Changing the “SMTP Settings”

By default, “Online Invoices” sends emails on the user’s behalf using “Online Invoices” email address “” to deliver the emails successfully to their clients without bouncing back or being rejected by the email server.

Although the email is being sent by “”  however when the client clicks the “reply” button he will be sending the reply back directly to the business owner’s email address directly.

What if you would like to send your emails from your own email server directly and remove the “”.

To be able to do so you will have to edit the “SMTP Settings” on “Online invoices” software and grant “Online Invoices” the access to send those emails by following these steps below:


  1. Through the “Settings” tab, select the “SMTP Settings” option.
  2. Tick the “Send emails using my SMTP account” checkbox on the left-hand side to enable the “SMTP Settings”.
  3. Enable “SMTP settings” from your email provider (Google, Hotmail, Yahoo or your own server) and get the following details:
    1. “Email Address”: Your email address which you use for the “Online Invoices” system.
      • “Note”: you can use another email rather than the one you are using on the system but when the customer presses  “reply” he will  be replying to the system’s email, not the sender’s email just like as it is sent from “”
    2. “Email Sender Name”: Your name or your business name.
    3. “SMTP User Name”: Typically the same email as your “Email Sender Name” check with your email provider if there are different settings to add.
    4. “SMTP Password”: Your email password. – this is optional as some servers don’t require authentications.
    5. “SMTP Server”: Check with your email provider for this settings. E.g. Google uses this host “”.
      1. If you are using Gmail you need to do the following steps first:
        1- Click this link below.
        And Select the “Turn On” option.
        2- check this link below.
        And then click “Continue”
        Important Notes:
        it is recommended to use a non-free STMP, as many free SMTP accounts such as Gmail prevents you from sending invoices in emails messages for security purposes, and you will be able to know that if the email message has been bounced back to your email inbox.
    6. “SMTP Port”: Check with your email provider for the “SMTP Port” they are using. E.g. 25, 26. Also, you can leave it empty to use the “default port: 25”
    7. Tick the checkbox if your server requires “SSL” connection.
  4. Click the “Submit” button to save the changes.
