InboxDollars

InboxDollars is a veteran of the GPT space, founded in 2000 and now owned by Prodege (parent of Swagbucks and MyPoints). Its biggest differentiator is its currency model: instead of points that convert to dollars, InboxDollars tracks everything directly in USD. For users frustrated by the "1,000 points = $1" math of most competitors, this alone makes the platform worth a look.

The earning menu covers the standard GPT territory — surveys, offers, videos, cashback shopping, email click-throughs, and daily polls. Survey payouts typically range from $0.25 to $5.00 each, with most clustering around $0.50 to $1.00. The Offer Wall tends to deliver the highest-value tasks: app downloads, free trials, and in-game challenges.

In 2025, InboxDollars added Tapjoy as an offer wall partner, significantly expanding the catalog of game and app offers. This was a meaningful upgrade for users focused on offer completion.

The main drawbacks are the $30 minimum cashout threshold and US-only availability. The $30 threshold can take weeks to reach for casual users, which has generated plenty of complaints. Like all GPT sites, survey disqualification is also a recurring frustration.

For US users who prefer transparency and a brand with a long payment track record, InboxDollars is a solid secondary platform. Pair it with a higher-ceiling site like Freecash for best results — or run it alongside Swagbucks and MyPoints to maximize Prodege's multi-platform footprint.
