Knowing how to accept a job offer via email or letter matters more than most candidates realise. A verbal yes secures the role. A written acceptance sets the tone for everything that follows: your working relationship, your professionalism, and how the HR team files your start-date confirmation. Done well, it takes under ten minutes. Done carelessly, it can create confusion or look sloppy right before day one.
When to reply and how fast
Most employers expect a written acceptance within 24 to 48 hours of a verbal agreement. If you need more time to review the formal offer letter, it's fine to ask for one or two extra days. Don't ask for a week. The hiring manager has already invested time in you, and a prolonged delay signals hesitation.
Send your acceptance by email in almost every case. A posted letter is appropriate only when the company culture is formal, the employer specifically sent you a physical offer, or the role is in a field where written correspondence is still the norm (law, government, some finance sectors). If you're not sure, email is correct.
What your acceptance must include
A well-structured job offer acceptance covers four things, in this order:
- A clear, direct statement that you're accepting the offer
- The job title and start date, so there's no ambiguity on the employer's side
- A brief expression of enthusiasm (one sentence is enough)
- A request for any next steps or documents you should prepare
That's it. Keep the email short. Hiring managers don't need your life story; they need confirmation. Three short paragraphs is the right length for most acceptances. Four is the ceiling.
A sample email accepting a job offer
Below is a clean, professional template you can adapt. Replace the bracketed details with your own.
Subject: Job offer acceptance – [Your Name]
Dear [Hiring Manager's Name],
I'm writing to formally accept your offer for the position of [Job Title] at [Company Name]. I'm delighted to join the team and look forward to starting on [Start Date].
I've reviewed the offer letter and the terms are as we discussed. Please let me know if there are any documents you'd like me to complete or return before my first day.
Thank you again for the opportunity. I look forward to contributing to [Company Name].
Kind regards,
[Your Full Name]
[Phone Number]
Notice that the subject line names you directly. HR departments process dozens of emails daily; a subject like "Job offer acceptance – Sarah Chen" is instantly findable. A subject like "Re: your offer" is not.
How to accept by letter instead of email
A formal letter follows the same structure but uses proper business letter format: your address at the top right, the employer's address below left, the date, a formal salutation, body paragraphs, and a sign-off. Use "Dear Mr./Ms. [Surname]" rather than a first name, unless you've been on first-name terms throughout the process.
The body of a letter acceptance mirrors the email template above almost word for word. The main difference is the closing: "Yours sincerely" when you know the recipient's name, "Yours faithfully" when you don't. Print on plain white paper, sign in ink, and keep a copy for your own records before posting.
Tone: enthusiastic but not effusive
Candidates sometimes overcorrect here. One line of genuine enthusiasm reads well. Three paragraphs of exclamation points reads as anxious. State that you're pleased or excited, mention one specific thing you're looking forward to (the team, the project, the scope of the role), and move on.
Professional closings like "With best regards" or "Kind regards" work well for acceptances. "Cheers" is too casual. "Respectfully" is too stiff for most industries. Match the tone of the offer letter you received, and you'll rarely go wrong.
What to do if the offer has conditions
If you're accepting an offer but still have an outstanding question (a relocation allowance, a revised start date, a benefits clarification), address it directly in the same email. Don't bury it. Write something like: "I'm delighted to accept. I did want to confirm one point before we finalise: could you clarify whether the role includes [specific item]?" Keep the tone collegial, not combative.
If you negotiated salary and the revised figure is now in writing, confirm that number explicitly in your acceptance. Write: "I'm pleased to accept the offer at the agreed salary of $[X]." This creates a clear paper trail for both parties and removes any scope for later misunderstanding.
Common mistakes to avoid
Don't send the acceptance before you've read the entire offer letter. Read every clause, including the notice period, non-compete terms, and any probationary conditions. Once you send the written acceptance, you've agreed to those terms.
Don't leave the start date vague. If the offer says "on or around 15 September," pin it down in your reply. Write: "I confirm the start date of 15 September." Vague language on both sides creates scheduling headaches.
Don't use "enclosed please find" or similar dated phrases if you're attaching signed documents to your email. Write: "I've attached the signed offer letter for your records." Clear, direct, and professional.
After you send the acceptance
Follow up if you haven't received a confirmation within two business days. A short email is fine: "I wanted to confirm you received my acceptance sent on [date]. Please let me know if you need anything further from me." No apology needed. Chasing a confirmation is normal and expected.
Keep the acceptance email in your sent folder and save a copy of the offer letter you signed. Those two documents are your record of what was agreed. You may need them on your first day, or months later if a discrepancy arises.
