Prerequisites for sending emails

To send emails to your customers, you will need to:
  1. Define an organization email in Settings > [Your billing entity] > General > Informations;
  2. Optionally, add your organization’s logo;
  3. Turn on the relevant email scenarios in Settings > [Your billing entity] > Email scenarios;
  4. Define the customer’s email address during customer creation/edition;
  5. To send invoices to multiple recipients, define multiple email addresses at the customer level, separated by commas. (e.g. billing@acme.com,accounting@acme.com,finance@acme.com)

​
Email scenarios

Lago automatically sends email notifications to your customers in three key scenarios:
  1. When an invoice is finalized (including subscription invoices, one-off invoices, or credit purchase invoices);
  2. When a payment receipt is generated for a successful payment; and
  3. When a credit note is issued to adjust or refund an invoice.
By default, all scenarios are switched off. To turn these scenarios on/off:
  1. Go to Settings;
  2. Open the Emails tab;
  3. Toggle each scenario on/off; or
  4. Click on a scenario to see the corresponding email; and
  5. Use the toggle in the upper-right corner to switch this scenario on/off.
To avoid sending too many notifications to customers, we have deactivated emails for invoices without fees.Although invoices with "fees_amount_cents": 0 are not sent to customers by email, they are available in the database and user interface.

​
Email locale

The content of the email will be based on the organization or customer’s document locale. This means that the email will have the same locale as the invoice sent.

​
Email sending address

For the cloud version, Lago uses no-reply@getlago.com as the sending email address. Any responses from your customers will be directed to the email address you have established for your organization in the organization settings.

​
Email template

As mentioned above, some information in the email template can be customized based on the settings of your account, including:
  1. The logo of your organization;
  2. The name of your organization; and
  3. The email address of your organization.

​
Resend emails

If you need to resend an invoice, a credit note or a receipt email, Lago makes it easy to do so with full control over the recipients. To resend an email:
  1. Navigate to the specific invoice or credit note you want to resend;
  2. Click on the Resend email button in Actions menu;
  3. In the dialog that appears, customize your recipients:
    • To: Enter the main recipient email addresses
    • CC: Add any recipients who should receive a copy
    • BCC: Add any recipients who should receive a blind copy
  4. Click Resend to send the email to your selected recipients.
You can send the email to different recipients than the original email. This is useful when you need to forward invoices to different departments or team members.
