Kleinanzeigen Message Filler

Auto-fill rental inquiry messages on kleinanzeigen.de with poster name and available-from month.

Kleinanzeigen Message Filler — Auto-fill rental inquiry messages in one click Searching for an apartment on kleinanzeigen.de means sending dozens of near-identical inquiry messages — each one needing the landlord's name and the right move-in month. Doing that by hand is slow, error-prone, and exhausting. Kleinanzeigen Message Filler solves this in a single click. When you open a rental listing and click the "Fill Message" button that appears next to the contact form, the extension automatically: - Reads the poster's name from the listing page - Detects the available-from date ("Verfügbar ab") — handling German month names, full dates, and short formats like 03/2026 - Injects a complete, professional inquiry letter into the message box, personalized with the real name and the correct month You go from a blank form to a ready-to-send message in under two seconds. A professional template, ready to use The default template is a well-structured German rental inquiry that introduces you, lists your occupation, income, lifestyle, and household size, and confirms you have all required documents (Einkommensnachweis, Mieterselbstauskunft, Schufa). It is the kind of message landlords actually want to read. You fill in your personal details once — your name, job, income — and every listing gets a tailored message automatically. Fully customizable Click the extension icon to open the editor. You write your own template using two smart placeholders: - {name} — replaced with the poster's name extracted from the listing - {month} — replaced with the available-from month detected from the listing A live preview tab shows you exactly what the filled message will look like, with sample values highlighted in color so you can spot any missing or mis-formatted text before you save. You can reset to the default template at any time with one click. Why this extension exists Germany's rental market moves fast. Landlords receive many inquiries and often choose based on the quality and speed of the first message. Sending a generic "Ich interessiere mich für Ihre Wohnung" puts you at the back of the queue. Sending a personal, well-formatted letter — that addresses the landlord by name and correctly references when you want to move in — makes you stand out. This extension lets you send that quality of message to every single listing, without spending three minutes typing it out each time. How it works — step by step 1. Open any apartment listing on kleinanzeigen.de 2. Scroll to the contact / message form 3. Click the Fill Message button that appears above the text box 4. The message is filled instantly — personalized with the poster's name and available-from month 5. Review, add your personal details in the bracketed fields, and send If the available-from date cannot be found on the page, the extension fills the message anyway and highlights the placeholder so you know exactly what to fill in manually. Privacy first This extension does not collect, transmit, or store any personal data. Your message template is saved locally in your browser's sync storage (Chrome Sync) so it follows you across devices — but it never leaves your Google account. The extension only runs on kleinanzeigen.de pages. No analytics, no tracking, no external servers. Permissions explained - Storage — to save your custom message template across browser sessions - kleinanzeigen.de — to read the poster name and available date from listing pages, and to inject the Fill Message button into the contact form No other permissions are requested. Who is this for? - Anyone actively apartment-hunting in Germany on kleinanzeigen.de - People sending inquiries to multiple listings per day who want each message to feel personal and professional - Expats or international residents who want a correct, native-sounding German inquiry template they can rely on - Anyone who has ever accidentally sent "Sehr geehrte/r [Name]," without filling in the name Tip: Personalize the template once with your actual name, job title, income, and household size. After that, every listing gets a real, tailored message with zero extra effort. Works on kleinanzeigen.de — Germany's largest classifieds platform (formerly eBay Kleinanzeigen).
