# Email Campaigns - Basics

Mail merge is painful and takes a long time. Sending emails using Nomsa is not. Learn how to quickly send mass emails using Nomsa.

## The basics

## No prerequisite

Nomsa will handle the email sending for you. **You do not need to do anything to start using our service**. Simply log in and start using Nomsa. Go back to [Quick Start](/campaign-guide-general/how-to-send-a-campaign.md) to learn how to use Nomsa.

## Customising your Sender Details

You can customise the sender field when creating your campaign in step 1. The email will be received by recipients as “*`Your agency name`*` `` ``via ` Nomsa ”, with the default sender email address for all Nomsa campaigns being `donotreply@mail.nomsa.gov.kh.`

You can also choose to send a copy of each email that each recipient in your contact list receives, by clicking on the "`BCC to me`" checkbox. This will send a copy of each email to your inbox.
