Hey there, @fgsales.
Thanks for reaching out to the Community.
Emails sent from QuickBooks Online are sent right away, the customer should receive as a normal as they would if you emailed them outside of the program. If you're having some delayed issues, it could be for the following reasons:
- You recently imported data from QuickBooks Desktop.
- The emails could be going into your customer's junk/spam folder.
- You may need the hostnames and IP addresses added to your outgoing mail servers.
You can review the details outlined in 3 solutions for when customers aren't receiving your emails.
Let me know if you have any questions or concerns. I'm happy to lend a helping hand. As always, feel free to reach out to the Community anytime you need assistance. Take care!
