Quick answer

Register on the TOEFL email task is decided by the recipient. To a professor, office, manager or vendor, write formally with no contractions. To a classmate, roommate or another peer, a warm first-name greeting and contractions are correct and are not penalised.

The mistake almost everyone is taught to make

Most preparation advice tells you that the TOEFL email is formal, so avoid contractions and open with Dear Professor. That advice is right about half the time and actively harmful the other half.

The email prompts in the 2026 format vary the recipient deliberately. Across our sixteen writing tests you will write to a professor, a bookstore manager, a mentoring coordinator, a parking office, a lab director, a print shop manager, an elections committee chair, an academic advisor, a campus police office, a regalia vendor, a visiting researcher you met once, a group-project classmate who has gone quiet, and the graduate student whose apartment you are subletting.

Two of those are peers. Writing Dear Sir or Madam to a classmate you have been in a group with for six weeks is as wrong as writing Hey to a parking office. Register is not a fixed level of formality you memorise. It is a judgement you make about a specific reader, and the descriptors reward getting that judgement right.

FAQ

Common questions

No. It depends on who the prompt tells you to write to. Professors, offices, managers, directors and vendors take a formal register. Classmates, roommates, teammates and a tenant you sublet from take a warm peer register where contractions are appropriate.

In an email to an institutional reader, yes, they are a register slip and raters are told to flag them. In an email to a peer they are correct and are not penalised.

Address the role. Dear Bookstore Manager, or Dear Parking Office, is better than To Whom It May Concern, which reads like a form letter.

It is better not to. Frustration is not a required point in any prompt and it moves your tone toward blame. State the facts and the consequence, which are more persuasive than any adjective.

Not in modern academic or professional English. Kindly reply as soon as possible reads as sharp rather than courteous. Use a question with a modal instead: Could you reply when you have a moment?

Full name for an institutional reader, first name for a peer. Either way, sign something. A missing closing is named in the band 2 descriptor.
