Questions & Answers

Common questions

What if I don't qualify?

Not every business is a fit for our pay-per-call model. If we can't take you on, we'll refer you to our sister brand 100Customers.com, which offers traditional direct mail campaigns at affordable flat rates.

How do you verify calls are real?

Every call is routed through a dedicated tracking number. AI transcription analyzes each call in real-time. Spam, robocalls, and wrong numbers are automatically excluded. You only pay for legitimate prospect conversations.

What determines my cost per call?

We look at your geographic market, industry competition, average customer value, and online reputation. Businesses in less competitive markets with strong reputations typically get the best rates.

Can I set a budget cap?

Absolutely. You set a maximum number of calls per month. Once you hit your cap, we pause the campaign. You're always in control of your spend — no surprises.

Who pays for printing and mailing?

We do. That's the Call.Science promise. We invest our own money in designing, printing, and mailing postcards. Our incentives are perfectly aligned: we only make money when you get real calls.

Is there a long-term commitment?

No. There are no contracts, no minimum terms, and no cancellation fees. If you want to pause or stop, just tell us. We think you'll stay because it works, not because you're locked in.
