Set up email sending and connect your mailbox
Emails don't send until you turn on email sending and connect a mailbox, so do both before your first automated or manual send: enable sending in Email Settings, then connect and select your mailbox under Email Account.
Turn on email sending
Email sending is off by default, and nothing (automated or manual) goes out until it's enabled. The setting lives in Email Settings in Settings.
Open Email Settings in Settings.
Turn on Enable Email Sending. The page shows whether email sending is currently ENABLED or DISABLED.
Click Save.
A "Settings saved successfully" confirmation appears. Once sending is enabled, a Send Rejection Emails control also appears on the page.
Connect your mailbox
Connect a personal mailbox so Happlicant sends email from your own address. You can use Google, Microsoft, or an SMTP/IMAP connection, all under Email Account in Settings.
Open Email Account in Settings.
Configure a connection using Google, Microsoft, or SMTP/IMAP.
Select the provider you just connected and save it.
An unselected connection doesn't send email. Configuring a provider isn't enough; you must select it and save for your mailbox to be used.
Edit the default email templates
Email Settings also holds your default Email Templates:
Application Email, with the default subject "Application Submitted".
Rejection Email, with the default subject "Update on your application".
Interview Email, with the default subject "Invitation to Interview".
Each template has an Edit Template control. The editor has Email Subject and Email Body fields; make your changes and click Save Changes.
Editing these global templates affects future jobs only, not your current jobs. To apply a template to jobs that already exist, use Apply to All Existing and New Jobs, which cannot be undone.
