This guide applies to the **pro** versions of Heatpunk.
With Heatpunk Pro you can send emails to your customer within the software, by setting up your email credentials it means these emails will send from your domain, rather than from no-reply@heatpunk.co.uk. --- ## **Email configuration** To edit your email settings navigate to **Pro account settings** > **Email.** [](https://help.heatpunk.co.uk/uploads/images/gallery/2025-11/YJpOgUqH6mwB1BuB-image.png) Here you can enter email credentials to allow emails to be sent from your own email address, how this is set up will depend on what email provider you are using. ### **OAuth 2.0 - Gmail or Microsoft 365** If Gmail or Microsoft 365 is your email provider, then simply select **OAuth 2.0**, select the relevant option and click connect, this will direct you to your email where you can approve the connection. Once it is linked, you can send a test email to make sure it's working as intended. ### **SMTP** If you have a different email provider then you will need to set up using the **SMTP** option. What is then required for each field is dependent on provider and you will likely be able to find instructions online by searching for your provider and 'SMTP credentials'. Below is some general guidance for each field| SMTP Username | These credentials are provided by your email service provider and are used to authenticate your email client |
| SMTP From Address | **Optional**: This is the email address that recipients see as the sender of the email. In most cases this will be the same as the SMTP username. |
| SMTP Name | **Optional**: this will appear next to the 'from address'. |
| SMTP Host | This will vary depending on provider. The format will be something like smtp.provider.com. |
| SMTP Password | This will usually be an **App Password** that you need to set up but in some cases it will be your email password. |
| SMTP Port | **Optional**: by default this will be 587 but in some cases this will need to be changed. |
