GMass vs Woodpecker
Both of these let you start without paying, which puts them in a small group. The difference is what free means. Woodpecker bills per contacted prospect from $35/mo with unlimited mailboxes; GMass gives you a frictionless trial with no card and no signup form. After that they diverge sharply — one prices on contacted prospects, the other on seats.

Hands-on field test
In progressWe plan to run identical 200-contact campaigns from freshly warmed mailboxes on each platform (same copy, same sending window, same domains) and measure inbox-placement rate via seed tests, plus bounce and reply rates. Until that runs we quote no deliverability figures.
The verdict
Woodpecker is the better long-run choice for anyone who needs more than one mailbox or more than one teammate, because both are unlimited at every usage level and it charges only for prospects you actually contact. GMass is the faster start and the more predictable bill, with a clear $20/mo annual rate — but it is Gmail-only, and its team pricing is per seat, which is the opposite of Woodpecker's model.
Choose GMass if you are one person in Gmail who wants a predictable flat price and no setup at all. Choose Woodpecker if you need multiple mailboxes or teammates at no cost, or your volume is uneven enough that usage-based pricing wins.
