DonkeyMails & No-Minimum are no doubt  the leading sites in PTR industry with the largest memberbase and the best paying records. I suppose you already belong to them if you do PTR.

But do you know they have 2 sister sites?

Get Paid Mail  You Ro Mail

A fair amount of 0.25c above emails daily and 0.1c PTCs, points opt-in only

0% activity requirement to earn from downline

I have been paid 5 times so far, total $43, payments via Masspay so no fees!

Don't be scared by the $8 or $10 minimum payout, they have been around for years, every penny you earned will be yours
