Mail to Everyone on Your List Without Leaving Your Desk
Mailform's bulk mail tool lets you upload a document and an address list, then handles everything else: printing, folding, stuffing, stamping, and mailing via USPS. Whether you're sending 10 invoices or 10,000 rent notices, the process is the same — upload, review, send.
Pricing starts at $2.99 per letter for the first page, plus $0.49 per additional page. Volume discounts bring the per-letter cost down to as low as $1.01 for large batches. No monthly fees. No minimums. No contracts.
How Bulk Mailing Works
- Upload your document — Upload a single PDF to send to all recipients, or upload individual PDFs matched to each recipient. Mailform supports letters, invoices, legal notices, statements, forms, and flyers.
- Add your recipient list — Upload a CSV or Excel file with names and addresses. Mailform maps the fields automatically. You can also pull from your Mailform address book or import contacts from QuickBooks, FreshBooks, or other integrations.
- Set your mail options — Choose USPS First Class Mail or Certified Mail per recipient. Select color or black-and-white printing. Add a return envelope for $0.50 per letter if recipients need to mail something back.
- Review and send — Confirm your recipient list and options, then submit. Mailform prints, stuffs, and drops every piece at USPS on your behalf.
What You Can Send in Bulk
- Invoices — Mail monthly invoices to all your clients at once. Import directly from QuickBooks, FreshBooks, Xero, or upload a PDF batch.
- Rent reminders and notices — Property managers can send payment reminders, lease renewals, or notice-to-quit letters to all tenants in one batch.
- Legal notices — Law firms can mail required notices to multiple parties, with Certified Mail tracking for proof of delivery.
- Annual statements — Send year-end account summaries, tax documents, or benefit statements to all clients or members.
- Insurance renewals — Mail renewal notices and policy updates to policyholders via USPS.
- HOA notices — Homeowners associations can send meeting notices, assessment letters, and violation notices to all members.
- W-2 and 1099 forms — Mail tax documents to employees or contractors at year-end without printing anything yourself.

How Mailform Compares to Other Bulk Mail Services
Lob is an API-first platform built for developer teams at enterprise scale — it requires engineering resources to set up and is designed for high-volume programmatic mail. PostGrid and Stannp are similar: built for marketing campaigns and enterprise direct mail programs. Click2Mail is a USPS partner focused on marketing mailers and postcards.
Mailform is different. It's built for businesses and professionals who need to mail documents — not marketing campaigns. Key differences:
- No minimum order — mail 1 letter or 10,000, pricing is the same per-letter rate
- No monthly fee — pay only when you mail something
- No developer needed — upload a PDF and a CSV from your browser
- Accounting software integrations — import invoices directly from QuickBooks, FreshBooks, Xero, and more
- Document-first — designed for invoices, legal notices, and statements, not postcards or marketing flyers
