Let agents send your physical mail for you
QX drafts, addresses and ships letters, postcards and checks through Postgrid—so your team runs direct mail at scale without ever touching an envelope.
Stop wrestling with mail merges, address errors, and check runs. Hand your physical mail to an agent.
Campaigns that mail themselves
Turn a list of contacts into hundreds of personalized letters or postcards—each one merged from a template, verified, and shipped through Postgrid without manual touch.
Checks cut on autopilot
Refunds, vendor payouts and rebates get drafted, approved and printed as physical checks—pulled from the right bank account and mailed to a verified address.
Never mail to a bad address
Every recipient is verified and standardized before a single envelope ships—bounces, returns and wasted postage get caught before they cost you anything.
