# Custom email address

## Overview

When you send an email through FastField, such as a notification or submission report, it will be sent from this default address: [noreply@fastfieldforms.com](mailto:noreply@fastfieldforms.com,). However, it is possible to customize this ***From*** email address, as well as a ***Reply-To*** address to allow any responses to be sent to an email address of your choice.

The following instructions explain how to set this up on your account. If you have any questions or concerns, please feel free to [reach out to our team](/fastfield/docs/need-additional-help)**.**

## How to set up the *Reply-To* email address

1. In the Portal, go to **Account** > **Company Settings**.
2. Go to the **Email Settings** tab and scroll down to **All Email Setup**. ![All Email Setup section in the Email Settings tab](https://cdn.document360.io/dd260e4e-10bb-4b66-8fb3-5504c272b904/Images/Documentation/17592273991309?sv=2026-02-06&spr=https&st=2026-10-31T10%3A04%3A35Z&se=2026-10-31T11%3A04%3A35Z&sr=c&sp=r&sig=trjUqnGys7qu%2BTJZQparnwxda4UCLCbB%2B1JUVuTuBo4%3D)
3. In the **Support Reply-To Email** field, enter the email address you want recipients to send any replies to.

## How to set up the *From* email address

It is possible to set up FastField as an authorized sender, allowing you to change the ***From*** email address. This will require you to have a custom domain, as you will need to modify the **CNAME** records on your **DNS** server. Generic emails, such as [gmail.com](http://gmail.com/) or [yahoo.com](http://yahoo.com/), will not be able to complete this optional setting.

1. In the Portal, go to **Account** > **Company Settings**.
2. Go to the **Email Settings** tab and scroll down to **All Email Setup**.
3. Just below the **Reply-To Email** field, select **Begin Setup** to begin the custom *From* email address setup. ![Begin Setup button for the custom From email address in Company Settings](https://cdn.document360.io/dd260e4e-10bb-4b66-8fb3-5504c272b904/Images/Documentation/17592233983373?sv=2026-02-06&spr=https&st=2026-10-31T10%3A04%3A35Z&se=2026-10-31T11%3A04%3A35Z&sr=c&sp=r&sig=trjUqnGys7qu%2BTJZQparnwxda4UCLCbB%2B1JUVuTuBo4%3D)
4. In the **Domain** field, **enter the domain** you'd like to use to set us up as an authorized sender, for example, [fastfieldforms.com](http://fastfieldforms.com/).
5. In the **From Email Address** field, enter the email address you want to use for the custom *From* email address (e.g., [noreply@fastfieldforms.com](mailto:noreply@fastfieldforms.com)).
6. Select **Create Custom Email Domain**.
7. You will now need to add the **CNAME** records to your email server.
8. Once you update your server with the required CNAME records, select the blue button to **validate** your domain, completing the process to make FastField an authorized sender to send an email on your behalf.

## Advanced settings: Custom DKIM Selector

This is an optional setting. There may be a scenario for some accounts where you may already have **CNAME** records registered with **Sendgrid**, our email sender. If this is the case, when trying to register with us, it would create a set of duplicate records (and your DNS won't like that). To set this up, select **Show Advanced Settings**:![Show Advanced Settings button in the email domain setup](https://cdn.document360.io/dd260e4e-10bb-4b66-8fb3-5504c272b904/Images/Documentation/4424194142861?sv=2026-02-06&spr=https&st=2026-10-31T10%3A04%3A35Z&se=2026-10-31T11%3A04%3A35Z&sr=c&sp=r&sig=trjUqnGys7qu%2BTJZQparnwxda4UCLCbB%2B1JUVuTuBo4%3D)

1. Under Custom DKIM Selector, enter up to **3 letters** or **numbers.**
2. After you put in your DKIM selector and fill out your domain and *From* email address, select **Create Custom Email Domain** and it will create your CNAME records with your desired DKIM selector.
