Estimate your savings & ROI
Mailing/shipping calculator
# of mailers or packages you process/mo.
% with bad addresses
According to the USPS, 4-5% of mail and 5-10% of packages are returned undeliverable as addressed.
Enter your % as a whole or rational number. For example, for 8%, enter "8". For 8.5%, enter "8.5".

Costs of redelivering
Factor in the costs of postage, shipping & handling, and operations/support to resend the item to the correct address. If shipping through a carrier like FedEx or UPS, include an additional $18-$20 fee by them for address corrections or returns. The impact of reputation damage and lost customers is harder to quantify and not included here, meaning this calculator likely provides a conservative estimate of cost savings and ROI.
Enter your dollar amount as a whole or rational number. For example, for $20, enter "20". For $20.50, enter "20.5".

Can I get international address verification cheaper somewhere else?
Can I get international address verification cheaper somewhere else?
Yes and no.
You can get it cheaper on the front end but more costly on the back end. Also, some providers play “credits” shenanigans, making it difficult for you to understand your actual costs. Smarty's pricing is clear.
It’s a "let's-be-transparent" and “get-what-you-pay-for” kind of thing with significant consequences following implementation.
Be aware that cheaper will mean less accurate and higher operational costs. Smarty gives you global coverage, lightning-fast address lookups, and top-tier accuracy—so you save more in the long run by avoiding failed deliveries, wasted postage, and bad data costs. Smarty is your Goldilocks solution; we’re not the most expensive and we’re not the cheapest, but we are the best value and drive the best ROIs.
To stop worrying about cost, do a free-trial comparison between Smarty and the other guys. We’re begging you. Then calculate the operational savings that better data gives your company. Smarty is the safe and easy ROI decision.
