Hi Mr. Torres,

I’m very excited to accept the Backend Engineering Intern offer you shared yesterday! This is exactly the opportunity I was hoping for, and I’m ready to get started July 1st as discussed.

Thanks again for everything, I can’t wait to meet the team.

Frequently Asked Questions about Sample Letter for Internship Acceptance

How soon should I send my internship acceptance letter?

You should send your acceptance letter within 24 to 48 hours of receiving the official offer. Always reply before the explicit deadline listed on your offer documentation.

Can I accept an internship offer verbally first?

It is completely fine to thank them and accept verbally over the phone first. Always follow up with a written formal acceptance to create a paper trail for both parties.

How long should an internship acceptance letter be?

An ideal acceptance letter is 3 to 5 short paragraphs, or roughly 100-200 words total. You do not need to write a long message for this communication.

Do I need to sign my internship acceptance letter?

For formal corporate roles you may be asked to sign and return a scanned copy. For most email acceptances, your full name at the bottom counts as confirmation.

Can I negotiate terms after sending my acceptance letter?

You should finalize all negotiations before sending your formal acceptance. Only raise last minute adjustments for unavoidable personal circumstances after accepting.

Should I mention other offers I am declining?

You do not need to mention other offers in your acceptance letter. You only need to confirm you are accepting this specific role.

What if I make a typo in my acceptance letter?

If you spot a small typo after sending, send a short polite correction follow up. Always proofread names, dates and job titles twice before hitting send.

Can I send an acceptance letter via text message?

Never send your formal acceptance over text message. Always use email or the official company application portal for this important communication.

A good acceptance letter doesn’t need to be long or fancy. It just needs to be clear, polite, and on time, confirming all the details that matter for both you and your new team. Every example in this guide is built to avoid awkward missteps and start your internship with confidence.
