There are four options available to choose from: ### **Letter** With the type "Letter", you can create a message as an email with a PDF attachment or generate a PDF that can be printed and mailed. ### **Invoice** With the type "Invoice," standardized invoices can be generated for both members and non-members. Various invoice items and the bank account can be specified. ### **Welcome letter** This allows, for instance, new club members to be welcomed by the club or district with a welcome letter. The process of creating a welcome letter is the same as that of producing a newsletter. It is advisable to create a template and replicate it accordingly. ### **Letter to the bereaved** The template "Letter to the bereaved" serves as a template for a condolence message directed to the widow or widower of the deceased member. It can certainly be modified before sending.
