Two people, one address, one piece of mail.
Made for realtors' client lists, and for anyone who mails to people at home.
1perDoor turns your list into one mailing line per household, so you don't pay to mail the same door twice.
Coming soon to the App Store for iPhone
How it works
- Open your list. A CSV or Excel file from your CRM, Google Sheets, Excel or Numbers.
- Pick a style. See before and after for each way of writing names, such as "John and Mary Smith".
- Check the grade. 1perDoor groups people at the same address and shows how clean your list is.
- Correct what's marked. Households it can't write with confidence are marked for review. It doesn't guess.
- Export. One line per household, ready for your mailing house.
Who it's for
Made first for realtors, and for anyone whose list has a row per person when the mail goes to a door.
- Realtors: closing anniversaries, holiday cards and just-sold postcards to past clients.
- Dental and medical offices: recall reminders, so a family of four gets one card, not four.
- Nonprofits and churches: appeal letters and newsletters to donor and member households.
- Small businesses: customer postcards and catalogs.
- Schools, clubs and HOAs: family mailings from a roster that lists each person separately.
- Weddings and parties: invitations from a guest spreadsheet.
Private by design
- Your file is read and processed on your iPhone.
- Your work in progress is saved on your iPhone and, if iCloud is on, in your own private iCloud.
- No accounts, no tracking, no ads, no analytics. Nothing you open is ever sent to us.
Made for a realtor
I built 1perDoor because my daughter, a realtor, needed it several times over six months. Every closing-gift and holiday mailing started with the same cleanup of her client list. I thought it might help you too.
Pricing
Try the whole thing free with built-in sample data. With your own list, you can see the preview, the styles and the grade for free. Correcting and exporting your own lists costs $25 every 3 months, $80 a year, or $100 once for life.
What you need
An iPhone with iOS 27.1 or later. 1perDoor makes the most of iPhone Duo's inner display. Available in the United States.
1perDoor makes each address one mailing. Your mailing house still does the USPS work, such as address standardization and ZIP+4.
