, then yes, you can. You can add more than one email by separating them with a comma. See the sample screenshot below.

As always, you can visit our Help articles for QuickBooks Online in case you need tips and related articles in the future.

If you're referring to something else, please let me know. I'll be around to help. Have a good one.
