Comparison
RevAddress vs Smarty
Same USPS data. Demographics, rooftop geocoding, and deliverability scoring bundled at $79/mo — not premium add-ons, not annual commitments.
Smarty meters per lookup and charges separately for Property (demographics) and geocoding — mid-market annual contracts run $5K–$25K/yr. RevAddress Growth is $79/mo flat, month-to-month, everything included.
What you pay at scale
Smarty sells lookups à la carte — base validation, plus Property data add-on (~$3K+/yr), plus geocoding add-on. RevAddress Growth bundles all three at $79/mo flat.
| Monthly volume | Smarty | RevAddress | Difference |
|---|---|---|---|
| 1,000 lookups / mo (+ demographics + geocoding) | ~$350/mo | $79/mo Growth | ~$271/mo |
| 5,000 lookups / mo (+ demographics + geocoding) | ~$400/mo | $79/mo Growth | ~$321/mo |
| 10,000 lookups / mo (+ demographics + geocoding) | ~$450/mo | $79/mo Growth | ~$371/mo |
| 50,000 lookups / mo (+ demographics + geocoding) | ~$1,250/mo | $199/mo Pro | ~$1,051/mo |
Smarty all-in cost estimated from public pricing page + documented Property add-on (~$3K+/yr per the April 2026 audit) and geocoding add-on. RevAddress: flat $29/$79/$199 tiers, no add-ons. Sources: docs/competitive/compare-audit-2026-04.md.

Why developers switch from Smarty
Demographics and geocoding are premium add-ons
Smarty's Property API (demographics) runs roughly $3K+/yr on top of base validation, and geocoding is a separate subscription. RevAddress /api/address/demographics and /api/address/geocode are bundled in Growth at $79/mo flat — Census ACS tract-level data and rooftop coordinates included.
No fraud or deliverability scoring
Smarty validates and enriches but does not score. RevAddress /api/address/intelligence returns 6 fraud signals (velocity, vacancy, PO Box, commercial mismatch, high-risk ZIP, forwarding) plus an A+→F deliverability grade with every Growth-tier call, cache-first from D1.
Annual contracts lock you in
Smarty's best pricing requires 12-month commitments at $5K–$25K/yr. RevAddress is month-to-month. Cancel anytime. Move between Starter/Growth/Pro without contract renegotiation or discount clawback.
