Follow-up letters for door-to-door teams, written your way
Reps check a box on the pin and KnockKnockGO! turns the day’s knocks into one print-ready PDF of personal letters. Your wording, your logo, your photos, in the envelope you already mail.
How it works
A rep knocks, then checks the Send letter box on the pin. They choose which letter to send and add a photo of the front of the house, plus a photo of any damage they noticed.
Every evening, KnockKnockGO! builds the day’s letters into one print-ready PDF, one page per house, with a recap page up front showing how many letters to mail and the details for each. The PDF is emailed to the list your company sets, and each rep gets a copy of just their own letters.
Owners and admins choose the hour the email goes out, and can switch letters on or off for the whole company.
Customize every letter
Letters are not a fixed form. Company owners and admins edit them in a block editor, so the letter says what your company wants it to say, in your voice.
- Edit the wording of every letter
- Add headings, paragraphs, bullet lists and pictures
- Use your logo, badges and QR code from your own image library
- Fill in the homeowner, rep, date and company automatically
- Print each rep’s name, title and headshot on their letters
- Keep several letters and let reps pick the right one
Starter letters are included for roofing teams (noticed damage, three-tab shingles and older roof). Other trades can rewrite the starters or start from a blank letter.
Built for the envelope
Pick the envelope your company mails in: standard window, large window, double window, no window or a custom size. A large window can show the front-of-house photo. The return address prints without a name or logo by default, and your logo can be added if you want it.
You control what goes out
Owners and admins manage the letters, the image library and the settings. Reps send letters from the pin sheet, and the pictures and headshots on each letter are the company-approved ones, so reps cannot upload their own images into a letter.
Included in every plan
