Upload a List: Mail in a Few Steps
Your list, your creative, we print and mail.
If you have a spreadsheet of addresses, you have everything you need. Upload it, pick your mail piece, approve the preview, and SendMailr takes it from there: professional printing, postal delivery, and tracking included. Big enough send? You may see volume-based savings on the mail in your order summary.
Who This Is For
Any business or professional with a customer, client, or prospect list who wants to send a one-time or occasional campaign.
Teams that already have lists ready to go (from a CRM export, an event sign-up sheet, or a purchased database) and just need a fast, clean way to mail.
Anyone who has relied on mail houses in the past and wants a modern, self-serve alternative with transparent pricing.

Frequently Asked Questions
What file formats can I upload?
SendMailr accepts CSV and Excel (.xlsx) files. The file needs to include at least name and a U.S. mailing address for each recipient.
Is there a minimum number of recipients?
SendMailr may enforce a small minimum for each Upload & Mail send; you will see the requirement in the app when you build your order.
Do you offer discounts for mailing to a lot of people?
Yes. Upload & Mail can include volume-based discounts when your send size meets the thresholds in your account. The exact step pricing and any mail-only discount appear in your order summary before you pay; flat per-order fees are separate.
What happens if my list has bad addresses?
SendMailr flags addresses that fail validation. You can review and remove them before approving the send.
Do you deliver outside the U.S.?
No. SendMailr delivers to U.S. addresses only.
How long does delivery take?
Typical delivery is 3–7 business days after production completes. Tracking shows real-time status per recipient.
Can I upload the same list for a repeat send next month?
Yes. You can save your list and design and reuse them for future sends. You're not locked into any single campaign structure.
