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>.
Má thacaíonn do sholáthraí le seoltaí ríomhphoist saincheaptha, beidh tú in ann mionathrú a dhéanamh uair amháin ar an seoladh a úsáidtear le do chuid ríomhphoist a sheoladh, gan aitheantas nua a chruthú sna Socruithe Cuntais. Mar shampla, dá mba é "Tadhg Ó Ródaí <tadhg@example.com>" an seoladh a seolann tú ríomhphost uaidh, b'fhéidir leat é a athrú go dtí "Tadhg Ó Ródaí <tadhg+o+rodai@example.com>" nó "Tadhg <tadhg@example.com>".
