We don’t recommend using masks when you need your identity verified or for very important emails or those where you must receive attachments. For example, you’d want to share your true email address with your bank, your doctor, and your lawyer, as well as when receiving concert or flight boarding passes.
Nid ydym yn argymell defnyddio arallenwau pan fydd angen i'ch hunaniaeth gael ei wirio neu ar gyfer e-byst pwysig iawn neu'r rheini lle mae'n rhaid i chi dderbyn atodiadau. Er enghraifft, rydych chi am rannu'ch cyfeiriad e-bost go iawn â'ch banc, eich meddyg a'ch cyfreithiwr, yn ogystal ag wrth dderbyn tocynnau cyngerdd neu bas byrddio awyren.
