Are your customers not receiving your invoices, sales receipts, estimates, statements or reports via email? Here are three possible reasons why, and how you can fix the problem.

Solution 1: Reset your email address

If you recently imported QuickBooks Desktop data into a QuickBooks Online company, you may need to reset your email address:

  1. Select the Gear icon on the Toolbar.

  2. Under Your Company, select Account and Settings (or Company Settings).

  3. In the Contact info section, review each email address, then make changes as needed.
  4. Select Save and then Done.

Solution 2: Clear and re-enter your email address

If solution 1 doesn't apply, ask your customers to check their junk mail and spam folders. If the email is still not found, clear and then re-enter your email address.

  1. Select the Gear icon on the Toolbar.

  2. Under Your Company, select Account and Settings (or Company Settings).

  3. In the Contact info section, select Email.
  4. Clear the Company email field and enter the desired address, even if it appears correct as is. (Note: Be sure not to use any extra characters or spaces before, within, or after the address you enter.)
  5. Select Save and then Done.

  6. Send yourself a test transaction.
  7. If you still don't receive the email, try using a different email address that has a different domain (for instance, if you were using a Gmail email address, try a Hotmail or Yahoo address instead.)

Solution 3: Configure server to accept QuickBooks Online mail server host names and IP addresses

If those solutions don't work, you may need to ask an IT expert to have the QuickBooks Online mail server host names and IP addresses be added to your outgoing mail servers.

Many email programs use various blocking mechanisms on their mail servers. Also, many email servers don't accept mail from server IP addresses without reverse DNS entries that match the domain name that the server alleges to be representing. This is an anti-spam measure to prevent spammers from pretending to deliver mail from well-known domains.

When you send a sales form/statement to your customer, the emailed invoice looks as though it's coming from your mail server when, in fact, it's being sent from a QuickBooks Online mail server. Your mail servers might have this type of "spoofing" blocked.

To allow mail to pass through your mail servers, configure your server to accept QuickBooks Online mail server host names and IP addresses. The steps to add the host names and IP addresses depend on your e-mail setup. Below is a list of Host Names and IP addresses you need to add.

If you need to specify a subnet mask, you can use 255.255.255.255

Now your customers can receive your emails from QuickBooks.
