Mail your own list

Your past lists: who you wrote to and why anyone was removed →

Already have a list of homes you want to write to? Upload it and we will check the roofs, add a personalised solar image to each letter, and post them for you.

1. Upload your list

Any CSV file with addresses in it. It does not need to be tidy: we work out which column is which, and you can correct us. In Excel or Google Sheets choose Save as or Download as CSV. Up to 50,000 rows, 5 MB.

Your file is scanned for viruses, is only used for this campaign, and is not shared with anyone. Names are used only on the envelope and the greeting. We do not keep your list. 30 days after you approve your mailing we delete it, and the roof, location and letter data with it. All we keep is a record of what happened to each home, so you can see who you wrote to.
