Everyone is still speculating about this, but most have been leaning toward the no-cost option being a Gmail address (https://9to5google.com/2022/01/27/g-suite-legacy-transfer-gmail/ https://9to5google.com/2022/01/27/g-suite-legacy-transfer-gm...). The wording on the Google support page mentioning the no-cost option is still vague enough to have me doubting this as well. If the no-cost option isn't Gmail, then there's the option of obtaining new Gmail accounts and transferring the data to them manually. Then the ImprovMX option should work.
