If your e-mail provider supports it, Customize From Address allows you to make a one-off minor alteration to your From address without having to create a new identity in Account Settings. For example, if your From address is John Doe <john@example.com> you may want to change it to John Doe <john+doe@example.com> or John <john@example.com>.
Zure eposta hornitzaileak onartzen badu, 'helbidetik pertsonalizatzeak' ahalbidetzen du aldaketa txiki bat egitea zure nondik helbidean identitate berri bat sortu gabe kontuaren ezarpenetan. Adibidez, Zure izena Mikel Biteri bada <mikel@example.com> eta Mikel Biterira aldatu nahi baduzu <mikel+biteri@example.com> or Mikel <mikel@example.com>era.
