Does Hubi work in PostGrid test mode before I go live?

PostGrid separates test and live API keys, and test keys generate mailpieces without printing or charging. Hubi acts with whichever key you connect, so connect the test key while you trial it.

Can Hubi print checks, or only letters and postcards?

PostGrid supports letters, postcards, and printed checks, and Hubi can create each where your account has that product enabled. Check sending may require extra account verification.

What does address verification actually return?

Hubi reports PostGrid's verification result - whether the address is deliverable and its standardized form - so you can fix bad addresses before paying to mail them.

What does Hubi need to connect to PostGrid?

Hubi authenticates with the PostGrid API key you generate in your account and acts within that account's products, templates, and balance.

Can Hubi tie PostGrid to my store and other tools?

Yes. You can chain PostGrid with anything connected - for example mail a PostGrid postcard to every Shopify customer in a segment - in one instruction.

All Integrations

Physical mail still cuts through where email gets ignored, but printing, stuffing, and posting a letter is the reason most stores never send it. Hubi sends letters, postcards, and checks through PostGrid and verifies addresses from a plain instruction, drafting each mailpiece for your approval before it goes to print.
