FAQ
Questions, answered.
Formats, USPS rules, delivery times and billing. If it’s not here, ask us.
Getting started
What is Dardeus?
Direct mail software that works like a good email tool. You design a postcard or letter, pick who gets it, and press send. We print, stamp and mail every piece, then show you what was delivered and who responded.
How long does it take to launch a campaign?
About as long as an email. Pick the type and size, design it, add your audience and pay, usually in one sitting. Printing starts within one to two business days.
Do I need a designer?
No. Start from a template that fits your size, upload a finished PDF, or have the AI skill draft one in your brand. USPS zones are checked as you go.
What sizes can I send?
Postcards in 6×4, 6×9 and 6×11, letters on 8.5×11 in a window envelope, and 12×9 or 17.75×9 self-mailers. EDDM pieces come in 6.25×9 and 6×11.
Can I run mail for several brands or clients?
Yes. Each brand or client gets its own brand kit, with logo, colors, fonts and return address, plus its own lists and results. Your team runs them all from one workspace.
Mail and USPS
What’s the difference between direct mail and EDDM?
Direct mail goes to specific people, addressed by name, from your contacts, a CSV or an integration. EDDM goes to every address on the USPS carrier routes you pick, addressed to “Postal Customer”, with no contact list needed.
How fast does mail arrive?
Pieces print within one to two business days. After that, First-Class usually arrives in 1 to 5 days and Standard in 3 to 10. You can follow every piece from the printer to the mailbox.
Can I pick the date it goes out?
Yes. Send as soon as possible or pick a date, and we print in time to mail it then. Automations send on their own when something happens, like a first order or 60 days since the last one.
Is there a minimum order?
Campaigns start at 500 pieces, and the price per piece drops as you send more. EDDM also needs 200 to 5,000 pieces per ZIP Code a day, a USPS rule.
Will my design pass USPS rules?
Templates come sized with bleed, and the address block, barcode zone and margins are checked as you design. Uploaded PDFs are checked against the size you picked before anything prints.
What happens to bad addresses?
We check every address before you pay. Ones USPS can’t deliver are flagged and skipped, so you never pay to print or mail them.
Pricing and billing
How does pricing work?
You pay per piece, and the price covers printing and postage. Your tier is set by your audience size, and you see the exact total before you pay.
How can I pay?
By card, ACH transfer or prepaid credits. You choose at checkout, after you’ve seen the exact total.
Integrations
Which tools does Dardeus connect to?
Shopify, HubSpot and Salesforce, plus CSV uploads for everything else. Contacts sync live, and automations can start from events in your store or CRM.
How do I know if it worked?
Every piece is tracked from the printer to the mailbox. QR code scans roll up into the campaign and show on each contact, and orders from your store show up next to the campaign that drove them.
No questions match “”.
Try a shorter word, like “postage” or “Shopify”. Or ask us: a real person answers, usually the same day.
