Upload & Send

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.

Who This Is For

1

Any business or professional with a customer, client, or prospect list who wants to send a one-time or occasional campaign.

2

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.

3

Anyone who has relied on mail houses in the past and wants a modern, self-serve alternative with transparent pricing.
