Send Money from Thailand to Poland
A dollar balance in Thailand, a euro credit on a Polish IBAN
The senders here earn US dollars while living or trading in Thailand. Freelancers in Bangkok invoicing abroad, professionals on a foreign payroll, people supporting relatives or students in Poland, and Thailand-based companies paying Polish developers and agencies all draw on the same dollar balance.
Grey sends from dollars and from nothing else. The USD account is provided by Lead Bank with US routing and account numbers attached, so clients, employers and platforms abroad pay into it directly. You convert that balance into euro in the app, see the rate, the fee and the euro total before confirming, and the rate holds once confirmed.
Be clear with your recipient about what arrives, because the currency catches people out. The credit is in euro, and the figure their app displays will be a euro figure, not a zloty one. PKO Bank Polski, Bank Pekao and mBank take the credit on an IBAN that begins PL, and other Polish banks do the same. Where the account itself is a euro account, and plenty in Poland are, no exchange takes place anywhere. If the recipient wants zloty instead, their own bank performs that exchange at its own rate, and holding the euro costs them nothing.

What a transfer to Poland costs
Cost comes from two sources and only one of them carries a label. There is the stated fee, and there is the gap between the quoted rate and the market rate, which is where a provider offering transfers at no charge is usually making its money. The advertised number alone will not tell you which service is cheaper.
Compare the euro figure that is promised. Send the same dollars through Grey and through whichever alternative you were considering, then read what each undertakes to credit to the Polish account. That one figure contains the fee and the margin together.
Then account for the step that is not Grey's. If your recipient asks their bank to turn the euro into zloty, that bank decides the rate and the charge. Ask them what their bank does before treating the euro figure as final, especially on a larger payment where the difference is worth knowing in advance.

Where the dollar to euro rate is fixed, and where it is not

Grey fixes the dollar to euro rate at the moment of confirmation. The market moves on afterwards, and the euro amount from the confirmation screen is still the amount credited to the Polish IBAN.
One conversion is Grey's, and it goes from your dollars into euro. Since you are already holding dollars, there is nothing to exchange beforehand, so the transfer carries a single rate and a single margin rather than two built one on the other.
A second conversion is possible and belongs to the receiving bank. Where the recipient wants zloty, their Polish bank sets both the rate and the cost of changing the euro, and Grey neither performs that exchange nor makes any claim about what it will cost. Accounts that hold euro directly avoid the question altogether, which is worth establishing before the first payment.


How Grey compares with an ordinary bank wire to Poland
A conventional wire to Poland travels through correspondent banks, and each one brings its own cut-offs, working days and deductions, which frequently only become apparent when the recipient counts what landed. Grey sends out of a dollar balance you already hold and credits the PL IBAN in euro, so the amount agreed at confirmation is the amount the recipient should find.
There is also less to gather beforehand. A wire asks for intermediary banks and extra routing fields; here the IBAN carries the payment on its own, over the SEPA network that Polish banks already sit inside. The transfer stays visible in your app from confirmation onwards, instead of vanishing into a chain you have no sight of.
