Frequently Asked Questions
Should letters be handwritten or typed?+−
Typed and printed is more professional for formal use. Handwritten is acceptable for school applications and informal letters.
How long should a formal letter be?+−
Under one page. 200-300 words is ideal. Longer letters lose the reader.
When to use "Yours sincerely" vs "Yours faithfully"?+−
Sincerely: when you know the recipient's name. Faithfully: when starting with "Dear Sir/Madam" without a name.
Can I send a formal letter via WhatsApp?+−
Email is acceptable for formal communication. WhatsApp is too informal for government, banks, or job applications.
Should I include my contact details?+−
Yes. Phone and email below your name help recipient respond easily.
How long until I should expect a reply?+−
Government letters: 15-30 days. Companies: 7-14 days. Schools: 2-7 days. Follow up if no reply within these windows.
