Magento – Sales emails not being received

There are two separate sections that handle the Magento emails:

1. Store Email Addresses define addresses for senders of mails sent by the system. (General, Sales, Support)

2. Sales Emails define which emails are sent and by which sender (as well as sending a copy to an admin if you would like to receive one).

3. System->Configuration->General->Store Email Addresses are only the sender addresses that will appear in the emails sent. These fields have nothing to do with admins receiving emails or order notifications. It's just a place to define sender email/return address for the system to use in the header. General Sales, Sales Representative, Support, etc.

4. System->Configuration->Sales->Sales Emails is where you configure which of the Store Email addresses you specified in the Store Email Addresses section will be the sender of New Orders, Comments, Invoices, etc. By default, customers receive new order emails from the Sales Representative email address defined under Store Email Addresses

Sales Emails is where you configure the system to send a copy of an order to you as the admin, under (Send Order Email Copy To:)

Change your settings to allow less secure apps to access your account. We don't recommend this option because it might make it easier for someone to break into your account. If you want to allow access anyway, follow these

steps:

• Go to the "Less secure apps" section in My Account.

• Next to "Access for less secure apps," select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)
