I am writing on behalf of

Don't bury it at the bottom! The reader needs to know who you represent right away. It is like showing your ID card before you start talking. It makes everything you say next feel more 'official.'

Keep it for when you are the 'official' voice.

A very common error is mixing up the prepositions. People often say on behalf to or in behalf of. In modern English, on behalf of is the king. In behalf of usually means 'for the benefit of,' but most people just use on behalf of for everything now. Another mistake is forgetting the of. ✗ I am writing on behalf the company. → ✓ I am writing on behalf of the company. Also, watch out for the spelling of behalf. It's not 'be-half' or 'be-halve.' Just one 'f'! It's a small word that does a lot of work. Don't let it trip you up.

If you want to mix it up, you have options. I am contacting you on behalf of is a popular alternative. If you want to sound slightly less formal, try I'm representing... or I'm speaking for....

Is it too formal? Sometimes, yes. If you know the person well, just say 'I'm emailing for [Name].' Does it work for phone calls? No, you'd say I am calling on behalf of. Is it 'on' or 'in'?

Otherwise, keep it professional! It is a tool for clarity and authority.
