Every email that leaves your office is a small business letter. For companies and registered businesses, the law sets out what it must contain, and clients expect a phone number, an address and a way to your website. The generator combines both into a clean signature that looks the same in all common email programs.
Which details belong in an email signature
In Austria, § 14 of the Commercial Code (UGB) requires every business entered in the Firmenbuch (company register) to state on its business letters, in whatever form, and therefore also by email: the company name with its legal form, the registered office, the Firmenbuch number and the Firmenbuch court. That applies to a law firm GmbH just as much as to a tax advisory GmbH or a bookkeeping office run as an e.U. Leaving the details out risks coercive penalties imposed by the Firmenbuch court.
In Germany, several laws cover this: § 37a HGB for registered merchants, the HGB for OHG and KG, the PartGG for partnership companies and § 35a GmbHG for GmbH and UG. A GmbH also names all managing directors with their surname and at least one first name written out in full. Self-employed lawyers, tax advisers or mediators without a register entry have no statutory mandatory details in their emails, but a complete signature is still standard.
Why the signature is built as a table
Email programs display HTML very differently. Outlook on Windows uses Word’s rendering engine, Gmail strips stylesheets, and Apple Mail likes to apply its own default font. The generator therefore builds the signature the way newsletter professionals do: as a table with fixed spacing, Arial as the font and all colours set directly on the elements. That way, it looks the same for recipients as it does in the preview.
The signature deliberately does without images and logos. Many programs block images until they are allowed, show them as attachments or turn a short reply into an email with several files. An accent colour from your letterhead and a clear font look more professional than a logo that arrives as a paperclip.
What else makes a good signature
Keep it short: name, role, office, phone, email, website and address, with the mandatory details in small print below. Quotes, advertising banners and long lists of social media links are distracting. A link to online appointment booking, on the other hand, saves you and your clients the back and forth by email. For replies and forwards, a shorter version such as the compact layout is enough in many programs.
