Customers not recieving invoices

I thank you for taking the time to be here and express your concerns in QuickBooks Online (QBO). We are committed to helping you get those invoices sent out.

Yes, that's right.QuickBooks Online sends all emails from Intuit servers using our own default domain, and we cannot change this information. However, you do have the option to use your Gmail account to send invoices to your customers.

Furthermore, when an email does not reach its recipients, it's normally due to an incorrect email address or a temporary issue with the recipient's email server. Since their emails are already accurate and other emails are working except from QuickBooks, I recommend having your customer work with their IT support to configure their server to accept QuickBooks Online mail server host names and IP addresses. Please refer to the Solution 3 section of this article: 3 solutions for when customers aren't receiving your emails.

It is also important to note that some email domains may block @intuit.com communications on their servers. You can share this additional steps to your customer to resolve the issue:

1. Send an email to Intuit's email. This should trigger the email domain to recognize the @intuit domain as a trusted site. After doing this, try your request again.
2. After requesting a new verification code, wait at least 5 minutes to see if the email appears in your inbox.
3. If the email does not appear after 10 minutes, contact your email provider to evaluate the security settings for your email profile.

Hi @office-southheat 

QBO sends all emails from Intuit servers.  It would be infinitely better (not to mention, more professional) if there was an option to send via your own email server.  There is/was an option to go via gmail (but mileage may vary on getting that link to work) & unless you use a gmail address, it doesn't look very professional for invoices to be coming from a different address/domain.

To test the system, add your own address as a CC or BCC for all invoices.  If the CC email is getting to you, the system is working as it should.

The problem lies in the workings (or not) of email.

QB/Intuit's servers probably send out millions of emails a day. Every now & again, some of their addresses get blacklisted by other email servers (either intermediate or end user) - essentially marked as senders of spam. When that happens, most end-users will find the QBO emails in their spam/junk folders. However, many corporate systems will either quarantine the emails or delete them without further checks.

QB/Intuit can/should be constantly monitoring the published blacklists & getting their servers removed. How efficient they are at doing that is a question you can probably answer yourself.

If customers cannot check their spam/junk folders your only viable workaround is download & send the invoices from your own email account (or fwd the cc when you receive it). That will be much more reliable as your customer's email system will probably recognise your address as a contact & be more likely to allow emails through.

Hope this helps (or at least, explains).
