How to send 1000 emails at once Outlook.

Before we get to describe the actual process, we have to discuss the requirements. We will be using Microsoft Excel and Word along with the Mail Merge feature in Microsoft Outlook. The very first thing that you need to do is organize your list of contacts, or your mailing list, using Microsoft Excel.

Create a new Excel spreadsheet and use the first row to place the format for the entire list. The first two columns should be used for the first and last name respectively, the third column for the actual email address. Remember to place each part in different columns, do not place any quote marks, brackets or any especial characters.

List every recipient’s information in a separate row. As an example, the format should be the same as below.

Some useful tips for the Mail Merge feature.

  • You can use the Preview Results button on the Mailing ribbon to see how your email will look like for the intended recipient. Also, you can navigate the preview email for different recipients using the arrows to the right of the Preview Results button.
  • You can split the information in different columns to create a better formatting for your emails and avoid issues with first and last names.
  • Keep in mind that the format of your emails might not support the incorporation of PDF’s or some types of files. The smart thing to do is to create an article online, or add them to a social media platform, then attach a link to the content in the email instead.
