To send reminders or demands for payment by email, you must first check and, if necessary, update the settings for reminders.
Check reminder settings
To check and/or change the settings for your reminders or demands for payment:
- click on the Settings icon in the navigation bar
- in the now-opened screen, click on Reminder settings
- then open the Manual reminders tab to change the sending method if necessary
- then open the Layouts tab to change the default layout of one of the four standard reminders: payment notification, reminder, demand for payment and formal notice, if necessary.
Before you actually send the reminders or demands for payment in bulk:
- you can, if required, change the reminder level
- you can, if required, change the sending method
- you can, if required, change and select the correct reminder layout.
ATTENTION!
Make sure the login credentials (username or password) for the SMTP server (which handles email) are correct. If the credentials are incorrect, the following message will appear: “Check your username and/or password. 535 5.7.8 Error: authentication failed: authentication failure.”
Yuki does not support two-step authentication for email sending. Clear the mail server settings so that the Yuki server can handle the email.
