This is a feature designed especially for users/companies that receive many emails, so what they require is a way to send each notification to multiple email addresses whenever someone submits the web form. They will have their business processes fastened if the emails are sent directly to the department that should handle the issue.
For example, company ABC – who has got 3 departments: cars, motorbikes, trucks – receives all filled contact forms to the same email address: firstname.lastname@example.org. The ABC employee that handles filled contact forms sorts the emails and forwards car related emails to email@example.com, motorbike related emails to firstname.lastname@example.org and truck related emails to email@example.com. This is time-consuming and adds some delay to the reply action. By using custom recipients, company ABC will have the filled contact forms sent directly to the right addresses.
To add custom recipients as well as conditioning them to multiple email addresses, go to Settings → Notifications and click on Add Rules.
You’ll see that the email address used for creating your account is, by default, set to receive all submissions. Press Duplicate to create a new rule.
Type a new address in the text box and choose, in the second dropdown list, the field that will affect the submission’s behavior. Then specify the particularities that it needs to meet.
E.g.: Address – contains – Boston. This means that the submissions in which the Address field contains the word Boston are considered.
In the first dropdown list, you can select Send to or Only Send to. If you select Send to, then the submissions that meet the conditions will be sent to both the primary email address and the one added afterward. If you select Only Send to, then submissions will only be sent to the newly added address.
Save the changes and your email rules will be added.
