KNOW WHICH POPLAR MAILINGS ACTUALLY CONVERT.
Connect Poplar to Menza and ask which direct mail campaigns, creatives and audiences are actually pulling their weight — what each mailing costs, which creative wins, who should never be mailed again. Menza reads it live through the official Poplar API, and when it proposes a change, such as updating a suppression list, it waits for your approval.

What can Menza do with Poplar?
Stop paying to mail the wrong people
Menza spots recipients who've already converted or gone stale, proposes adding them to your suppression list, and — once you approve — updates it before the next drop goes out.
Find your winning creative, with numbers
Ask which creative performs and Menza compares mailings side by side across campaigns, so the next print run backs the design that converts rather than the one someone prefers.
Know what every campaign really costs
Menza reads mailings and campaign data live, so cost per delivered piece and per conversion are one question away — no more reconciling invoices against spreadsheets.

Poplar questions, answered.
How does Menza connect to Poplar?
Through your Poplar API key. You paste it once and Menza stores it encrypted; it is never shown to the AI. From then on Menza queries the official Poplar API directly — campaigns, mailings and audiences, live, with nothing to export.
What can Menza answer about my Poplar data?
Anything in the API: direct mail campaigns, creatives, individual mailings, audiences and suppression lists. Ask which campaign drove the most conversions, how a creative performed by audience, or how many pieces mailed last week — and get the current answer.
Is my Poplar data safe with Menza?
Yes. Your API key is encrypted at rest and never exposed to the AI, and Menza only touches what the key allows. When it proposes an action — like updating a suppression list — nothing changes in Poplar until you explicitly approve.
Can Menza tell me a mailing's cost per conversion?
Yes. Menza reads mailings and campaign performance straight from Poplar, so you can ask for cost per conversion by campaign, creative or audience and compare drops over time — the arithmetic you used to do in a spreadsheet, done for you.
